We start with a tough, durable no-nonsense unit from Microshift that works as well as any, but then set about making it better. Derailleur is disassembled and chain tension spring is adjusted to provide 25% more force. This provides a big advantage in keeping the chain planted on your chaining when the course gets rough or mud build up might lift another bikes chain off the chainring. Next we pack the units with good quality grease from the folks at Phil Wood and then we replace the pulleys.
Pulleys Matter... Shimano compatible derailleurs optimized for the mud and abuse of Cyclocross. Solid and proven mechanism with 25% higher chain tension to better hold chain in place for off road riding. Assembled with Phil Wood Grease and offered in three pulley options:
