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 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.

Durable, light, crisp shifting
A durable, lightweight option from Shimano. The Ultegra cassette can handle the slop of cyclocross and the long miles on the road. The 11-28 option is very practical.

The only caveat? The cogs are sandblasted to a matte finish. Unlike with SRAM options that are slick steel, grease and grime works itself into the finish making it very difficult to get the cassette to appear clean, even when it is. This is just a minor aesthetic complaint, though.

BEST USES: Cyclocross, Road Biking

Great cassette & experience w/ Jenson
I use this cassette (Ultegra 6700, 12-23, 10 spd) for my 7900 Dura-Ace equipped bike. The price is much better for the Ultegra vs. the Dura-Ace, which lets me replace it when required, not just when I can afford it (i.e., can't afford the Dura-Ace). The weight difference vs. the Dura-Ace is not really an issue (let's face it, we all carry a gram or two on our backsides or in our pockets !

Durable Cassette
Keeping this cassette clean and the chain lubed I have gotten good life from Ultegra cassettes. A little lighter than a 105 and similar useful life.

Excellent Price
Replaced an Dura Ace 11-25 with this Ultegra 11-28. Performance is just as good. What a big difference when climbing steep roads! Ordered it Monday, received it Wednesday, and went a personal best on a hill climb on Thursday. Plus, the price is great!

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.
