The Sea Otter Classic has traditionally had a mountain bike focus and, while off-road riding still characterises the event, every two-wheeled discipline is now well represented in what has become North Americas biggest and most important cycling festival.As a result, there was no shortage of new road tech for us to hunt out in California, including new and recently released bikes from Blackheart, FiftyOne, Haro, ENVE, Van Rysel, BMC, Ritchey, Parlee, Giant, Bridge Bike Works and Canyon.From Blackhearts new alloy frame to Parlees endurance bike, via Haros diversion into drop bars and FiftyOnes addition of a stock road frame as well as big-name bikes from BMC, Giant and more theres something for everyone here.Blackhearts all-new Road AL alloy race bikeNew from LA-based Blackheart, the Road AL. - George Scott / Our MediaThe Road AL is Blackhearts newest model, launched at Sea Otter 2024.Its based around the same geometry as the LA brands Road Ti, launched last year, with racy angles and eight stock sizes, from 46cm to 62cm. The geometrys not too dissimilar from a Giant TCR in terms of stack and reach, and it has a steeper head tube angle.The frame combines the modern and the classic, with relatively simple tube shapes, dropped stays, an integrated front end and clearance for 32mm tyres.Subtle tube shaping for the Blackheart Road AL. - George Scott / Our MediaIts made from double-butted 7005 aluminium, with a subtle Kammtail shape to the down tube and gentle curving seatstays. The frame is finished with Cerakote, a heat-cured ceramic paint.Blackhearts representative at Sea Otter said the frame is designed around common standards, with no proprietary parts. Theres a threaded T47 bottom bracket, a round 31.6mm seatpost, SRAMs Univeral Derailleur Hanger, and compatibility with 1x and 2x drivetrains. There's clearance for 32mm tyres.Room for 32mm tyres. - George Scott / Our MediaThe frame costs $1,999 and 10 build options are available through Blackheart, starting with a SRAM Rival AXS 1x version for $3,649, and rising to $7,449 with 1x Campagnolo Super Record Wireless. That's with a set of DT Swiss A 1800 Alloy wheels Blackheart also offers a range of Hunt, Zipp and ENVE wheel upgrades.You can also upgrade the tyres, bottom bracket, rear derailleur cage and handlebar/stem, as well as adding a power meter or changing the handlebar width and stem length.We love high-end alloy. - George Scott / Our MediaThe Road AL was launched at Sea Otter 2024. - George Scott / Our MediaThere are 10 build options. - George Scott / Our MediaSRAM's Universal Derailleur Hanger features. - George Scott / Our MediaA fresh look at Blackhearts Gravel ALThe Gravel AL also took centre stage on Blackheart's Sea Otter booth. - George Scott / Our MediaThe Blackheart range also includes an all-road bike, with aluminium and titanium frame options and 40mm of tyre clearance, and this, the Gravel AL, launched in January.The frame has clearance for 47mm tyres, but youll notice the relatively tight clearance at the rear of the bike. Blackheart wanted to combine a slightly slack angle (for stability) with a tight rear triangle to keep the handling relatively reactive.This one also starts at $1,999 for the frameset, with SRAM and Shimano build options.Clearance is quite tight with a big tyre. - George Scott / Our MediaThere's plenty of room up front. - George Scott / Our MediaThe Gravel AL also uses a T47 bottom bracket. - George Scott / Our MediaFiftyOne adds the Sika, a stock road frame with big tyre clearanceThe FiftyOne Sika also broke cover at Sea Otter. - George Scott / Our MediaFiftyOne is best known for its custom bikes, as well as for producing hard-hitting bikes for the likes of UFC star Conor McGregor and heavyweight boxer Anthony Joshua.However, the Irish brand introduced a stock gravel bike, the FiftyOne Assassin, a couple of years ago and now has a production road bike, the FiftyOne Sika.Very pretty. - George Scott / Our MediaThe 690g claimed frame weight (size medium) is the headline-grabber here. The frame also has clearance for 40mm tyres and is based around a real-world geometry for everyday riders, not stretchy pros, according to FiftyOnes founder, Aidan Duff.Duff says FiftyOnes experience in building more than 500 custom bikes has fed into the development of the Sika, including fit data and tube shapes. FiftyOne's signature seatstay shape. - George Scott / Our MediaThe seatstays, in particular, are very distinctive, with a pencil-thin design that adopts FiftyOnes now-trademark shape.Other features include a 27.2mm seatpost with an external clamp, T47 bottom bracket, a Universal Derailleur Hanger and Sikas own one-piece cockpit.Big tyre clearance is all the rage. - George Scott / Our MediaWe love the finish on this. - George Scott / Our MediaFiftyOne is best known for its fully custom frames. - George Scott / Our MediaA round seatpost keeps things simple. - George Scott / Our MediaHaro drops into road bikes with the new RivetteWe didn't expect to see new drop-bar bikes from Haro. - Jack Luke / Our MediaThe Haro Rivette is a new aero-inspired race bike from a brand normally associated with BMXs and affordable mountain bikes.The bike demonstrates many traits of the contemporary all-rounder aero bike internal cable routing, truncated aerofoil tubing, lightly dropped chainstays and a beefy head tube are all present and correct.Jack Luke / Our MediaPictured is the top-spec Rivette, costing $7,999 with Shimano Dura-Ace Di2 R9200.Vision 45 SL wheels and a one-piece cockpit from BlkTec which is better known for its wild star-shaped wheels complete the build.ENVEs new Fray all-road bike with a Classified hubThe ENVE Fray launched a week before Sea Otter. - George Scott / Our MediaENVE released the Fray a week before Sea Otter, with the Utah firms latest bike sitting between the Melee race bike and MOG gravel bike in an expanding line-up.This is a genre-blurring bike that, with room for squishy 40mm tyres, some might call an all-road bike, and some might call an endurance bike, given how tyre clearance has ballooned in that sector over the past 12 months.ENVE is now working with Classified. - George Scott / Our MediaENVE had a rather special, custom-painted Fray on its booth at Sea Otter, but well save that for a separate round-up of some of our favourite custom bikes from the show. Watch this space.However, Classified also had a Fray on display, thanks to a new partnership with ENVE.With the Powershift hub replicating the work of a front derailleur, the drivetrain is streamlined. - George Scott / Our MediaClassified, if youre not familiar, produces a rear hub the Powershift which replaces the front derailleur. The idea is that Powershift offers the range and versatility of a 2x drivetrain, but with a streamlined 1x configuration up front.This new partnership means ENVE will be offering a range of wheels (the Foundation, G Series and SES Series lines) and Melee, MOG and Fray builds with Classified Powershift.Van Rysels RCR aero race bike is finally availableVan Rysel featured prominently at Sea Otter once again. - George Scott / Our MediaOkay, this one broke cover at last year's Sea Otter and was one of the standout highlights of the show but now, a year later, the Van Rysel RCR is finally available to the public.Since the 2023 show, Van Rysel has officially launched the RCR and re-entered the WorldTour peloton thanks to a new partnership with the Decathlon AG2R La Mondiale team.This Van Rysel RCR Rival looked very tasty. - George Scott / Our MediaVan Rysel is offering the RCR in SRAM Rival AXS (4,500 / $5,499), Shimano Ultegra Di2 (5,500 / $TBC) and SRAM Force AXS builds (5,500 / $6,999).There's also a replica of the team bike for 9,000 / $10,999, although that's temporarily out of stock (in the UK, TBC in the US) having sold through pre-orders last week.There's a SRAM Force AXS spec, too. - George Scott / Our MediaLow and very long. - George Scott / Our MediaFor the future WorldTour stars. - George Scott / Our MediaBMCs revamped Roadmachine in the fleshAnother look at the new BMC Roadmachine. - George Scott / Our MediaBikeRadars Oscar Huckle was on the launch of BMCs revamped endurance bike a couple of weeks ago and was seriously impressed you can read his BMC Roadmachine review.30mm rubber as standard. - George Scott / Our MediaStill, we couldnt resist swinging by the BMC booth to look at the recently released Roadmachine.A top-spec build for Sea Otter. - George Scott / Our MediaOnce again, big tyres are the headline here can you see a trend developing with the latest endurance road bikes? with room for 40mm rubber. Theres also nifty down tube storage, a neatly integrated rear light and Stealth Dropouts.The Roadmachine X is the gravel-inspired spec. - Jack Luke / Our MediaBMC will offer the new Roadmachine in road and gravel (Roadmachine X) builds, while theres also a Roadmachine AMP e-road variation.The Ritchey Montebello is a utilitarians dreamMudguards were out of place at a dry and dusty Sea Otter, but that doesn't make this bike any less delightful. - Jack Luke / Our MediaWith polished fenders sparkling resplendently in the Californian