thanks for that link Ray. Good reading to keep in context the physical limits of carbon rims. I've found it difficult to get beneath the marketing and industry hype about carbon products. Obviously wheel manufacturers are not interested in publishing the objective limitations of their products.
My goal is to keep using my Farsports 50mm cc's for all purposes (race, group, randonneur), and see how they wear. However, now, if I know I'm going to do a lot of descents, I'll ride alloy. I weigh 85, so I'd generate more brake heat than a sub 75kg guy on steeper descents.
Another reason why I like disc brakes on road bikes. I wouldn't have (and haven't) risked Chinese carbon clinchers with my road bike with rim brakes but I didn't have a problem getting some for my CX commuting bike with disc brakes because nothing is touching the rim during normal use. Not trying to turn this into a great brakes debate but disc brakes solve the primary problem with carbon wheels IMO (yes at the expense of weight but I think there are other advantages that make it worth it).
Farsports 29er wheels have covered another 50km to and from work. Keep in mind this is on a 12.5kg bike (empty) with some weight in a bag on the rear rack so the wheels are a little more loaded than usual and I ride roads at pretty good speeds. Bombed a hill at about 62kph on the way home today and braked into a roundabout at the bottom without fear, I took a speed hump at 50kph and rode over a fair bit of rough ground at 40+, no problems wheels feel nice and smooth.
