"i plain and simple think these are the best value/performance cassettes available at the moment... esspecially as Shimano have now gone to the funky chain/cassette combo and Ultegra is not as cross compatable as it used to be."
Pros: Durable, Great Value, High Quality, Lightweight
"For what this is this is a great product. No different to many FAR more expensive ones I've used in shops.
ONLY issue is that it has no "quick release" for the non turning side of the press. This means that the other side needs to be threaded all the way until it is flush - some models have a faster method of getting it there - but this is only an issue if you are using it alot. Not something that would concern me for the fortnightly/monthly use i'm likely to give it."
