Matthew_Gibson Posted July 21, 2005 Report Share Posted July 21, 2005 (edited) The other day I was riding and I was trying an 8 foot gap to a wall, I wasn't landing than hard on the back wheel (ehco rim). Well anyhow I checked my rim and it was rubbing on the rim and I couldn't turn the rim, even when I tried to pedal! Today (after my dad built and trued the wheel up) it done the same, but on a lot smaller gap (6footish). Do you think I should get a new rim or get it built up my someone in the know?? Please help Thanks Matt :S Edited July 21, 2005 by Matt Gibson Quote Link to comment Share on other sites More sharing options...
CurtisRider Posted July 21, 2005 Report Share Posted July 21, 2005 your rim was rubbing on the rim? im guessing you mean brake.... get tart to build you wheel, its quite likely that your dad isnt quite as experienced as him.... Quote Link to comment Share on other sites More sharing options...

Yeah very ← God knows then, i very much doubt you need a new rim though :S :S :S just send it off to tarty and get it sorted :S (dont spend money on a new rim... save for a new frame! :D ) Quote Link to comment Share on other sites More sharing options...
Nick Garland Posted July 21, 2005 Report Share Posted July 21, 2005 Guna get a new rim because i think iv got a flat spot in the rim!!!! Yeah very ← As far as Im aware flat spots dont make it go to the side, someone correct me if im wrong, I've flat spotted two rims and never had it rub on the pad :S Send it to Adam he will sort it most likely, if not then he can build it up with a new rim.

James_Porter Posted July 21, 2005 Report Share Posted July 21, 2005 you can flat spot it so much that it makes the tyre rub on the pad... or is it the actual rim that is rubbing on the padeo? Quote Link to comment Share on other sites More sharing options...
N.Wood Posted July 21, 2005 Report Share Posted July 21, 2005 If it's a new-style Echo rim, then that's your problem. Quote Link to comment Share on other sites More sharing options...
dave33 Posted July 21, 2005 Report Share Posted July 21, 2005 the rims flexing side to side when ur pedaling hard :S tension the spokes correctly :D Quote Link to comment Share on other sites More sharing options...
philking Posted July 21, 2005 Report Share Posted July 21, 2005 the rims flexing side to side when ur pedaling hard :S tension the spokes correctly :D ← That'll be the problem, was the case when i had a cheap build, but now i have a tarty build it is fine... correct spoke tension is needed.

The rim rubs on the rim and u can see it move closer! and i found the flat stop when I was rebuilding it! If it's a new-style Echo rim, then that's your problem.\ Whats wrong wid em???

JIX Posted July 22, 2005 Report Share Posted July 22, 2005 I would say tighten the spokes properly, and also if you have a hub with cones then make sure they are tight. Also make sure your qr is ok, because some times I used to bash them about and bend the lever area so that when you tried to do it up it was very stiff to move even though the qr wasnt actually tightening the wheel to the frame. If that makes sense :- Quote Link to comment Share on other sites More sharing options...

Please help Thanks Matt :- ← Sounds like a proper wheelbuild is needed possibly or a good true up If t is just a flat spot use a shifting spanner and a hammer to bring it out be very careful not to pull out flat spot too much a light file or sand will help to if not already ground to ensure an even braking suface hope this helps good luck Quote Link to comment Share on other sites More sharing options...
andyroo Posted July 22, 2005 Report Share Posted July 22, 2005 I don't know your personal setup, but are you running a Hope QR skewer on the derriere? ← Thats what i was thinking... my mate has a very well built wheel, but even if he stands on the qr to make super, or even uber tight, a smallish gap will move his wheel. Get a shimano qr instead, see if that works before you shell out on a new pair of shoes Quote Link to comment Share on other sites More sharing options...

Thanks Matt :- :D ← In that you're again saying the rim rubs on the rim it's kinda hard to know what the crap you're talking about, but if it's moving side to side that ISN'T a "flat spot", that's just a buckled wheel. A flat spot is where the upright sidewalls of your rim have been crushed/bent flat, making a 'dent' in the side of the rim. Typically, they go inwards towards the centre of the rim, as opposed to out, so it shouldn't *Really* rub on the pads at all. It just sounds like you've got a buckled wheel? Either way though - Hope QR skewer or not? Quote Link to comment Share on other sites More sharing options...
jamesb Posted July 22, 2005 Report Share Posted July 22, 2005 Get it tensioned properly and every week afterwards check to see if it gets loose. Spokes on trials bikes need to b very tight. Quote Link to comment Share on other sites More sharing options...
JIX Posted July 22, 2005 Report Share Posted July 22, 2005 On a slightly seperate note, I have just got a rear classic king and the spokes in the wheel are quite loose. I want to tension them but Im not sure how tight to go as I have heard you shouldnt tension a king wheel to much because they can pull the shell apart slighlty and make it skip, and also that if its too tight it can rip the flanges off. Mr porter says he has his quite tight and has had no problem, what is the view of people who have kings and who know how to build??? Quote Link to comment Share on other sites More sharing options...

The whell moves side to side-Buckled wheel And there a flat spot in the rim- Flat spot I no what a flat spot is , I had a sunn rim it was like cheese!! But thanks anyhow lads! :- Im not bother getting a new rim I'll send it off to tarty when if got some money! Quote Link to comment Share on other sites More sharing options...
