Reynolds is well known for its carbon rims and wheelsets, but now, the brand is switching up materials with the launch of its alloy range. This new alloy lineup spans the off-road disciplines from gravel to downhill, and everything in between. With it, the brand says it aims to bring the same precision, purpose, and performance-driven philosophy that define Reynolds carbon range to its aluminum counterparts.In doing so, Reynolds aims to prove that it isnt defined by its carbon expertise, and even created its own hashtag: #MoreThanAMedium. Reynolds says, From the 6th element (carbon) to the 13th (aluminum), the new Reynolds range reaffirms a truth the brand has lived since its inception: the wheel is not defined by what its made of, but by how its made.Reynolds Alloy CollectionReynolds new Alloy collection covers five genres of off-road riding, with purpose-built rims and wheels to suit their intended use. Reynolds tells us that each new wheel has been designed with its RTV (Reynolds Terrain Versatility) philosophy, that defines how we engineer wheels for every discipline without compromise. The collection includes gravel, XC, trail, enduro, and downhill rims, with some categories featuring multiple spec levels to suit varying needs, preferences, and budgets. Lets check them out.Reynolds Gravel AluminumThe 26mm internal width is intended to pair well with modern gravel tire widths, while the shallow depth is meant to provide a compliant and comfortable ride.Reynolds says the G30 Expert Gravel Wheelset was developed to create an aluminum wheel that embodies the smooth, responsive, and efficient ride of Reynolds carbon, while delivering everyday durability and ease of ownership. The 700c rims are made with a geometry and construction that promote versatility and comfort for long days in the saddle.The double-wall, welded-joint aluminum rims have a 30mm external and 26mm internal width, a hooked bead, and a tubeless-ready channel thats designed to work with modern high-volume gravel and MTB tires between 40mm and 56mm. The shallow, 17mm rim depth is meant to provide a compliant ride for comfort and control.The Ringl SRX hubs use 3-pawls on a 30-tooth ratchet for 12-degree engagement, and were developed with Reynolds ULD (Ultra Low Drag) approach for maximum efficiency.G30 Gravel Expert SpecsWheel size: 700cOuter rim width: 30mmInner bead width: 26mmHubs: Ringl SRX, 12-degree engagementFreehub body: Alloy HG-Road, XDRHub spacing: Front: 100x12mm, Rear: 142x12mmBrake rotor interface: 6-boltSpoke count: 28Rim weight: 465gWheel weight: Front: 793g, Rear: 916g, Total: 1709gReynolds XC AluminumReynolds new XC wheels are relatievly lightweight and come in two hub spec options.Reynolds says the new A309 XC series was born from the carbon benchmark with the same design philosophy applied to 6069 aluminum. The result is an XC wheel that mirrors the crisp, confident ride of its carbon counterpart while delivering the dependability and value of alloy. With a 30mm internal width, a hooked bead, and a tubeless-ready channel, the A309 XC rims are optimized for modern XC tire widths.The A309 XC wheels come in two spec levels, with the primary difference being the hubs. The Pro is built around Ringle Super Bubba hubs with quick, 4-degree engagement. The Expert is built with Ringle SRX hubs with 12-degree engagement.The Ringl Super Bubba X hubs have quick, 4-degree engagement.A309 XC SpecsWheel size: 29Outer rim width: 34mmInner bead width: 30mmHubs:Pro: Ringl Super Bubba X, 4-degree engagementExpert: Ringl SRX, 12-degree engagementFreehub body: Shimano Microspline or SRAM XD (Shimano HG available)Hub Spacing: Front: 110x15mm, Rear: 148x12mmBrake Rotor Interface: 6-boltSpoke count: 28Weight:Pro: Front: 814g, Rear: 947g, Total: 1761gExpert: Front: 872g, Rear: 962g, Total: 1834gReynolds Trail AluminumThe new Trail Alloy wheels are wider than most at 32mm internal, with a relatively shallow depth.Reynolds says the new A327 and A329 wheels were engineered from the ground up to meet the demands of modern trail riding. They feature a completely new rim design with a wider-than-average 32mm internal width, which they say is intended to optimize the tire-to-rim interface. Reynolds claims the added width provides a broader, stronger base for aggressive cornering and high-volume tire support, while reinforced sidewalls resist dents and pinch flats when the trail turns technical. And the low-profile of the 6069 aluminum rim maintains compliance and comfort over the chatter.Like the XC wheels described above, the Trail Alloy wheels come in two aftermarket spec levels, as well as an OEM-only Comp version. The Trail Pro comes with Ringl Super Bubba X hubs with 4-degree engagement and gets premium waterslide graphics. The Trail Expert uses the Ringl SRX hubs with 12-degrees between engagement points.The Trail Pro wheel comes with fancy graphics and the Ringl Super Bubba X hubs.A327 A329 Trail SpecsWheel size: 29, 27.5Outer rim width: 35.5mmInner bead width: 32mmHubs:Pro: Ringl Super Bubba X, 4-degree engagementExpert: Ringl SRX, 12-degree engagementFreehub body: Shimano Microspline, SRAM XD, Shimano HGHub Spacing: Front: 110x15mm, Rear: 148x12mm, 157x12mmBrake Rotor Interface: 6-boltSpoke count: 28Weight:Rim: 27.5: 477g, 29: 508gPro:27.5: Front: 827g, Rear: 960g: Total: 1787g29: Front: 855g, Rear: 988g, Total: 1843gExpert:27.5: Front: 865g, Rear: 957g, Total: 1824g29: Front: 895g, Rear: 985g, Total: 1880gReynolds Enduro AluminumThe Enduro Alloy wheels are meant to provide gravity strength in a pedalable package.The new A307 and A309 Enduro wheels were built to withstand the abuse of longer travel bikes and enduro-style terrain. Reynolds says they were conceived with a clear objective: deliver gravity-ready strength while preserving the efficiency required for all-day riding. The 6069 aluminum rims have a precision-welded joint for impact resistance and durability, with a 30mm internal width thats standard for the category.According to Reynolds, the Enduro Aluminum wheels are designed for aggressive enduro lines and the added torque of e-MTB riding, they provide a composed, predictable feel when speeds rise, and impacts become unavoidable. The A307 and A309 Enduro wheels come in the same Pro and Expert spec levels as the other mountain bike wheels. The Pro wheels come with the Ringl Super Bubba X hubs with 4-degree engagement, and the Expert wheels are built around the Ringl SRX hubs with 12-degree pickup.The SRX hubs on the Expert build.A307 A309 Enduro Specs:Wheel size: 29, 27.5Outer rim width: 35.5mmInner bead width: 30mmRim Depth: 20mmHubs:Pro: Ringl Super Bubba X, 4-degree engagementExpert: Ringl SRX, 12-degree engagementFreehub body: Shimano Microspline, SRAM XD, Shimano HGHub Spacing: Front: 110x15mm, Rear: 148x12mm, 157x12mmBrake Rotor Interface: 6-boltSpoke count: 28Weight:Rim: 27.5: 477g, 29: 508gPro:27.5: Front: 827g, Rear: 960g: Total: 1787g29: Front: 855g, Rear: 988g, Total: 1843gExpert:27.5: Front: 865g, Rear: 957g, Total: 1824g29: Front: 895g, Rear: 985g, Total: 1880gReynolds Downhill Aluminum:The DH Alloy wheels come in the Pro build only.According to Reynolds, the A307 and A309 Downhill wheels were designed with a singular focus: maximum strength, stability, and reliability under extreme load. The 6069 aluminum rims have a precision-welded joint for structural consistency and durability, along with a bump up to 32 spoke counts for added strength. The 30mm internal width pairs with modern gravity tire widths and casings, and they come in both 27.5 and 29 diameters to suit rider needs and preferences.The A307 and A309 DH come in a Pro build only, featuring the Ringl Bubba hub equipped with Reynolds proprietary CLOCKD adjustable engagement system. This unique dual-ring design allows riders to choose between 4- and 8-degree engagement angles to suit their needs and preferences.The Ringl Buba hub uses J-bend spokes, and it features Reynolds CLOCKD adjustable engagement system.A307 A309 DH Pro SpecsWheel size: 29, 27.5Outer rim width: 35mmInner bead width: 30mmRim Depth: 20mmHubs:Ringl Bubba w/CLOCKD, 4- or 8-degree engagementFreehub body: Shimano Microspline, SRAM XD, Shimano HGHub Spacing: Front: 110x20mm, Rear: 148x12mm, 157x12mmBrake Rotor Interface: 6-boltSpoke count: 32Weight:Rim: 27.5: 515g, 29: 545gWheels:27.5: Front: 930g, Rear: 1130g: Total: 2060g29: Front: 960g, Rear: 1160g, Total: 2120gReynolds Alloy Collection: AvailabilityReynolds new collection of alloy wheels launches today and should be available soon, if not immediately.

