The situation:

I have an ’04 Blur (XL) with an early ’04 Fox Float 100RL fork. I weigh 155lbs, and add another about 10-15 lbs with Camelback and stuff.

I have noticed that on my fork I am not getting my full travel, so I lowered the psi, but this increases my sag too much (at or above 25mm). I noticed pictures of me racing on this bike that even when I was not going through technical terrain, the fork seemed very “settled” into a lot of it’s travel. This is with the rebound set to full fast.

My question is (the first of a few): even though I may be using all my travel (zip tie indication), because of my excessive sag, effectively I’m only getting about 80mm or less of actual available travel when I’m on the trail. Does this sound right? I don’t notice my fork bottoming out, but I do notice that it doesn’t seem as plush as it should.

Possible solutions:

Is there a combination of air pressure and rebound that will yield all of or more travel than I am currently getting?

Could the 7wt. fork oil be too heavy and I need to go to a lighter (2.5 wt.) oil to get all the travel at the “normal” sag settings?

Possible alternatives:

Assuming for some reason on Fox forks because of my weight or whatever, I need to run more sag than normal to achieve the full travel, I was considering putting a Talas RL on the Blur. The thinking is: I could set the travel to more than 100mm (110 -115) and a low enough air pressure to get full travel, the additional travel would eat up the sag and leave me with effectively 100mm or “real” travel (which is what I am aiming for).

Does this make sense?

Fisrt I need to mention that I'm no Guru!

Second, I always considered that with any fork the last inch or so of travel was there for large impact and really agressive riding. If you bottom your fork every ride, you running it too soft. With air fork usually its pretty good when you run the recomended sag. Remember its not the amount of travel but the quality of travel that is important.

Btw I would advise you to run a bit more rebound damping than full open, you fork will jerk the handlebar less with some rebound, not too slow not too fast!

Good luck!

Thanks for the advice, sometimes I need to be reminded it's the quality not the amount.

I have been experimenting with different rebound settings, I think I'm about 4 clicks from full slow right now.
