- The Echo TR freewheel is one of the most popular and maintenance-free freewheels on the market.
- Uses 9 steel pawls to create 108 engagement points for super quick pedal response.
- Constructed from tough CroMo steel for maximum durability.
- Unique spring design provides reliable engagement and gives it a loud sound.
- Standard 1.37" x 24tpi thread fits all threaded trials cranks.
- Available in 18t only.
- Although a standard 4-Prong tool can be used to remove Echo freewheels, the Echo Freewheel tool fits much better and is easier to use.