For years, the Cervlo S5 has been seen as the aero bike to beat. As a true pioneer of aerodynamic road design,we were keen to test it out in our 2026 aero road bike comparison. Does the S5 remain the benchmark in 2026, or have bold new aero concepts taken the lead?Cervlo S5 | 7.38 kg in Size 56 | 13,999 | Manufacturers WebsiteAero is everything. Few brands embody that mantra as consistently as Cervlo. For the brand with Canadian roots, it is not just a marketing slogan, but part of the companys DNA. From the very beginning, with bikes like the Soloist, they focused on one central question: how do you make a road bike measurably faster?Those engineering roots are still visible in every detail, and no bike showcases them as uncompromisingly as the S5. One glance at its silhouette is enough: the bayonet fork, the striking cockpit, the sculpted tube profiles shaped in the wind tunnel. For years, the S5 has set the benchmark in aerodynamic road design. Building on the iconic 2019 silhouette, Cervlo refined the concept for 2022, and again for 2025. Rather than starting from scratch, they sharpened what was already an exceptionally fast system, focusing on targeted improvements rather than a radical redesign.But is steady evolution enough when rivals now follow similar paths? In our 2026 aero road bike review, the S5 faces a new generation of high-speed machines that approach aerodynamics with the same single-minded focus that once defined Cervlo. The decisive question is whether pure efficiency is still enough to stay at the front, or whether being the benchmark today requires more than just maximum aero performance.All Aero? The Cervlo S5 PhilosophyIn this group test, the Cervlo S5, alongside the Factor ONE, is the bike that makes the fewest concessions to broad appeal something which defines its character. While many brands aim to strike a careful balance between comfort, weight and aerodynamics, Cervlo remain firmly committed to their philosophy: maximum efficiency first.The signature bayonet fork, the striking V-shaped cockpit and the boldly sculpted tube profiles are far more than visual flair. They are the physical expression of an uncompromising Aero is everything approach. Every line, every edge and every surface is shaped by that principle.Signature MoveThe distinctive bayonet fork is not a gimmick, but Cervlos aero signature, even if it is no longer unique in this test field.Comfy!Despite its uncompromising look, the rear end offers noticeable damping, making it one of the most comfortable bikes in this aero road bike review.Since the first generation, which established the S5s distinctive style, the concept has been refined in detail. The front end has grown taller and longer, and the cockpit is now integrated even more efficiently. The fact that this works is evident in the pro peloton. At Team VismaLease a Bike, riders such as Jonas Vingegaard regularly choose the S5, even in mountainous races. That alone speaks volumes about its balance. While Pauline Ferrand-Prvot opts for the lighter Cervlo R5 when outright climbing efficiency is the priority, others deliberately stick with the S5, because the watts saved against the wind often matter more than a few grams on the scales even in the mountains.V for VelocityThe V-shaped one-piece cockpit quickly settles you into a proper aero tuck.FiddlyThe deeply recessed seatpost clamp is tricky to access and can test your patience, especially in a direct comparison.No half measuresThe big gearing may feel ambitious on climbs, but it rewards you with serious speed on the other side.With 392 mm of reach and 565 mm of stack, the S5 sits in a modern, sporty position, without pushing you into extremes. It does not force you into an uncomfortable aero tuck, but enables an aggressive position that you can realistically maintain for hours. The specialist DNA shows in the details. Short 405 mm chainstays and a compact 982 mm wheelbase give the bike a distinctly eager, punchy character. At 7.38 kg, it is not among the lightest bikes in the field, especially when compared with the MERIDA REACTO TEAM or the featherweight ROSE Shave FFX.Size485154565861Top Tube520 mm535 mm550 mm565 mm581 mm595 mmHead Tube64 mm82 mm104 mm125 mm152 mm173 mmHead Angle71727373.573.573.5Seat Angle737373737373Chain Stay405 mm405 mm405 mm405 mm405 mm405 mmBB Drop74.5 mm74.5 mm72 mm72 mm69.5 mm69.5 mmWheelbase973 mm974 mm975 mm982 mm999 mm1,013 mmReach367 mm376 mm384 mm392 mm401 mm409 mmStack496 mm519 mm542 mm565 mm588 mm608 mmRace Ready The