Pressures (tyres and forks) for Giant XTC 2.0 29er ?

weeksy59

Hi guys...

God my new Giant is just WAyyyyyyyyyy too stiff.

Can i get an idea of what pressures should be in my forks and tyres as a guesstimate please ?

new 2011 Giant XTC 29er, running,
Fox F29 RL-11, tapered steerer, QR15, 100mm travel

Rider 88kg kitted out.

I'll have a play with rebound etc later too.

On the ride with jumps/drops i seem to have used 65-70% of viewed available travel.

Surely you've been around the forum long enough to know the answers to your questions?

1) forks: set sag at ~30%

2) ride and adjust as needed

3) tyre pressure: enough to not get pinch flats but not too much to lose grip

4) ride and adjust as needed

Yes but my questions were more 29er orinetated as opposed to generic MTB.

I was wondering if 29ers had an optimum style due to different characteristics.

26", 29"... all the same as for setting stuff up

Looking at the Giant... Hmmm yes... I should have checked more earlier and before the race.

Forks are set to approx 12% rider sag... and my rear pressure was in the high 40's.

Hence why the beast was a little on the stiff side.

I say 'are' i mean 'were'... they're now 33psi on the front and rear and 35% sag.
