Crankbrothers believes that a front wheel should be more forgiving, as it is responsible for turning the bike and severe terrain deflections that could ruin steering feedback dynamics. Our passion is the products, technology and people that make them. CLICK HERE for more info.  The Santa Cruz Syndicate team has been helping us develop them and we sorta showed them at Eurobike. Cargo is generally in the back half of the velo, and there can be large cornering stresses on the rear wheel when the veo can hit 50+ on a downhill. I know this article is old, but the rolf Prima with 16/20 spokes gave me a good laugh. With our paired spoke technology we are able to built up to three times the tension in our spokes than a traditionally laced wheel. I started cycling when I was about 380lbs and I have damaged some wheel sets. While I was waiting on replacement rim, spokes, and nipples from Mavic for my Ksyriums, I picked up an inexpensive pair of Fulcrum Racing 7s. Time for new wheels, and I’m getting confused about where to go. High-end downhill wheels with the trail cred to match, Weight: 1587g | Material: Carbon | Rim width (internal): 22, 25, 27, 30, 31, 37mm (depending on size) | Spoke count: 28 | Tire options: Tubeless ready, clincher (29er or 650b) | Hubs: DT350, I9 Torch or Chris King | Boost spacing: Yes, Santa Cruz’s Reserve DH 29er wheels are downhill-specific carbon hoops designed to withstand the abuse and impacts of modern downhill courses.Â. Rim widths differ vastly between cross-country, downhill and enduro wheels with profiles ranging from 23mm to 35mm. Durability and easy to replace WHEN it breaks are the priority, not weight nor “looks expensive”. I know some people say that carbon frames are bad for touring because they can’t be repaired, but unless you’re deep into the third world, are you really going to have your touring bike repaired during your tour if the frame fails? If a wheel starts with higher tensions you do not stress these parts as much in the fluctuation of tension as the rim rotates. How would pairing spokes make it stronger? I am riding on RS80s at my 270 pounds of pure power. Despite its downhill bent, the Reserve DH rim profile features a combination of stiffness and compliance. A big drawcard with these particular wheels is the Hydra freehub — offering 690 points of engagement, power delivery is immediate. So, I’ve worn out the shimano wheels that came with my bike. This is not meant to be a disparaging comment about Mavic but a comment that high spoke count wheels are worth nothing if they are not properly built and tensioned. The wheel had not lost any more trueness. Hooray for cycling. Double butted spokes are plenty adequate for most application, though our hubs are compatible with some thicker gauge or triple butted spokes, if someone desires. Please refresh the page and try again. 3 To combat these tricky features, the XXX hoops have been built using Trek’s very own OCLV carbon fiber and laced to DT Swiss 240 hubs, while a generous 29mm inner rim width ensures riders can run lower pressures for better traction and comfort. I got two full years of riding and racing out of the first set that was built with the lighter ZTR 355 rims, not bad for a 29er wheelset that weighed around 1500g. The idea that carbon frames are disposable is more myth than reality. Road: 66 SLG or Strike/Assault mixed depth. But depending on how hard the guys ride, even our strongest wheel systems will have a finite lifespan. Now for some advice based on experience… As I said I am 431lbs and I ride 4/5 times a week in order to drop weight and it is working… so as I write this I a losing weight but my experience should still be pretty valid. If you have special weight requirements, there are some e-bike models that can withstand up to 550 pounds (250 kg). What this means is as the wheel rotates and comes in contact with the ground, each spoke is going from full tension to less or even a negative tension number, causing stress on the spoke, rim and hub flange. I am in the planning stage of designing a bicycle camper. I currently own several sets of wheels using Shimano and White Industry hubs. The Cross hubs (shown above) build great rim-brake touring wheels, with their symmetrical high flanges. My Yeti ASR7 came with Mavic Crossline, these were good but not perfect, needed alignment in various opportunities, now in my Ibis HD I asked to Universal Cycles assembly a pair of Stans Arch with Hope Evo hubs and Sapim CX spokes, these whells rocks and hold more hits than my last Crossline set in the same trails, I weight with gear @ 270lb so I can give a good comparisson from the Crossline to the Arch+Sapim+Hope set. Compared to other wheelsets in the segment, the CB7s utilize a 23mm internal rim width, not bad by modern standards but notably shy of the 30mm width offered by Bontrager’s Kovee XXX wheels. Our 58RSC and 38RSC have a carbon rim with alloy brake track and are very strong wheels, too, and work well for the heavier rider looking for something more aero. DT Swiss E 1900 Spline 30: £345; Mavic Deemaax Pro Sam Hill: £900 Arrived here looking for recommendations on a rim for a new rear 26″ wheel for a velomobile. This is one of more heavy-duty electric mountain bikes (eMTB) that falls in the mid-range of e-bicycles on the market. The Kovee XXX TLR 29er wheelset represents the lightest and stiffest offering in Bontrager’s cross-country range and is raced exclusively by Anton Cooper, Emily Batty and Jolanda Neff on the UCI MTB World Cup circuit. The only disadvantage other than high cost would possibly be long term durability. The weight penalty is more than offset by longevity when you’re a long ways from service or parts. what might be the reason for this. Unconventional approach to wheel design with noticeable advantages, Weight: 1,910g (29in), 1,875g (27.5in) | Material: Carbon | Rim width (internal): 30mm | Spoke count: 32 | Tire options: Tubeless ready, clincher (29er or 650b) | Hubs: Zipp ZM1 | Boost spacing: Yes, Wheel manufacturers are now understanding that despite a stiff wheel giving sharp cornering and acceleration, building compliance into a wheel allows better grip and control as the wheel can deform over rough terrain.Â, No manufacturer takes the concept of wheel compliance further than Zipp who has entered the mountain bike market for the first time with its 3Zero Moto wheelset. Nothing special, just 36 spoke with double wall rims. 1. Carbon rims have been proven to be more reliable and resilient than alloy rims on the downhill world cup circuit. The pair of Open Pros I have seem to have a flat spot around the weld and are the only box section rim I have ever owned that I had difficulty maintain roundness on when retruing. check latest price. I used solid, wide rims (like Mavic A719 or Velocity Dyad) and 36 hole, 3x lacing with double butted spokes. I’ve tried wheels on my road bike that have low spoke counts and my experience is they don’t last too long. Weighing just 1,350g for the pair, they're incredibly lightweight, yet surprisingly robust. Even with the best quality wheel build, the nicest spokes and the most solid hubs… rims can and do fail due to heavy loads, braking and harsh terrain. These custom carbon gravel and XC wheels are hand-built in Yorkshire, England. A good alternative is to look out for bikes for over 400 lbs or maybe some other form of equipment. This is a good combination but @ 431lbs I still buckle the wheels through potholes and driving hard up hills so I have two rear wheels and I swap them every month or so and get the used wheel trued and tensioned at my LBS.