Spec Of The Cervlo S5The Cervlo S5s build follows its full aero, race-focused brief without compromise. Nothing is softened or toned down. Every component is chosen with one goal in mind: maximum efficiency at high speed.The gearing alone makes that clear. Shimanos DURA-ACE Di2 drivetrain with a 56/40 t chainset is a bold statement. For many amateur racers, that setup may feel a touch ambitious on steep climbs. Yet it is precisely this configuration that allows the S5 to come alive at high speeds and on descents. In context, it makes sense. While MERIDA and BMC offer a 36 x 30 as their easiest ratio, which is hardly relaxed either, the Cervlo delivers significantly more top-end speed. If you can put the power down, this bike gives you exactly the right tool for the job.At the heart of the build sit the deep-section Reserve 57|64 wheels, with DT Swiss 180 hubs. With a 57 mm rim up front and 64 mm at the rear, they underline the S5s uncompromising aero focus, integrating seamlessly with the frame platform. Their depth brings impressive composure and a smooth, settled ride feel, yet they prove more comfortable than you might expect.The 25 mm internal rim width is paired with 29 mm wide Vittoria Corsa Pro TLR tyres, which measure up at exactly 29 mm once installed. Aerodynamically optimised, with low rolling resistance and a beautifully supple ride quality, they fit the concept perfectly. On the road, they deliver tangible comfort and a reassuringly planted feel.The cockpit remains fairly classic with a 400 mm handlebar width. If you want to push further into an aggressive aero tuck, switching to a narrower option is an easy way to fine-tune your position. Cervlo even offer a free cockpit swap to make sure you get the optimal width for your position.All in, the spec is a clear expression of Cervlos philosophy: maximum performance at high speed. That focus comes at a cost. At 13,999, the S5 is the most expensive bike in our 2026 aero road bike review. Only the Factor ONE would exceed that in a hypothetical top-spec build, but our tested mid-spec model comes in lower at 13,399. Cervlo therefore set the financial benchmark in this comparison. The question is whether the performance on the road truly justifies that premium.Cervlo S5 2025 13,999SpecificationsSeatpost Cervlo SP34 D-ShapedBrakes Shimano DURA-ACE BR-R9200 160/160 mmDrivetrain Shimano DURA-ACE Di2 R9200 2 x 12Chainring 54/40 TStem Cervlo HB19 100 mmHandlebar Cervlo HB19 400 mmWheelset Reserve 57/64 12 x 100 / 12 x 142Tires Vittoria Corsa Pro 700 x 29cCranks Shimano DURA-ACE FC-R9200 170 mmCassette Shimano DURA-ACE CS-R9200 1134TTechnical DataSize 48 51 54 56 58 61Weight 7,38 kgSpecific FeaturesBayonet forkV-shaped cockpitCustom UDH derailleur hangerCervlo S5 in Review Efficiency Takes the LeadThe Cervlo S5 accelerates from a standstill with surprising ease, and delivers more punch on climbs than you might expect from such a single-minded aero race bike. A big part of that comes down to the geometry, which Cervlo now use across several models. With identical core figures, the Californians seem to have found a platform that works equally well for the climbing-focused R5 and the aero-driven S5. Once you are up to speed, this bike just wants to go even faster.That said, when you line it up against especially lively bikes such as the ROSE Shave FFX or the MERIDA REACTO TEAM, the S5 lacks a touch of explosiveness uphill. It slots in just behind the BMC and Wilier in this regard. The comparatively heavy Reserve wheelset and the aggressive gearing both play their part. Even so, the S5 climbs efficiently and confidently. It feels steady and powerful, rather than razor sharp more of a diesel engine than a pure sprinter on steep gradients.Once you are up to speed, whether on flat roads or in a full-gas sprint, the Cervlo S5 plays to its strengths without compromise. The high frame stiffness, aerodynamically optimised silhouette and large chainrings combine to make the bike feel easier the faster you go almost as if there is no upper limit. In terms of outright efficiency, the S5 ranks among the clear front runners in our 2026 aero road bike review. Thanks to the subtle rise in the cockpit, you can quickly settle into a low, slippery position, and hold it comfortably over long distances.Here, the S5 clearly distances itself from more versatile