Rated 5 out of 5 by Anonymous Mavic Spacer M40417
The description is not correct. This is a 1.75mm spacer to allow Shimano 8,9 or 10 speed cassette to be installed on an Mavic M10 freehub as found on aksium, ksyruim, cosmics etc. It is the genuine Mavic part number M40417 and does exactly what I needed it for.
Note if using a 10 speed shimano cassette you also need the 1mm spacer that came with the cassette. If 8/9 speed no 1mm shimano spacer is needed.
The parts are installed with mavic 1.75mm spacer first, then shimano 1mm spacer on 10 speed systems, then cassette.

Rated 5 out of 5 by Anonymous Very handy and used more often than you'd think!
This item came with a set of Mavic Crossride wheels I upgraded one of my bike with. On reading the instructions it looks like it says it's not needed with a 8/9 speed cassette but without it my SRAM PG970 was flapping about all over the place. Once I fitted this ring it was all good and everything was tight and solid.

Fitted to a Mavic Crossride wheel this solved the problem of a loose cassette, my 9 speed Shimano SLX cassette was loose and although a plastic spacer worked for a while it soon cracked and became loose again. this spacer fits perfectly over the feehub before putting on the casstte and everthing tightens up nicely.

Simple - You cant fit an 8spd cassette to a 9/10 speed hub without one of these aluminium rings. If like me you live in the past and want or need to run an 8spd cassette - you are gonna need one of these if you actually want to tighten it all up!

These are normally used singly but I bought three so that I could use a 7 speed cassette on the 9/10 speed hub that came on my lovely new wheels. This is until I get round to upgrading to a 9 or 10 speed shift system. They have done the job perfectly so far (and they've been on for a few months with a fair bit of XC riding).
