Andrex Posted November 20, 2006 Report Share Posted November 20, 2006 I've had to replace a broken spring in my hope xc hub and since I've put it back together my wheel keeps rubbing on the brake when I pedal. I've trued the wheel, put it dead straight in the drop out, checked to see if my axle in the hub has snapped, but the wheel will still rub on the brake, but it is only when I pedal. Has anyone got any clue to what is wrong with it? Quote Link to comment Share on other sites More sharing options...
Tom Perkins Posted November 20, 2006 Report Share Posted November 20, 2006 Your brake pad might be worn at an angle. Re-postition the brakes. Quote Link to comment Share on other sites More sharing options...

Dan6061 Posted November 20, 2006 Report Share Posted November 20, 2006 Are the spokes tight?The wheel could be 'flexing' over as you pedal. Especially if it's the drive-side pad that rubs...I know you said you trued it, but are all the spokes actually tight? Quote Link to comment Share on other sites More sharing options...
Alun Goch Posted November 20, 2006 Report Share Posted November 20, 2006 Does the wheel move from side to side if you try to move it? Could just be the bearings loose...Alun Quote Link to comment Share on other sites More sharing options...

Could it be something to do with my hub? Quote Link to comment Share on other sites More sharing options...

Chain or seat stays snappage would give rear flex.Hope it,s not but best have a look buddy Quote Link to comment Share on other sites More sharing options...
David Biddle™ Posted November 20, 2006 Report Share Posted November 20, 2006 check the flange on the hub see if there is no cracks or eneything like that or it may be time to get a new rim my ronnie done that after a few big drops so i changed rims and its bin fine Quote Link to comment Share on other sites More sharing options...
MikeCottTrials Posted November 20, 2006 Report Share Posted November 20, 2006 tighten all your spokes Quote Link to comment Share on other sites More sharing options...
SemteX Posted November 20, 2006 Report Share Posted November 20, 2006 When you pull the brake does the wheel push to one side? I could also move the wheel from side to side with my hand. This happened to me with my pro2. Bearings had died. Check em. Quote Link to comment Share on other sites More sharing options...
darrenhopper Posted November 21, 2006 Report Share Posted November 21, 2006 Sounds alot like a dying frame. My last bike diedthat way. It was snapped behind the BB on the drive side & everyt time I'd put in a pedal stroke it would flex 'till the tire hit the frame.Give it a good clean & a look over. Hope it's not broken though.

Rupertbear Posted November 21, 2006 Report Share Posted November 21, 2006 sounds as if there is not enough tension on the spokes and the rims flexing on the drive side as you pedal, hope this helpsrupert Quote Link to comment Share on other sites More sharing options...
PEACHY Posted November 21, 2006 Report Share Posted November 21, 2006 check your bearings my wheel did that and the bearings were dead as the dodo .but the frame point was gud jus keep checkin it and lookin for the problem.gud look i hope ye bike aint broke Quote Link to comment Share on other sites More sharing options...
Krisboats Posted November 21, 2006 Report Share Posted November 21, 2006 Ha ha, so many different replies. Right, he said he's checked the spokes and their all tight and the wheel is trued... so no more posts saying tighten your spokes.Have you checked the rear axle, it may be partially snapped. With a skewer in it would hold but it might move when force is exerted on it. Take the wheel out and get that axle out to have a look at it.While the axle is out have a look at the bearings, as people have said it could be them that have died.Check the frame thoroughly for cracks, mainly around the bottom bracket and chainstay/seatstay joins.

kyle-livesey Posted November 21, 2006 Report Share Posted November 21, 2006 all wheels have a certain amout of flex som more than others so mods wont flex as much as stock because they are smarller Quote Link to comment Share on other sites More sharing options...
Krisboats Posted November 21, 2006 Report Share Posted November 21, 2006 all wheels have a certain amout of flex som more than others so mods wont flex as much as stock because they are smarller I think what dan means is your wheels aren't supposed to flex when pedalling like that, and that hardly anyones does... if they do, they get it fixed. And surely you are aware that your advice of "move your brake pads away from the wheel and put some tpa on" is completely contradictory in the fact that the TPA moves the pads closer to the rim, effectively making the need to move them away in the first place completely uneccessary. Pads should be 1-3mm away from the rim depending on how you like them set up, magura advise 2mm but personally i like 3. THEN you use the TPA to adjust the feel of your lever and for taking pad wear into consideration. Quote Link to comment Share on other sites More sharing options...

No, what Dan means is that his wheel doesn't flex about when I pull the brake..Not that i've noticed anyway...Wasn't very clear in the other post..

gundam Posted November 21, 2006 Report Share Posted November 21, 2006 1. Check the frame very carefully for cracks2. Check spokes are corretly tensioned (should be able to move them about 1cm when squeezed on a 26)3. Pick you backwheel up and wobble it from side to side to see if youve got any bearing wear.4. Check hub and rim for cracks5.Check your qr is tight, may sound silly but could help alot6. Might just be general wheel flex Quote Link to comment Share on other sites More sharing options...
Andrex Posted November 21, 2006 Author Report Share Posted November 21, 2006 I think I've sorted it out now because what I done was undo the whole wheel so the spokes loose then redone it all back up and tensioned it a bit more on the drive side than the non-drive side. I checked to see if the axle or frame was cracked but they were fine. Cheers for all your help Quote Link to comment Share on other sites More sharing options...
chasthetrialsrider Posted November 22, 2006 Report Share Posted November 22, 2006 ok I have had this problem a load of times and to solve it i just tightened up my axle bolt on the drive side of the wheel do it until you cant tighten it any more Quote Link to comment Share on other sites More sharing options...
