I am still running 10 speed. Needed a new cassette for a new Hed wheel. For $XX, these are incredible deal! The finish holds up really well, too. Seems to be more durable than Dura Ace for a lot less $ and just a little more weight.
Bought this Ultegra cassette to go wih my new wheelset. I concur with claim that is better shifting. It is very smooth and precise.
Also, enjoying the new wheelset. They are lighter than my old Mavic wheels. They roll better, ride better and give me the option to go tubeless in future.
This was an upgrade to make the hills a little easier. Not surprisingly, it was an easy fit to replace the existing Shimano 10-speed cassette. The 30 tooth cog was one size larger than spec'ed by Shimano for my derailleur, but it shifts well and didn't require a modification of the chain. Easy and inexpensive upgrade.
Good product by Shimano. Still think price could be a little lower since they are mass produced. I do like the quality control though. Decent packaging. Product could come with an extra bottom spacer.
I've bought a couple of these now and they are pretty hard to kill. I couldn't justify replacing my cassette with the higher end ones that I seemed to kill very quickly. I put these on and honestly I don't notice any difference. They shift very well and have had pretty good longevity so far. I also have one on my cross rig and it has held up easily to a season of mud, dust, muck, and ice.
Like all race ready Shimano components, they work well flawlessly. This cassette is no exception. I purchased it to replace the same one I've had for the last six years. I put the old one on my second wheel.
This is a great option especially with the extended gearing range of the 12-30T cassette. I run it with a 105 rear derailleur (the newer 5701 series, short cage and older 105 derailleurs won't work) and it works great. It keeps humming along no matter what rain, mud and road salt I throw on it. Obviously you'll get the best results if you keep it clean.
I have a 10-speed road bike with Shimano Ultegra components. The cassette range was 12-25. Both my daughters live in areas that are quite hilly and I started to feel that I needed a little help every once in a while. I decided to try this Shimano Ultegra cassette with a range of 12-30. Switching the cassettes was no problem. Shifting is still perfect. I did not have to increase the chain length or purchase a long cage derailleur. Everything feels great. I sometimes miss the 16 tooth cog but it is not much of an adjustment to make for my pedaling ability. I am extremely happy with this purchase.