aero all-rounders such as the Wilier Filante or the ROSE Shave FFX, operating on a similar level to dedicated aero specialists like the Factor ONE. In a sprint, it remains composed and torsionally stiff, converting your effort directly into forward drive.Handling is precise, but not instantly intuitive. Like the Factor, the Cervlo rewards a short familiarisation phase. At high speeds, it feels planted and predictable, tracking confidently and remaining impressively stable. As the pace drops or the road becomes tighter and more technical, the handling is less intuitive than that of the MERIDA, and noticeably less playful than the BMC. On fast descents and long straights, its pronounced composure comes to the fore. Effortless agility and rapid changes of direction are not its main focus. With its deep front end and deep-section rims, the S5 reacts noticeably in gusty crosswinds. It remains manageable at all times, but it does require a sure hand and a bit of experience.Comfort is where the S5 genuinely surprises. Despite its uncompromising concept, it ranks alongside the Wilier and BMC among the more comfortable bikes in this aero road bike comparison. The rear end in particular offers perceptible damping, without ever feeling vague or diluting the bikes race-focused character.In the end, the Cervlo S5 is not a playful all-rounder but a highly efficient high-speed tool. If you thrive on sustained pressure and love riding fast, you are getting one of the quickest and, at the same time, most comfortable aero race bikes in the entire test field. Tuning tip: Try a longer, narrower cockpit to maximise your aero tuck.Who is the Cervlo S5 Made For?The Cervlo S5 is not a one-dimensional specialist, but an aero race bike with a surprisingly broad range. It truly comes into its own wherever speed needs to be built and sustained. Flat to rolling races, long solo breakaways, high-speed sprints from a rolling start, or fast stages ridden at consistently high pace are exactly where this bike shines.Unlike more radical concepts such as the Factor ONE, the S5 also performs impressively well on more demanding terrain. Thanks to its shared geometry with the R5 and its noticeable rear compliance, it remains competitive on rolling courses and longer climbs. Only when the road tilts up sharply and attacks come thick and fast does it lack a touch of snap. Races defined by constant changes of pace will expose that slight deficit in reactivity.Tight criteriums or courses that demand repeated accelerations from low speed are not its ideal playground. In those scenarios, bikes such as the MERIDA REACTO TEAM, the BMC Teammachine R01 or the ROSE Shave FFX feel distinctly more agile and punchy.AccessibilityBeginnerProBLING FACTORlowhighAGILITYsluggishplayfulSTABILITYnervousconfidentHANDLINGdemandingintuitiveEFFICIENCYlowhighACCELERATIONsluggishnimbleFUN FACTORdulllivelyCOMFORTfirmcomfortableVERSATILITYlowhighHelmet Sweet Protection Falconer Aero 2Vi MIPS Block Party LTD | Glasses Sweet Protection Shinobi RIG Reflect | Jersey Canyon CFR Herren Langarmtrikot | Bibs Canyon CFR Cargo Men Bibshort | Shoes Specialized S-Works Ares 2 | Vest Pas Normal Studios Mechanism Stow Away GiletConclusion on the Cervlo S5The Cervlo S5 remains one of the fastest aero road bikes on the market in 2026. It does not win you over with playful handling or featherweight agility, but with sheer efficiency the core principle that defines Cervlo. The faster you ride, the more clearly that efficiency reveals itself. Compared with more versatile aero all-rounders, the S5 gives up a touch of explosiveness. In return, it delivers a ride feel purpose-built for sustained high speed. The fact that it manages to remain surprisingly comfortable is one of the most welcome surprises of this otherwise uncompromising concept.TopsSurprisingly high comfortOutstanding efficiencyImpressive stabilityFlopsFiddly seatpost clampFind out more at cervelo.com.The TestfieldThis bike was tested as part of the 2026 Aero Road Bike Group Test for an overview of this group test as well as all other tested aero bikes, check out the 2026 Aero Road Bike Group Test.All bikes in test: Cervlo S5 | Factor ONE | MERIDA REACTO TEAM | ROSE Shave FFX | Wilier Filante SLR ID2Der Beitrag Cervlo S5 Review in our 2026 Aero Road Bike Comparison erschien zuerst auf GRAN FONDO Cycling Magazine.
