Shimano's Ultegra-level 10-speed features trickle-down technology from their 10-speed Dura-Ace 7900 group, and is a great choice for those looking to save a little cash without sacrificing performance or adding too much weight. Shimano's tight manufacturing tolerances allow for a strong and quick-shifting cassette, with revised ramps for higher performance than previous versions, even under load. Machined holes in the larger cogs help reduce weight, and the last three cogs are held together with a lightweight alloy carrier.

Compatible with Shimano and SRAM 10-speed systems. Weight: 236 grams (12/25). Available gearing options:

  • 11/23 Tooth (11, 12, 13, 14, 15, 16, 17, 19, 21, 23)
  • 11/25 Tooth (11, 12, 13, 14, 15, 17, 19, 21, 23, 25)
  • 11/28 Tooth (11, 12, 13, 14, 15, 17, 19, 21, 24, 28)
  • 12/23 Tooth (12, 13, 14, 15, 16, 17, 18, 19, 21, 23)
  • 12/25 Tooth (12, 13, 14, 15, 16, 17, 19, 21, 23, 25)
  • 12/30 Tooth (12, 13, 14, 15, 17, 19, 21, 24, 27, 30)

Your bike probably has highlow rear cogs you don't use. Get a tighter cassette - awesome upgrade!

no problem, prompt delivery, good price and value
by Michael D

almost 1 oz lighter than previous version, so quite light. Dura Ace is a waste of money for 99% of riders in my opinion.

chose 11-28, versatile, no need to change to long cage derailleur, I use with compact in front (road bike) and mid in front (tri bike) hilly here and I am not young.

Solid Value, Great Quality
by IslandRider
Competitive Racer

If you can't spring for the ridiculously priced DA or SRAM Red cassettes, Ultegra offers great quality, reasonable weight and a wide variety of gear-size options for a very affordable price point. I own at least six of these cassettes, in various tooth sizes, and they just do what they need to. Before living in Maui, I raced CX every year in Oregon and used these cassettes in brutal conditions where they'd get completely abused, packed with mud and debris and forced to keep on going. After post-race clean up, they were good as new. Important to always grease the splines on the cassette body when installing to extend the lifespan of both cassette and cassette body.

I was looking for one more lower gear for hills and this did exactly what I needed. As usual Shimano parts work great.

When the road bike had about 16,000 miles on it, the shifting started becoming erratic. The chain would jump between gears on the rear cassette, and cleaning and carefully adjusting the rear deraileur didn't help. I replaced the cassette, the chain (which only had about 4000 miles on it), and the shifter cable, all at the same time. Now the shifting works fine, but I'll never know if it was the cassette, the chain, or the cable that fixed the problem. The cassette is well made and easy to install if you have the right cassette tool and chain whip, otherwise it would be very challenging. The next time I encounter shifting problems, I'll start by just replacing the cable before replacing the more expensive parts.
