    Noob front suspension and tire pressure questions

    Hi all, I'm really glad I found this forum... I'm learning ALOT!

    well my question here has to do with my front fork for my new Gary Fisher Wahoo. Here's the specs if you need them:

    Main frame Gold Series 6061 T6 internally and externally butted aluminum | Genesis Geometry

    Fork RockShox J1 | 100mm travel | Preload adjust

    Headset Aheadset | Semi-cartridge | Sealed

    Bottom bracket Cartridge

    Crank Shimano MC09 42/32/22

    Pedals Nylon platform

    Front derailleur Shimano Acera

    Rear derailleur Shimano Alivio

    Shifters Shimano EF50

    Cassette SRAM PG830 | 11-32 | 8spd

    Chain Shimano IG51

    Front hub Alloy
    Front rim Bontrager Camino
    Front spokes 14G Stainless Steel

    Rear hub Shimano RM60-8
    Rear rim Bontrager Camino
    Rear spokes 14G Stainless Steel

    Front Tire Bontrager Jones XR 26x2.25

    Rear tire Bontrager Jones XR 26x2.2

    Front brake Tektro 845AL V

    Rear brake Tektro 845AL V

    Brake levers Shimano EF50

    Handlebar Bontrager Crowbar Sport

    Stem Bontrager Sport | 25d rise

    Grips Bontrager Dual Density

    Saddle Bontrager Select ATB

    Seatpost Bontrager Sport

    -----------------------------------------

    My front suspension seems to have gotten softer since I first bought the bike (might just be my imagination), and since I've been only riding around town, I was hoping the "preload" adjust could help me make the front stiffer. I've heard that the harder your front suspension is, the easier it is to go up hills and such. I've experimented with turning it clockwise (it says "+" for clockwise, "-" for counterclockwise) but I didn't notice any difference. Can you enlighten me on this?

    My next question is about tire pressure... what PSI should these tires be at?

    THanks, sorry for all the newbie questions

    Yep, most forks should loosen up over the first 3hours of riding usually. Infact it might seem like a bit of a surpise when it does! I'm not too farmilier with the J1, but i think thats the lowest RockShox fork...so i wouldn't excpet wonders from the adjustment unfortuently.

    RE: Tyre pressure - It will depend on how much you weigh and what conditions you are riding in. I run 50PSI on road in general, but when doing XC i'll run about 40PSI...and if the conditions are really bad i'll just drop it down a bit more. Tyre pressure is a personal preference though, you will need to experiment. I suggest starting it off at a certain pressure and seeing how you feel, then adding a bit more and testing that pressure etc. Remember, you will use different pressures for different conditions (e.g. the higher the pressure, generally the faster the tyre will roll but the less grip it will provide).

    Hope this helps.

    Personal preference plays a large role in determining tire pressure. Just remember lower pressures can lend to pinch flats. I typically ride at 40-45psi.

    Tire Pressure: What does the tire mfg. recommend?...this is always on the sidewall...its important to keep it between the min/max, whatever suits you best

    Fork: adjusting the preload will only adjust the sag...what you need is a fork with rebound adjustment to be able to adjust the "cushion", and yes, a stiff fork helps on climbs and when racing, but you would need a fork with a lockout or a serious rebound control (but then you would have to keep resetting it on the decents)

    I regularly run my tires below the recommended minimum.

    My rst fork on my 4300 had that +/- dealy, and I never felt a difference either.