sunshine, mudguard magpie Jack Luke was drawn towards the new Ritchey Montebello from across the show.The Montebello is an all-new steel road bike that pairs relaxed geometry with mounts for a front rack and mudguards (with clearance for 36mm tyres or 4mm without fenders), and dynamo light routing.Time for something different. - Jack Luke / Our MediaTo prove the credentials of the brand's new randonneur bike, Ritcheys marketing manager, Fergus Liam, rode a pre-production Montebello at the 1,200km Paris-Brest-Paris event.Weve covered the Ritchey Montebello in more detail here.The silver finish kit is a great match for the red paint. - Jack Luke / Our MediaThe same seat clamp design is used across several of Ritchey's bikes. - Jack Luke / Our MediaRacked up and ready. - Jack Luke / Our MediaCut-outs were added to this iteration of the dropouts to reduce weight. - Jack Luke / Our MediaParlees nude Ouray turns headsParlee is back with the Ouray. - Scott Windsor / Our MediaAfter a couple of lean years, during which the brand was rescued from the brink of bankruptcy, Parlee was back with a bang at Sea Otter.The new Ouray turned heads on Parlees stand, thanks partly to the nude carbon finish, protected only by a lightweight but durable, according to Parlee wax coating.The Ouray has a nude carbon finish. - Scott Windsor / Our MediaThe Ouray is a monocoque frame, made in one piece, and Parlee is so confident in the layup of the carbon fibre that it wants to keep everything on display, without any paint or even clear-coat lacquer, to distract from the finish.The Ouray joins the Z-Zero, RZ7 and Chebbaco in the Parlee line-up. Its a bike that points to the future, compatible with only electronic groupsets and, like the Blackheart and FiftyOne bikes also featured here, SRAM UDH.Neat and tidy. - Scott Windsor / Our MediaParlee says the Ouray is designed around open standards, and supplies the bike with custom, 3D-printed headset spacers for PRO, ENVE and FSA cockpits.Giant stays loyal to the TCROne of this year's biggest launches so far, the new Giant TCR. - George Scott / Our MediaFinally, heres the latest Giant TCR another bike launched in the build-up to Sea Otter.Weve covered the new Giant TCR in detail and have already reviewed this latest iteration so will keep this brief for now.Giant is staying loyal to the TCR marque. - George Scott / Our MediaWhile some brands are slimming down their ranges by combining their aero and lightweight lines into one do-it-all road bike, Giant has stayed loyal to the TCR name in launching this 10th iteration, while continuing to develop (and reduce the weight of) the Propel aero bike.The flagship TCR Advanced SL frame now weighs a claimed 690g for a size medium, while getting subtle aero upgrades both to the tube shapes and with the cable routing going internal and a new handlebar.The TCR's had a light aero makeover. - George Scott / Our MediaBridge Bike Works Surveyor race bike is a work of artThe Surveyor is Bridge Bike Works' first production bike. - Scott Windsor / Our MediaBridge Bike Works Integrally Threaded Carbon Bottom Bracket was a highlight of Sea Otter 2023.Most carbon bikes with a threaded bottom bracket bond an alloy sleeve into the frame, with the bottom bracket threading into this.Bridges design is unique, with the bottom brackets threading directly into threads moulded (not cut) into the frame.This wonderful colour is dubbed 'Isle of Man' green. - Scott Windsor / Our MediaAfter two years of development, the Canadian brand is now ready to bring a full bike to market, kicking things off with the Surveyor.Priced at around $4,000 with a stock paint option, the Surveyor is a road race bike with clearance for 40mm tyres.Despite that gravel-bike style clearance, Bridge says the Surveyors geometry figures are firmly road-like. It expects to see customers evenly split between true road builds and a gravel-lite spec, as pictured here.Canyon targets rugged riding with new Grizl:On e-gravel bikeWith a Bosch motor and RockShox suspension fork, Canyon is pitching this one at big adventures. - George Scott / Our MediaFinally, here's Canyon's new electric gravel bike, the Grizl:On.Launched in March, the Grizl:On is a new addition to Canyon's e-gravel line-up, joining the Grail:On.The Grizl:On uses Bosch's new Performance Line SX motor for relatively lightweight electrification, with the drive unit adding a claimed 4kg. It's not as powerful as full-fat ebike motors, such as the 90Nm Bosch Performance Line CX, but Canyon says its lower weight and torque results in a more natural ride feel.
