The new 105 cassette and chain replaced my Ultegra set, but the feel and look are much better. The cassette is light weight and smooth, as is the chain. But the bonus for me was that the chain has hollow cut links, making it lighter than my old chain. It is direction specific, much like a tire, you have to fit it to roll right. Unbeatable price, sweet..
Great value! Installation was quick and simple. I've used the same chain and cassette before, great combination. Wasn't looking for anything else, Happy with the purchase.
This part was up to the usual shimano 105 standard, a very high one. I was upgrading to a 53/39t chainset with this and this fit the bill perfectly. The part is strong, light and durable!
I paired this with a new 105 chain and 105 11/28t cassette for a faultless drive train. I have used this for a few hundred miles now and it's running smoothly and has suffered zero issues.
It also helped that the part was on a great deal and posted promptly.
Packaging and postage were exemplary and would happily return to Merlins Cycles again based on this service.
