CyclistHunt Sustain wheels use recycled materials to reduce environmental impact as brand aims for net zeroHunt Wheels has launched three new wheelsets, but rather than the usual lighter, faster, stiffer mantra, the Sustain Phase One wheel range is aimed at reducing carbon emissions and creating a more sustainable wheel production process.The Sustain range includes the 42 Carbon Disc Ti wheelset with rims with 10% recycled carbon fibre and titanium hubs, priced at 1,149. The 4 Season All-Road Disc wheel rims have 75% recycled aluminium content and are priced at 449, while the Trail Wide 29 MTB wheelset also has 75% recycled rim content and is priced at 489.All three wheelsets are assembled in Europe using locally made parts to reduce transport costs.

How Hunt is targeting emissions reductionHunt says that its been researching how to measure and reduce the businesss environmental impact for a few years.The new Sustain wheels are updates of three of the companys most popular wheelsets, but redesigned with new specs, using recycled content in both the carbon and alloy rimmed products and less resource-intensive manufacturing processes. In addition, Hunt has reduced the distances the Sustain wheels and their components are transported.Hunt has moved to silver Zero Coat Sapim spokes and nipples, which reduce environmental impact over the more usual black anodised components. The alloy rimmed wheels swap alloy nipples for brass, which is naturally corrosion resistant.Hunt is aiming for accreditation by the Science Based Targets Initiative, which helps companies to measure their emissions and set reduction targets. It plans to produce an emissions statement and publish its progress in reducing emissions by the end of 2024, with the target of reducing its own emissions by 50% or more by 2030. Its aiming for net zero across its entire supply, production and waste disposal chain by 2050.It also runs RE:NEW, which offers a discount on low-use Hunt wheels. In addition, it says that it is committed to providing spares and replacement components for its entire range, so that riders can keep their current wheels running for longer.The Phase One in the wheelsets name points to Hunts goal of rolling out additional sustainability upgrades in the near future.Hunt Sustain wheelset options42 Carbon Disc Ti wheelsetDesigned for mixed surface riding, the 42 Carbon Disc Ti wheelset has a claimed 1,497g weight. Its rim incorporates 10% recycled carbon fibre content, sourced from aerospace and automotive components and waste from wheel rim production.The fibre is used to reinforce the outer rim and bead hooks, with Hunt saying that its multidirectional structure helps to improve the rims impact resistance.The rims are formed on a wax core mandrel, then resin is infused into the rim during moulding. This replaces the usual carbon fibre pre-preg sheets, which need to be refrigerated before use, thus reducing energy usage. The offcuts from Hunts production process are also easier to recycle than pre-preg. The wax core can be melted and reused more than 20 times, in contrast to the more frequently used EPS foam or silicone mandrels, which are single use.The 42 Carbon Disc Ti wheelset rim has a hooked profile with 22mm internal width and Hunt says that its optimised for tyres from 25mm to 35mm wide.Theres a new titanium hub too, which is made in Belgium and incorporates a stainless steel ratchet with 10-degree engagement. Spokes are Sapim CX-Ray triple butted aero stainless steel.The Hunt Sustain 42 Carbon Disc Ti wheelset is priced at 1,149 / $1,449 / 1,349.4 Season All-Road Disc wheelsetThe 4 Season wheelset has been a staple of Hunts range for years, but its rims are now made with 75% recycled aluminium. This is made up of 30% that comes from post-consumer waste including drinks cans, with the remaining 45% from industry including off-cuts and waste from CNC machining.The Sustain 4 Season All-Road Disc wheelset uses alloy hubs with 7.5-degree engagement machined in France alongside Sapim D-Light Zero Coat double-butted spokes and is assembled in France. Internal rim width is 23mm and claimed weight is 1,718g per wheelset. The 4 Season All-Road Disc wheelset is priced at 449 / $549 / 489.Finally, theres the Trail Wide 29 MTB wheelset. This uses similar construction to the 4 Season All-Road Disc wheels and runs on Boost hub spacing. Its priced at 489 / $589 / 549.Hunt isnt the only wheel maker to try to make its products more sustainable. A year ago, Chris King introduced the ARD44, a wheel which used a nylon matrix in place of the more usual epoxy to reduce energy input and waste in manufacturing and increase recyclability.Read how Shift Cycling Culture is aiming to make the bike industry more sustainable.

