Straight and true, I wish they were (Rims)

Hey Guys,

Basically a bit of background; I ride a trek fuel ex8 2007 (spec: http://www.trekbikes.com/uk/en/bikes/20 ... ve/fuelex8). I recently got a service which cost me an arm and a leg. At the time they mentioned that my wheels wern't 100% true both being slightly warped (reluctant to spend more many I left them for the time being). I'd never noticed this before but have always had trouble with my disc brakes moving out of alignment and rubbing I now realise this was probably the cause.. do you think?

Being a poor student :cry: I am reluctant to buy new rims get them fitted etc so do you think a bike shop will be able to true them? If i do need new rims and possibly spokes etc what would you guys recommend, i've heard good things about mavic 717's but would they be strong enough? My riding style is mainly heavy XC with some AM elements with the occasional trip to Afan and Scotland...

Any advice welcome

Thanks

Dan :)

    Maybe not, i'm not the most mechanically minded. Just crossed my mind that the problems could be linked. :oops: sorry

    well they could be but only if the hub was the cause. through worn bearings or some other damage.

    have a thing if you cut your spokes and removed the rim and the tyre the disc would still do what it did before.

    Yeh, thinking about it I see what you mean. Any thoughts on how likely they able to be trued(?) and what rims you would recommend? Ta

    Why not just have them trued?

    Far cheaper than a new set of 717 wheels, and if your rotors are warped, they can be straightened as well. If they're horribly worn and dangerous, new rotors aren't so expensive.

    That way you're comfy, safe, and have money left for school or beer.

    I like mapei's thinking :lol: just thought they might be beyond repair... Shall take them in next week and see what they say.

    if the rim is untrue, then there is a force being applied horintally as the rim moves, this could then cause a bending moment such that it could bend the hub and then the disc, which as the disc and pads only have a small seperation, which could explain the rubbing. but im not completly sure about this.

    i too have a similar problem and think this is why my disc are rubbing. if this is right then a good truing should sort the problem.

    hope i helped

    if you haven't noticed it before then it probably isn't that bad (just by looking down at the wheels when riding and you'll notice how true they are) so your best going for the true imho, and get something else with the money you save like sorting your brakes out and beer!
    if it ain't rainin.....it ain't trainin
    Stick your 'rules' up your a%se
