Breathe Life Into Your Older Wheel Sets!
Mount 11- or 12-speed EDCO Monoblocks on 10spd freehubs (HG 8-9-10 body).
Works ONLY with Monoblock cassettes!
The unique one-piece design of the Monoblock cassette allows the smallest cog on the cassette to sit further outboard from the freehub body. The longer thread on this 10+11 lockring reaches the 10spd freehub easily.
