Very impressed

Very easy to fit and I've hammered it over the last few weeks (I'm a cycle courier) and it's doing a splendid job. Very good value for money.

Perfect fit replacement.

I replaced the rims on an older bike. Figured I'd do the chain and rear sprockets as well. Al of the new parts fit perfectly. Got the first bike done, decided to do the sprocket and chain of another. It went as well as the first.
