Breathe life in to your older 10 spd wheel sets! *
The EDCO Ten-to-Eleven Locknut allows you to use our 11-speed Monoblock cassette on a 10-speed cassette body. **
The Ten-to-Eleven Locknut is available in two versions: 11t or 12t sprockets.
* Only use this locknut in combination with our one-piece Monoblock cassettes.
** Check your frame clearance first. You need an extra 1.85mm of space for Shimano. And 1.05mm for Campagnolo.
