I've had a SS I ride for about a year, I mix up riding the SS with rides on my Rush. I've always wondered how a geared hardtail would ride. I finally got one this week, C-dale Caffeine F2. Got it setup and stole the wheels off my Rush (I'm building identical wheels for the hardtail). Rode 2 laps at Carter last night and got 10 miles at Alafia this morning. WOW. Now I know why racers all ride hardtails. I kinda knew what to expect with having the SS, but this bike is a rocket! The Rush is no slouch when it comes to pedaling, but a hardtail is so efficient. Unreal. If you haven't tried it I recommend giving it a try.
