Product information "FREESOLO-BB-38"
The Freesolo V2 chain guide with its wide range of applications from CC, to Enduro and DH, is a true all-rounder and still the lightest and fully adjustable chain guide on the market. This version can also be mounted on bikes without chain guide mounting options by using the bottom bracket clamp. The CNC milled scale makes it easy to adjust the chainring size, and the adjustment of the chain lines is done with a table and spacers. The "Front Flip Technology" allows you to remove the chain without tools in case of an incident on the trail, or to pull off the crank from the bottom bracket during service without having to disassemble the chain guide. The versions marked with the 38 have a chainring adjustment range of 28-38 teeth.
