would a 9 speed shifter work for an 8 speed?

Like the title says. I have gripshift on my bike right now and I loved it until I tried rapidfire... which is beautiful and it seems like everyone only carries 9 spd. rapids.

www.bikeroom.com still has a full contingent of 8 spd parts in the xt class...in the states call airbomb as they are the same company you should be able to get them.

You could always upgrade to 9sp, if youre rear and front derailleur are 9sp compatible just replace shifters and cassette.

Before you go rapidfire I'd recommend having a look at the SRAM triggers, I've only had mine on for 24hrs but initial impressions are good.

The index spacing in the shifter on either a 9 speed rapidfire or Grip Shift is smaller than 8 therefore it does not work that well. However most any LBS can get 8 speed stuff easily.

Let's not forget to mention that the leverage ratio is different for a Sram (or ESP) derailleur. IOW, you can't use a Sram rear derailleur with an XT shifter or vice versa.

Sram however DOES make a grip shifter that IS compatible with Shimano.

The new SRAM triggers come in both SRAM compatible X7/X9 and Attack which are Shimano compatible. As far as I know though they are only 9spd. Gripshift is still available in 8.
