I was using the same 8-speed grip shift shifters since 1994. They were finally starting to feel a bit worn, so I recently replaced them with new SRAM Attack grip shifters. The Attack have a different feel. The old grip shifts just had a quick and positive click when downshifting, and felt like it went beyond the shift point slightly and then fell back into the detent. The Attacks feel like you're twisting against a spring then they pop into the detent. They shift fine, but the Attacks feel like they require more effort and are slower if you want to quickly downshift a handful of gears. (I realize that I'm also comparing well-worn 17 year old shifters to new ones.)

I was wondering how X0 twist shifters compare in feel. Do they feel like the Attack shifters? I am considering upgrading from 8-speed to a 9-speed drivetrain, and I was wondering what I'd get with the high-end twist shifters.

SRAM Grip Shifts changed around 2000 and started to use a Spool Release system that literally pushes the cable out. They acquired this when they acquired the bicycle division of Sachs.

While they feel different, they actually shift better and faster. As far as Attack vs XO, the Shimano compatible Grip Shifters have a shorter throw because of the higher pull ratio of the Shimano rear derailleurs than the XO/X9/X7 (all the same shifter, just different graphics and grips).

Thanks for the info.
So, that spool release system also applies to the Attack twist shifters?

I don't think I want longer throw so I'll stick with my old 8-speed stuff for now. The only problem is finding higher end (XT or XTR level) 8-speed cassettes.

Yes, Attack as well. You might look on E-bay if you like the old style...for example
