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.
Very Happy my order from Western Bike Works.... It's very important to maintain a clean cassette and to ensure the chain is not stretched out. Buy the tool and check the chain regularly. With the Shimano Ultergra cassette and a new Ultergra chain, I feel faster then ever before.
I love my Cannondale Evo that I purchased from Western about 5 years ago. With almost 20k on it, I go through cassettes and chains ... occasionally. I LOVE my Sram RED components, but for economic & convenience reasons I use a Shimano (6700) cassette, mated with a Sram chain. The marriage is good smooth shifting, quiet, efficient, and the gear options meet my needs. Western Bike Works' prices are excellent, and their service and advice are outstanding! Manager Seth is extremely knowledgeable, helpful and kind. He goes the extra mile to advise on tasks I'm capable of, and to do great work on tasks I need accomplished in the shop.
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.
Finally gearing that is intermediate between Mountain and race. The 12-30 10 speed is perfect on my cross bike for some serious off road and touring rides. Shimano quality is also a big plus - quick shifting and durability is a given. I bought the cassette for a loaded tour and now use it to take on local MTB trails. It has made the cross bike more versatile and fun. I would recommended for adventure rides, steep road climbs and tours!
