the shifters. not all sram derailleurs are compatible with shimano
shifters (most aren't). the sram standard pulls a different amount of
cable with each 'click'. sram also makes some trigger style shifters.

so, be careful what you try to swap.

how long is the grip-shift grip? if it's the long style, comparable to a
handlebar grip in length, then you can cut it down so that less of your
hand is resting on the grip. if it's the short style, maybe you can get
used to resting your hand on the grip instead of the shifter.

i don't know if the disc cables pull a different amount of cable or not,
but it's something you really would want to know.

I just bought a Mongoose Tech-4 (I know) and really like the bike with
the exception of the shifter setup. It has the S-RAM grip shifters and
are really annoying. The system is much better and smoother than the
setup on my Nishiki, but are too easy to accidentally change when
off-roading.

I want to upgrade to the Deore Rapid-fire setup, but not sure what to
get. It seems most everything out there is for 9x3 setups. I have 8x3
gearing with a front disc and rear V-brake.

What is the difference between a brake lever for V-brake and one with
disc? It is a cable-actuated caliper, so I don't understand what the
difference is other than maybe the leverage.

I have found a few setups on Ebay, but they seem to be for all V-brake
or all disc setups. Could someone point me in the right direction or to
a specific model?

Thanks,
Dave
