Liked on YouTube: TUFF Carbon Fiber Road Bike Wheels Launch

TUFF Carbon Fiber Road Bike Wheels Launch
road bike wheels www.tuffcycle.com TUFF wheels have appeared in my previous video about my Ti road bike, and a lot of people wanted to know about them. I have been a "technical adviser" while getting the brand up and running. The store is now up and running, launching first with a range of carbon fiber road bike wheels starting from $935 with a number of option hubs, rim depths from 30 to 88mm, and tubular or clinchers. Future plans include MTB wheels in the not to distant future, and also road disc wheels. We are also looking into carbon fiber road and MTB frames. I plan on getting a set with the TUFF magnetic hubs. They have a drive engagement system like the more expensive DT hubs, but have the 2:1 spoke pattern on the rear wheels. This means there are 16 spokes on the drive side, and only 8 very widely spaced spokes on the left. The drive side spokes are most heavily loaded due to pedaling loads, but also the lack of dish to make way for all the gears on the cassette means the spokes on the drive side tend to fail before the NDS. 2:1 spoke designs have been popular on Campagnolo wheels for years, and now also being used by Shimano - these two are leaders in prebuilt wheels, but with the lower spoke counts they still tend to be a bit too fragile for big riders. But combining deep rims, and 16:8 rear spokes (Campagnolo and Shimano are only 14:7) TUFF wheels should be much stiffer and more durable than the Campagnolo Zonda wheels I had years ago (and loved - until the spokes started breaking and the rims cracked around the spoke holes) Carbon Clinchers are not that Clydesdale friendly, specially if you ride in the wet at all, or in very hilly terrain. The issue is braking on carbon rims. Standard road bike brakes on wet carbon rims results in very low power braking ability, which is an even bigger issue for Clydesdale sized riders. Also heat build up in the rim can be an issue on big descents because the resin doesn't transfer heat away from the brake track well. Heavy riders have to brake harder, and hence build more heat in the rim. If either of these two situations apply to you, I strong suggest buying a disc brake equipped road bike for the superior consistent braking in all weather and on big descents, then wait until the TUFF carbon rimed disc wheels are released later int he year. When I get my TUFF carbon clinchers (for use on flatter rides and dry conditions....) I'll do more of a review and put something on the blog as well
