XLC Chain Guide CR-A19 - 31.8 mm

The CR-A19 chain guide from XLC is a high-quality chain guide that fits in the area where the front derailleur would be located on a double drivetrain. It is only compatible with seatposts that have a diameter of 31.8 mm or 34.9 mm.

It is only suitable for single chainrings, specifically 1x9, 1x10, and 1x11 systems. Chain guides are typically found on mountain bikes, as they prevent the chain from jumping off the chainring, which can happen on particularly rough terrain or when shifting gears. The CR-A19 is made of 6061-T6 aluminum, so you can be sure that it is not only lightweight but also very durable. This item is only available in black, but it fits many bikes.
