I've had my new bike (Marin Pine Mountain) for a couple months now and have ridden it hard. After taking quite a few 2+ feet drops with tons of roots (no snickering from the freeriders, I know it sounds small to you all), I've been watching my travel. I'm getting about 3 inches. This is about the hardest I'm ever going to slam the front end down, so I'd like to soften it up a bit and use at least another half inch of travel, maybe 3/4". I'm afraid that if I let out enough air to get it to use that much travel, it'll feel saggy when I'm on the smoother sections of trail. Right now, I'm running about 85 PSI with one click of rebound slower than the center click. I'm about 175-180 lbs. That nets me about 5/8" of sag.
So, my question is how much does an inch of travel make in the head tube angle and would I feel a difference in geometry if my fork was compressed further on normal riding and when taking drops? The head angle is listed at 71 degrees. I just want to make sure my head angle doesn't get too steep when the fork fully compresses. I already have enough endos to last me a while. Thanks.
P.S. down the road, I may send the fork to PUSH and have it PUSHED and converted to the RLC model. Would the addition of compression adjustment help my situation?