Gravel focus riders have patiently waited for the GRX Di2 groupset to be announced. After the successful reception of the GRX 12-speed mechanical group, the new Di2 version had high expectations. We were lucky to have some time to review the GRX Di2 12-Speed group on our home roads and gravel. It exceeded many expectations, but left us wanting in othersAll Photos: Jordan Villella/BikeRumorGRX-pectationsSome background on my GRX-perience: Ive been riding and racing the GRX 11-speed groupset for nearly three years, and its my go-to lever shape. I had the groupset on my cyclocross race/review bike (Canyon Inflite MVDP Edition), and it meshed perfectly with my fit setup and MTB style of riding. In fact, I liked the lever so much that I switched out the Ultegra 11-speed Di2 levers on my cyclocross race bikes to GRX Di2.That said, there are some improvements that I would love to see in the groupset, and upon receiving the updated GRX Di2 12-speed version, I was pleasantly surprised with what was updated and left wanting for others.If youre looking for all the technical details, check out our new piece about the GRX Di2 12-speed launch here.Out of the Box GRX Di2 12-SpeedWhen my review bike arrived, I first looked at the lever shape. For me, this is the most important touch point. The older shape enabled better hand placement for bike driving on technical terrain, and had a defined stop point to prevent slippage. Upon inspection and confirmation that the lever hadnt drastically changed, I started my build happily.Inspecting each piece as I reassembled my review bike, I noticed how much the Di2 GRX 12-speed resembled the mechanical version and how much was taken from Shimanos Di2 12-speed road line.Running through the gears and making sure all my shifting was dialed before my initial ride, it was notable that this group shifts quicker. The response time from push to rear derailleur is faster. This quickness is notable especially in the down shifts, with less clunk and more of a smooth feel. The changes to the groupset are subtle but effective to someone already immersed in the groupset functionality.Subtle Changes First Ride ImpressionsMy frame for the GRX Di2 12-speed review is the Specialized Crux, a bike I personally own and am very familiar with. This would give me the best experience and allow me to compare it to apples with a nearly identical setup from my personal bike.My inaugural ride on the new GRX was at my local gravel loop. Its pretty much a buffet of small, large, and logging road style gravel. The ride starts on the road, and its a great way to feel out small changes and make adjustments before getting distracted by the good stuff. The first notable difference was how the lever paired to the Pro Discovery Bars. Shimano notes that the new lever design considers gravel-style bars. The flare on some dedicated gravel bars will mess with some classic lever setups, and some are incompatible. However, the feel of the new GRX levers paired with the Pro Discovery bar with a 12-deg flare adds foundation to the hand placement. The bars and lever make a slight curve and give a nice perch to the palm. The feeling is like youre resting your hands on the levers and not grasping them.From this point on the bars, its very easy to access the shift levers and the brakes using one finger. The shift buttons have also been slightly updated, going from a dotted or dimpled texture to a lined or hatched one. This update makes sense, when you push the textured lever, the hatching is towards the rider. This gives the shifting button some extra tooth to and prevents slippage. This extra grip will be especially nice if your levers are covered in mud. Plus, the hatches are easier to feel with thicker gloves.Lever Shape UpdateThe brake lever shape is boxier, and the same is said for the whole top of the lever. The design team opted for a quick and sharp point of stoppage for the lever, something that riders would not slip from. The result is a slightly wider, more pronounced lever with a highly aggressive bend in the brake lever blade. This updated blade feels more responsive, IMO, but that can also be a result of the updated brake calipers.While shifting and especially while climbing, the click-to-action response time is quicker. The gear ratios are enough to notice, thats a great gear for this hill, and when you shift under load, its not loud or clunky. Another small but powerful update to the GRX Di2 12-speed group is the smoothness that it shifts under load, both up and down the cassette.Shifting Under LoadWeve all been there, That hill is WAY steeper than it looked on the approach or an emergency little ring bailout. Ive done them all, and sometimes your components bail with you. That is not the case with the new GRX setup. I could bail from large to small under load and not drop a chain many times, and its no small jump. The same is said about super low cadence shifts, the shifting is spot on and expertly ramped for natural performance.Updated Brake Performance Brakewise, I always felt the GRX groupset had an advantage. The lever shape is enough to effortlessly perform one-finger braking, and the caliper responds quickly. The updated version has all of that and more. The power and modulation are better, and the effort needed to break is less. The lever pull is very natural, with a clear, clean feel while braking. The responsiveness reminds me slightly of when I first got the updated (1st edition) Shimano XT brakes. They changed how I rode. I could late brake more and trusted my scrub speed in the corners.When you combine the new, easier to use lever blade with the updated Shimano road caliper, the result is a clear-performing brake and rider confidence.Hittin SwitchesMy review ride came fully equipped with sprinter satellite pods, my first time experiencing them beyond a one-off ride. Im not a sprinter, and I always thought the buttons were easy to access from the drops. Thats not what Shimano was looking to showcase; however, they are looking to demonstrate that you can stay comfortably in the drops for long periods of time without unnatural hand movements to the lever.After spending time on long slogg-ish gravel roads, I could see what Shimano are doing. If youre in the drops churning away the watts, youre in the zone. Its nice to have a up/down that that only requires a little thumb movement to change the gear and keep churning. Im not saying these are necessary, but they are nice to have at that moment and are very easy to install with the wireless levers.These auxiliary buttons are great if youre comfortable in the drops and a long headwind sector or slog. They are a luxury (meaning they cost slightly more), but they are also pretty cool. If youre a rider who spends lots of time in the drops, they are worth exploring.What Did Shimano Miss? The crankset for the GRX Di2 12-Speed isnt a grand update its actually a carry over. Its like, why fix something that isnt broken? I get that 100%. But I would have liked to see a clear 1X option. Riders (especially for gravel and cyclocross) love the utility and minimalism of a single ring option. I have a suspicion that we may see something for the 1X rider near cyclocross season, or maybe its wishful thinking. Either way, a one by option would have made this a compete offering IMO.The other is a power meter. Yes, we know that there are other power options out there. But with Stages out of the game and riders like to be matchy-matchy, why not offer a GRX power option?The other side of the argument (which I get), is there are many options for riders looking for power calculation, and power meter pedals are getting lighter and more affordable. So leave the power meter options to the power specialists.GRX Di2 12-Speed Lasting ImpressionsAfter less than a week on our new GRX Di2 12-speed review ride, I have many impressions, mostly positive. Im impressed by what minor thoughtful updates can offer to a component set that I deemed very refined.The pricing structure is competitive. Its refreshing that the new GRX 12-speedgroup is set nearly (within $50) at the same price as the 11-speed electronic version.My initial thoughts in a nutshell: I like this groupset a lot. I like how it performs, including the wireless front end, the shifting speed, and everything else. But it hasnt even been a week, so look for a long-term review. I see myself putting it through the paces, especially at Grinduro PA next month. Look for a full GRX 11-Speed VS 12-Speed comparison this summer.The post First Ride Review: Shimano GRX Di2 12-Speed Offers Simple Effective Updates appeared first on Bikerumor.
