Premium Rainbow Cassette & Chain
Superb quality and very good weight for a 11-32. I already have a 11-28 from the same seller on another bike, and the operation of the change is perfect. The colors do not disappear with the passage of the kilometers (I have a 9-46 of 11v in the MTB, also of ZTTO which is another wonder). I recommend using a good chain. Personally, I love the SUMC in rainbow finish. They facilitate a super smooth and effective transition, are light and keep transmission clean. Infinitely better than the original Ultegra chains on the road.
Fantastic quality. Soft and precise change. Weight savings. You can't ask for more than durability, and that's all there is to do is make miles. Fast shipping and well packaged. Everything is perfect.
