 Almost perfect, but could be stronger if it didn't have holes, August 26, 2010
By Christian Seier Blackburn (Sacramento, CA USA)
|
|
I have an REI Randonee touring bike that came with a Shimano Tiagra 9-speed gear set and chain. I upgraded to this cassette and a mid-range SRAM chain after stretching my chain and stripping 3 mid-range gears. I basically bought the cheapest new SRAM chain that was stainless. I can't believe they bother making a chain that isn't stainless. The new cassette and chain combination is way faster than the original. My only complaint is that I didn't see a SRAM option to have a cassette that doesn't have holes bored into it. I get that this is to conserve on weight, but I've been riding bikes long enough to know that light weight means ultimately more problematic and expensive, because I'll have to replace the part that much sooner. I mean seriously, those holes probably save no more than 60 grams, I'd rather have 60 additional grams of durability. Oh and the aesthetics of this cassette are great. In between each gear, is this almost metalic red stripe, that just makes it look awesome. Also, for anyone deciding between a 9 speed or 10 speed bike, 9 is the clear choice. You simply don't need 10 gears, there is after all 2-3 gears in the front of your bike on your crank. 10 speeds just means your cassettes and chains are going to wear out about 1.5 times as fast.

 Wore out way faster than OEM, November 18, 2010
By illegallydead (Golden, CO USA)
|

When I first used this to replace my original cassette, it worked nice, great even. Shifted really nice, good overall performance.
Now here we are today, a little over a year since I bought it. The thing is skipping/just not grabbing the chain. The teeth, while looking mostly OK, just aren't cutting it. This is maybe 800-900 miles in, 700+ of which are simple pedaling around campus. Whatever came with the bike lasted easily 2-3X as long, and with just the same amount of use/abuse.
So, at least for me, this does not meet my expectations of durability. It rides well and performs great for everything I used it for, up until not, which included campus/general commuting, plus a full ride of the Kokpelli trail.
Overall, I would recommend this, performance wise, and you really can't beat ~$30 for a cassette, but just don't kid yourself that it will last all that long.

Drop in OEM replacement cassette., December 28, 2011
By Maximus Decimus Meridius (Los Angeles, CA)
|
|
This replaced my OEM worn out cassette on my Gary Fisher Paragon. I had no problems with installation or use. Actually after I replaced the cassette, I found out I also needed the deraleur pulleys, new chain, and the front chain ring. If you have put on many miles you probably should do a complete drive chain rebuild.

 Great cassette, November 5, 2011
By Software Craftsman (VA)

Time will tell if how well it performs but over last several hundred miles it has been excellent. Here's the thing many people don't realize: You have to replace the chain with the cassette at the same time (assuming the chain is equally worn). Otherwise you can expect a lot of chain popping. Likewise, you can't put a new chain on an old cassette. I rode my original cassette for about 2000 miles and would have kept riding it except the chain had broken too many times and could not be shortened any more.

Quick Service, July 22, 2011
By Rich (Long Island, NY)
|
|
The part arrived about two days after placing the order. I believe it was shipped from California to NY, where I live. With the right tools and a smidgen of mechanical know how, the old unit was removed and the new one installed within 15 minutes. After about 500 miles,the unit is performing as expected. I don't anticipate I will need to replace it before another 12 thousand miles.

Seems as good as Shimano Tiagra, September 30, 2010
By Tom (Honolulu)
|
|
I pulled off my Tiagra 11-27 cassette and replaced it with this model 11-32. I also changed to a MTB rear derailleur. I thought shifting would suffer, but it works very smooth. I am very satisfied and the pricing is excellent.

sram cassette 970, July 13, 2010
By Billy Bob (California)
|
|
This appears to be a good value cassette. It is well machined and shifts smoothly. I'm not sure how long it will last/wear, but I hope it will last like a shimmano XT grade cassette.

 Piece, July 11, 2011
By Kirk McGurk
|
|
Skipped from day one on speeds 4,5,6,and 7. Yeah, I bought a new chain (KMC 9 speed) at the same time, so I know the chain is not the problem. My advice: save up and shell out the extra $40 or $50 for a semi- quality cassette.
Before I knew the skipping was so bad, I was climbing up a trail (alone) when the chain skipped and my foot flew off--I almost broke my ankle--not fun =(
