Road    Chain Guides

N-Gear Jump Stop

The N-Gear Jump Stop chain guide is a clever device that prevents the chain from dropping when shifting to the small chainring. Just think of all the race mishaps and damaged to frames that could have been avoided with this simple device. Jump Stop allows the front derailleur to be set for maximum performance on downshifts without the worry of dropping the chain.
