Hi Mel!
Since graduating from hardtail to a full suspension Giant Trance 2 a couple years ago, I can't seem to find the right balance between tire and rear shock pressure. Our group does mostly XC riding on a fairly technical single track with lotsa stumps, rocks, roots and a couple short but nasty loose rocky climbs. On my hardtail I found that 2/3 "normal" tire pressure worked great. With my new bike I'm finding I either need more tire pressure or I need to boost the shock pressure about 20psi higher than what is spec'ed for my weight. Otherwise I have ratchet way too often to keep myself from burying my cranks in the dirt. The problem is I just can't seem to find the right pressure balance. Any suggestions? Thanks!
