fork / shocks selection

hello, I'm looking to buy a new fork for my 1996 giamt mcm2 carbon mtb. it's got the original rockshox quadra 21r. I'm looking for something with more give, I suppose. I'm looking around and can't seem to find any with <= 80mm travel and cantilever / v-brake mounts, and 1-1/8 threadless mount. quadra 21r has 63mm of travel are I heard you aren't supposed to go 20 mm difference. budget is probably $100-200. I just had crankset and cassettes replaced, and brakes are shimano deore lx.

thanks

Finding an 80mm travel shock won't be too hard. Finding one with cantilever boss mounts that's higher end....... Others may add recommendations for a new fork. I'd search ebay and CL for a used early Fox. They made an 80mm travel that was mounted to Stumpjumpers. A lot of those have been replaced with 100mm travel forks. They had V's back then that use the same mounts so if you can find one, that might do it. As for new........

Yeah I would really rather not buy used parts.. Would a 100mm one be OK? What is the reasoning that it can't be > 20mm difference than normal?

It's a coil spring fork so depending on your weight you might need a different spring in it.

Travel be can reduced to 80mm by changing around an internal spacer.

That fork has adjustable preload, adjustable compression damping with lockout and adjustable rebound damping, the ABS+ compression damper on these forks is very good.

Look around you might be able to find one cheaper, be aware that some shops might be selling the disc brake version, this fork comes in 2 versions, disc brake or disc brake + v-brake.

No it's not 20mm difference, it's 37mm difference over the original shock on your bike. Just as important, a 100mm shock will be a 60% increase in the travel of the shock and raise the frame considerably. You can do it, but be aware it can change the geometry and handling of the bike. You can make the change to a 100mm fork, but just be aware it has the potential to change the ride and handling of your bike.

The 19 year old mountain bike you currently own is entirely comprised of used and outdated parts. The amount of travel in your current fork has been relegated to hybrid forks. Dampening technology has progressed to the point where 100mm is the standard your 63mm used to be.

If you're still committed to buying a new, unused fork, some newer Rockshox forks are able to have a 20mm reducer installed. Pair that with some NOS lowers with brake posts and you'll have yourself a $250 fork for the price of $400.

I would talk to a Rockshox dealer with a reliable mechanic in order to see if that is a reasonable course of action.
