I could not find a road cassette to meet my needs so I bought this MTB cassette for it's 11-28 gearing. My bike came with a 12-26 which is nice but I live in the foothills of the Smoky Mountains so it is half uphill no matter what unless you are beside a river or stream. The SRAM is lighter than my stock piece and is plated to prolong life. Awesome buy at a great price. (under 20)

This cassette is inexpensive, yet works wonderfully over lots of miles. I have 4,000 miles on one cassette, and bought another for my other road bike, which I have 1000 miles on. Shifts very smoothly, no complaints at all.

I purchased this cassette to replace a worn on on a used bike (2007 Specialized Rockhopper) I bought. No matter how much I adjusted the rear derailleur, I just couldn't get the chain to change gears quickly and smoothly. I suspected that the old cassette's teeth were worn, and it seems as if I was right...This cassette did the trick. Perfect, fast, smooth shifting. It's certainly not a light-weight, but for under $20, it definitely can't be beat.

If you've never changed a cassette before, and you're attempting this yourself, you'll have to have 2 tools in order to remove your old one - a Chain Whip, and a Cassette Lockring tool. Without these, it'll be very difficult (nearly impossible) to remove your old cassette. If you don't have a chain whip, do like I did, and make one using an old bike chain, and a piece of thin metal to be used as a handle.

Update (09/13/2011):
I removed the cassette because my rear hub was failing. Upon removal, I found the rivets holding the cogs together had failed. This isn't a big problem for me, it just slows down the process of swapping cassettes, or replacing them after cleaning. On a positive note, it makes it all that much easier to thoroughly clean each cog & spacer, making the cassette look like brand new every time.
