For most of us who don't live in a tropical climate, spring racing means a winter spent slugging out miles in the living room. The CycleOps Fluid 2 Winter Training Kit can't melt the snow, but it does minimize the sting of staying indoors and provides everything you'll need to get the most out of those hours. The bulk of this kit is the Fluid 2 trainer, which gives more resistance as the pedals spin faster for a resistance range from 20 watts up to 725 watts. This means that this one little trainer has a resistance range that accommodates everything from a recovery spin to short, hard interval efforts. With a wide, two inch roller, the Fluid 2 also gives a smoother ride with less tire wear than trainers with a smaller roller. It features a wide base for stability and a simple yet secure locking system to hold your bike firmly in place even when you jump out of the saddle to sprint. The CycleOps Fluid 2 Winter Training Kit comes complete with the Fluid 2 trainer, two climbing blocks no more propping up your front wheel with old textbooks, a trainer mat to protect your floor, and a sweat guard to protect your bike. It will accommodate tires from 26in to 29in with rear spacing of 120mm, 130mm, and 135mm.
