Replacement Cassette

[Dominican boy]

Im replacing my 990 Sram cassete. Which is better or cheaper if both for my Sram Hollowpin chain and Xtr Hollowtech crank?
I like the "smoothness" of the sram im replacing.

I'd probably change the chain and cassette at the same time. If you just change the cassette you might have some skipping or trouble shifting due to wear on the chain. Stick with what you like and works for you. I use lx cassettes as they seem to take more time to wear out. I use sram chains and they work great with shimano stuff.

lx cassettes
Yeah, don't spend a lot of money on cassettes or bottom brackets. Cheaper the better. Doesn't matter for speed, and the cheap ones last longer. SRAM chains are great. Change them both at the same time, like jj said.

I sorta second that. I dont brake the bank on my cassettes, bottom brackets, or chains. However, there is a point where I look at quality and weight differences. I have an XT Cassette, Race face ISIS bottom bracket, LX chains typically.

If you have a chain-stretch checker, you can monitor your chain wear and replace it before it starts to affect your cassette and chainrings and even your derailleur pulleys. Those XTR rings are expensive, and so are lightweight cassettes, so if you replace your chain often (regardless of which one you use) you can actually run really nice stuff for a really long time with no problems.

Personally, I run XT cassettes, since they're pretty light and half the price of XTR. I like the way the gear ratios ramp up in the shimano stuff better (less progressive/more linear throughout the gear selection). The new SRAM stuff looks sweet, so I might try those when they're available. I also use shimano chains, with whipperman connex links so I can easily remove the chain without tools (unlike the SRAM Powerlink, which is a pain when dirty). I reuse the master link for three chains. I haven't had significant wear on my drivetrain since I started switching chains often.

Regardless of what you choose, you should ALWAYS use a new chain when you replace a cassette- running an old stretched chain will only wear your new cassette quicker.

Caveat: Just be careful in really nasty conditions- improperly lubed, any chain/cassette/ring combination can be ruined in as little as a single race/ride if the mud and grit are bad enough. Make sure you clean often and keep everything well lubed with the right lube for the conditions- wet for mud, dry for most dry conditions, wax for super dry. And check the chain for wear often. You may spend more on chains at first, but you'll save money in the long run because the rest of your drivetrain will last way longer.

Gracias a todos..

I will replace cassete and get shimano chains next time for they are cheaper.
