I won a pair of the FSA vision trimax wheels just over a year ago, and popped them on my training bike and they have seen about 4000 trouble free miles since. They seem pretty good all rounder, 1543 grams on my scales, pretty stiff, hold speed well and spin up quickly with good pick up. Mine are still running smooth and wobble free, so they have been pretty durable for me, but I am under 70kg. More impressive imo than the DT mon chasserals they replaced, and climb just aswell. I race on Reynolds 46’ss or mavic r-sys sl’s, so that’s my comparison. At their rrp I’m not sure what they would offer against their rivals at that price, but Planet x are selling them at half price at the moment for £250, which makes them seem a positive bargain to me.
