1. The most important thing about buying a new bike is to make sure it fits. The only way you'll know if the bike is right for you is to size up the bike and make sure that the bike's geometry matches your body's geometry. Ask questions and do some research.

2. If possible, try to find a shop that will let you demo the bike on real dirt. Five minutes in a parking lot won't cut it. You wouldn't buy a car without a real world test drive, and a bike should be no different.
3. Don't belive the hype. Just because your favorite rider or best friend rides a certain bike, that doesn't mean that's the best one for you. Have an open mind and be realistic about your needs and ability.

    UPDate : Suntour XCM stuck preload knob - partially unstuck

    I have a Suntour XCM V3 HLO 100mm travel fork on my 2011 trek 4500.

    The preload knob was stuck and when I tried loosening it with pliers, it got slightly warped. Fortunately, it was cosmetic. It moved only 2-3 mm.

    I tried again with an adjustable wrench and now, its moving more freely.
    It also looks like it's working (as I need to press harder on fork to make it move with extra preload. I have not tried sitting on bike).

    1)My doubt now is how many turns can I twist it either way ( - or + ).

    2) I have Finish line wet lube and also finishline stanchion lube.

    Should I put either of the above lubes around the preload adjuster to loosen it further?

    3) Do I need to do any maintenance for preload system ?

    My lockout knob is ok ( Possibly because I use it often).

    Thanks in advance and thanks to all who responded to my previous queries.

    Have a nice one.

    I would advise removing the topcap and getting inside the fork rather than try and force things. You need a special tool though I think although could be a work around. In anycase I'm interested since I have a new XCT. Haven't even messed with preload now.

    Mine did the same thing. My new Manitou Tower should be here this week at which point I plan on going "office space" on my suntour

    Hi, I turned it towards less preload. I may have moved it towards minimum setting. It seems to be stuck again. The travel is 100mm. I tied a ziptie and when I sat on cycle and pressed brake too, displacement (sag) is approximately 32mm. Looks like this setting is ok. I weigh approx 215 pounds.
