Deore shifters for my new bike

[g***@yahoo.com]

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

re: 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.

Well, I did some more research. One, I kept thinking my derailleur is a
Shimano. But, the entire setup is all SRAM 4.0. So, that makes things a
little more difficult, unless I stay with SRAM. Maybe not a bad option?

Two, the entire Deore line is for 9 speed rears (ok, so I'm new to
this). The Alivio is one step below the Deore standard. Maybe only
because it is for 8 speed and not so much in quality? So, chances are
I'm going to need the derailleur as well. No biggie, unless I'm going
to need the cassette too. In which case, it seems I should have gotten
a different bike. It can be fun building them, but right now I just
want to ride the damn thing, not work on it all of the time.

Speaking of which, I could have gotten a Diamondback model with all of
the features I wanted including the Deore setup. I just didn't want to
spend the $439 even though it was on sale. I'm seeing now it would have
been worth it. But, would it have been a better purchase? It seemed
like a pretty nice bike.

Thanks,
Dave

get the equivilant sram rapid fire 8 speed shifters which should be
compatiable with your current system, much nicer than shimano, and
considerably cheaper than going the other route. you are looking at like
($50). or upgrade to 9 speed sram x.7 keep same der
