CX70 Top-Pull Cyclocross Front Derailleur
Shimano CX70 front derailleurs are specifically designed to perform in the demanding conditions seen on the cyclocross course using compact chainring sizes - which means better shifting performance than you're used to using standard road front derailleurs. This means you''ll be better able to drop it down to the little ring to clean the hill the other guys have to run up and then kick it up in the big ring coming out of the corner to leave all the other guys in the dust.
- Precision shifting performance in muddy conditions
- Designed for compact double cranks
- Compatible with Shimano 10spd chains/shifters
