high, you'll unnecessarily lose momentum. Attack the bottom of the rollers at the same intensity as on the flats -- but gradually increase the effort as you ascend. The ensuing descend lets you recover while maintaining speed. Keep your hands on the hoods just as you would on the flats. Remain seated until your cadence drops by about 5rpm, then stand; don't shift until your standing rpm drops by about another 5rpm. Extra Credits -- Training? Use rollers as unstructured intervals. Pushing to the limit on one roller only to have to recover quickly for another will give you the ability to respond to attacks or put in your own double kick. Climb in the Pack - 1. If you are a weak climber, start at the front of the pack and gradually drift back, so even as you loose ground you maintain contact with the group. This is more efficient than chasing from the back. 2. If it's a competitive ride, don't get boxed in on the shoulder. And the shorter the hill, the harder you should work to keep an attacker's wheel. Or discourage attacks by setting a high tempo. 3. If you get gapped, keep your tempo steady. The pace up front might moderate, allowing you to catch back on. 4. Watch other rider' from. Jerky pedal strokes, hunched bodies and other signs of deteriorating technique tell you they are tired.
