Kreitler Poly-Lite Rollers

"The original roller company, Kreitler, has created this set of rollers to give you a little easier ride while still offering you all the benefits of training on rollers. The aluminum drums and polycarbonate end caps to keep the weight down providing you with a smooth road-like ride. As with all Kreitler rollers, folding is easy and no tools are required to adjust for wheelbase settings (31.5" to 46.75")."
