Pros & Cons
Pros & Cons
- Cassette shifts fast and smoothly due to its precision design.
- The first 6 teeth rest on spiders, preventing the cassette from chipping your body.
- Thanks to the special coating, this cassette will last longer than lower end Shimano cassettes.
- Light materials and the use of spiders result in a very low weight!

Description
Description
Show allThe Shimano Ultegra R8000 and HG800 has been given an even better design. Shimano has managed to shave off a little more weight, give the cassette a slightly better finish to go with the increasingly fluent shifting motion, and improve the overal durability of the cassette compared to its predecessor. Various cassette ratios are available, enabling you to adapt to whatever terrain you're taking on. Most cassettes building up to a maximum of 23T or 25T are used on the flats or slightly rolling roads. The 28T cassette is ideal for hills, while the 30T, 32T and 34T (HG800) are ideal for the high mountains. Naturally, you have to take into account whether you're running double, semi-compact, or compact chainrings.

Fantastic product & fast service from Mantel
Gives you all the range you need when the road points up. Super smooth shifts and no need to be riding around with a 28 as the largest sprocket anymore. If you have standard Ultegra r8000 rear derailleur that should be fine, just new chain only.
Pros
- Range
- Great shifts
