Familiarity: I've used it once or twice and have initial impressions
Installed them before a big trip... and so glad I did. It's amazing how smooth shifting makes the ride so much more enjoyable. You know your derailuer is dialed but still having shifting problems? Install these bad boys and enjoy the ride.
