SRAM  PG-970 9-Speed Cassette

We bought this cassette, which is 11-34 range, to replace an 11-32 cassette. it was easy to install (using the SRAM casette tool, chain whip, and torque wrench, and works great. Very smooth shifting, and the new gear ratios fit our riding style (tandem touring, loaded) better.

I've had one of these on my 05 novara ponderosa ht commuter/tourer setup for two years and roughly 6500km. It could still be in decent shape, but my chain is just about fried and may have formed the cassette teeth too much to have it work with a new chain. In terms of drivetrain maintenance, I usually did moderate cleaning/lubing about every 200km and a thorough cleaning about every 500km. My primary use was commuting/errands/all around transport on city streets with a decent amount of loaded couple day tours here and there. Mixed amount of hills/flats, rain or shine, location sf bay area california. It shifted smoothly and I've had no problems with it. My previous cassettes I think were shimano deore or lx. The sram has lasted at least as long as my first cassette and 1000km+ longer than my second one. It's lighter than the deore for just a little more $. I know you can get a lot more milage out of a drivetrain than this for more $$ (my friend has put 15-30,000km on his drivetrains doing touring/transport with minimal cleaning), but it has served me well for this price.

Started using these in place of a shimano cassette on my hard tail, amazing, it’s a world of difference, granted my shimanos were so old it really couldn’t compare but if you are looking to stretch the life outta your hard tail buy this cassette, I have hit black trails with no issues and the only play is with my derailleur, solid price, solid quality and local pickup!

Pretty much a standard gear cluster for riding the East Bay Hills.
