Hi I am new here.

I just got the 2001 GT Avalanche 1.0 equiped with Judy XC fork. The current adjustment is too soft for me, so does anyone know which direction should I adjust to make it tighter?

Is there any procedure that I must follow to do this, like release it totally before tightening it or something like that?

Thanx!!!

If you turn the knobs clockwise it will increase spring pressure making it stiffer. If it's new I would turn them all the down, (clockwise), then back them out an equal number of turns so they are even. If you go to Rockshox site they have a manual for your fork with instructions for setting up sag.

RockShox considers 1 inch of depression correct with you on the bike. If you find that after adjustment you still have more than 1 inch of sag/depression you will need a heavier spring set. The stock spring set will be too soft for a Clydesdale class rider.

RS should have their chart of springs vs. weight up on their website. It is included in the Judy manual I have. If you need it and don't find it post back here and I can give you the weight ranges for the different springs on the Judy.

Thanx!

I have tried tighten it to the fullest but it doesn't seem to feel any different.

unrelated,
The stock springs are in the middle of the weight range. There are three models of springs available - light, medium(stock), and heavy. You will need to go with the heavier spring set to make them stiffer.

You can check some of the online retailers to get an idea on pricing. That is a simple upgrade as long as you have a large enough wrench or socket to remove the nuts on top of the shock. My Judy has 24mm nuts.

Thanx!

What do you mean by the "top" of the suspension? The axel that is fitted into the frame or the "top" where I can adjust the suspension?

Where you adjust the suspension. The nut right below the adjuster knob.

Hi...

If I keep turning and turning the top knob but feels no stop, does it mean I've broken something???
(I've been turning like 40 turns)

Is it hard to replace?

If you keep turning and turning your pre-load adjusters and it never stops in either directions, you have the same problem that I have. It seems my pre-load adjusters (both) are stripped.

I would like my fork to be a little stiffer too. I have decided on getting a new fork anyway (right now I have Judy XC 2001) but to remedy the problem I will get a heavier spring. I haven't checked prices however I believe it will be cheaper than replacing the pre-load adjusters.

You should be avle to get the top adjuster knobs. As far as springs, go to your LBS and order the heavier springs. As far a ssag goes for a 63mm travel setup the sag is 7-15 mm. For a 80mm setup, the sag is 13-20mm. For the 100mm setup, the sag is 18-25mm. If you got the bike new from your LBS the fork should be a warranty issue. If it is used it will be your money and time. Fixing the problem is no big deal.
