D1x Electronic Shift System
The D1x Trail is a programmable wireless shifting system. The revolutionary technology behind the D1x transforms nearly any mechanical derailleur, of any speed from 2 to 20, into a high-performance electronic shifting machine. With a long battery life and an app for easy setup, the bike you rode today could be digitally tuned and shifting smooth tomorrow. —$389
Mountain Bike Action is a monthly magazine devoted to all things mountain biking (yes, that’s 12 times a year because we never take a month off of mountain biking). It has been around since 1986 and we’re still having fun.
