Customer Service and Ultegra Cassette
This high quality 11-28 cassette for hills shipped on time and arrived ahead of schedule, everything in place. The order process at Jenson was foolproof, and their system kept me informed of the order status the entire way through. Add to this the savings over the "other providers" and Jenson won me over. Looking forward to ordering again in the future.

Quality cog doesn't disappoint
Purchased this 11/28 cassette to complete a driveline upgrade and expand my gear choices. Mated to Ultegra 53/39 crank using a KMC ten-speed chain this is a perfect, quiet running set-up. Very happy with the shifting and performance. Remember to retorque after the first 30 miles as the cogs do move around after initial use.

Shimano Ultegra 6700 Cassette
I changed from a 12-25 to this 11-28 to improve my hill climbing ability and down hill speed. Best change I have made to my bike. Have a compact crank and it works great!

I went with the...
I went with the 11-28 to give me maximum ratio range. Shifts perfectly with my KMC chain and Dura-ace RD. Fully compatible with Dura-Ace 7800 shifters. I'm not a pro rider, so for me the weight wasn't an issue. I believe it was only 10-20g heavier than the older 9spd cassette I replaced, but who cares? New wheels on the way anyhow...

hard to beat ULTEGRA
the 11 - 28 cog set is fast becoming the regular gear combination for 10 speed. combine it with a compact crank and it is pretty much the go anywhere do it all gear range.
The only thing that would make it better is if it were more common in the 12 - 28 range - I dont use that 11 tooth ever and this would make it the perfect combination.

PROS: 28 tooth cog, Ultegra quality

CONS: 11 tooth cog

I replaced my old ultegra 10spd cassette
The Shimano Ultegra 10spd cassette is just what I needed. Steep hills in this area, plus aging, made for a wider range on a new cassette. The price point was excellent, too.

Always my first choice
Slowly adjusting to the current 11 speed trend (it'll be probably 13 speed before I'm completely done). Still got a collection of wheels with 10 speed hub bodies that I use on my bad weather bike and ultegra cassette is sure the way to go. Better shifting then 5700, way cheaper and much longer wearing then the 7900.

Great Value and Performance
Great value and performance. I went from a 12-27 to an 11-28. A little change made a lot of difference. It gives me all the performance I can stand. I've combined it with a short cage Dura Ace derailleur and Ultegra shifters and Ultegra chain. Works perfectly. If Ultegra cassettes are good enough for some TDF teams then they're good enough for me.

Could this cassette work with a saint derailleur for dh riding? If not, what would be the best 10 speed cassette for dh?
A shopper on Jun 12, 2017
BEST ANSWER: The Shimano Compatability Chart is online.

I believe you are asking about the RD-M820 (Saint Rear Derailleur) with a CS-6700 (Ultegra 6700 10 speed Cassette).
That appears to work based on the table. Any Shimano 10 speed RD will work with any 10 speed CS.
My Paramount has a Ultegra 26-11 ratio. Can I order a 28-11 and have the cassette still fit the chain and bike? Seems to me yes. But I would like to confirm. thx.
GHenne on Jun 10, 2016
BEST ANSWER: It would depend on your rear derailleur. Some derailleurs cannot accommodate a 28 tooth cog.
