It's been a great winter of riding the track at Boulder Indoor Cycling. The new Zinn magnesium track bike has really proven itself out there. They are so light, yet stiff, and super smooth. The magnesium frame corners on a rail and stays in control at very high speeds. Magnesium damps vibration better than any other frame material, which gives the rider much more confidence when riding really fast. Other frames send vibrations through to your body which means, you won't feel as comfortable at high speeds.
