Rated 4 out of 5 by Anonymous Durable but difficult fit
I purchased this to replace my alloy inner, which was ground down in a matter of months riding in the ever-present mud of upper Normandy. Durability is much better and it doesn't appear worn after several hundred km over the wet winter. However, I had a problem fitting it. If you look at the picture, you might notice the tabs around the holes that protrude toward the centre. On my bike (Lapierre Zesty 514) the inner ring has only a few mm of clearance as it rotates around the oversized (90mm) bottom bracket. I had to file down the tabs to make it fit. Probably not a problem for bikes with 68/73mm bottom brackets but a pain for me.
