    ive got a haro v1 bike
    just changed the lousy stock fork to a 2004 marzocchi exr pro
    loved it , rebound is fast.

    alright lets get to the point,
    i just got my bike wheel trued from some bike shop far away, 1 hrs ride away from home. well it was trued , i saw it. but after the ride home
    both wheels got untrued again
    is it the wheels or my riding style?

    i went up lots of 10cm high curbs and down 20 cm curbs
    hit a few branches thats all.

    using the stock wheel from the above mentioned bike.
    i was wondering if its the wheel or me?
    😕

    any body please enlighten me
    thank you

    Given that this is an entry level ride, I would be inclined to assume that the wheels were machine built without spoke prep compound. I would furthermore be inclined to assume that the mechanic was not relieving the torsional stress on the nipples during and after the truing process. Riding the bike home took care of this. Unfortunately, that meant the spokes pulled the wheels right back out of true.

    A good wheelsmith is worth every penny. Either find one and stay loyal to him or her or learn how to properly true wheels yourself. It isn't all that hard to do and being a bit anal about the process really pays off.

    I'd say it's the wheels. Good setup with poor parts can usually stay true a long time unless overstressed. Poor setup with good parts can fail right outside the shop...

    It could be both you and the wheels.
    You may have damaged the rims before and/or after the truing.
    1. Where the spokes properly and evenly tensioned before you brought them in for truing?
    2. Where the spokes evely tensioned after the truing?
    3. Where the spokes stress relieved?
    4. Was the residual spoke windup removed? (did you hear any pinging as you rode?)
    5. Are the rims wider at areas as you go around? (if you don't have truing stand or calipers you can use an adjustable wrench when you remove the tires. If they are, the rims are damaged.)

    Also, your weight, tire inflation, actual contact contour and force will all make a difference if the rim(s) suffer plastic deformation.
