The FFWD Fast Forward F6R Wheels are 58mm deep and seemingly similar to the likes of some Zipp and HED sections though the scale is narrower.

FFWD calls its rim shape Darc, this is the narrowness from the inner spoke section to the braking surface, and claims to reduce wind drag.  The hubs are very smooth and sealed well; they are laced with the brilliant CX-Ray spokes from Sapim, these wheels are very straight, they performed well on climbs. On even the steeper climbs they don’t actually feel as heavy as they are, dealt well with the side winds an all round good ride.  RRP £1014.99.
