Great entry level wheelset for any beginner to fixed gear bikes. Comes with 100mm spaced front wheel, and a 120mm rear that can be spaced to 126mm and 130mm as well. Both wheels use Formula high flange sealed bearings and Weinmann DP18 high profile rims. The rear is a “flip flop” with fixed on both sides, this gives you the ability to have a different ratio on either side, or even a freewheel on the opposite side. Comes in green, black, white, red, yellow, gold, blue, and silver all with black spokes and hub and a non-machined sidewall (call for MSW).
