Smo™ Posted September 10, 2005 Report Share Posted September 10, 2005 Hey guys, recently I bought a KOT MS2 and it rides perfectly, I love it to bits. But the frame is such an asshole, every time I push down on the pedals, the frame flexes so much that the wheel is pulled over into the brake pad and I get unbearable rub which f**ks me up. I lose speed in run ups for taps, I can't gap for shit because every time I kick the f**kin brake is on. Now is this just my frame that's the problem? Has it happened to others? Is my wheel f**ked? I've tried truing the wheel, hundreds of times, redishing it etc. but nothing is working. It still rubs like an asshole. It's pissing me off so much I just don't want to ride it anymore. What can I do? Quote Link to comment Share on other sites More sharing options...
Dr. Nick Riviera Posted September 10, 2005 Report Share Posted September 10, 2005 bitch slap the guy who designed it? or try a narrower rim ( 521 ) or something Quote Link to comment Share on other sites More sharing options...
Tomm Posted September 10, 2005 Report Share Posted September 10, 2005 I have no experience of the frame, but I would be VERY surprised if it flexed as much as you are describing. I would be much more inclined to think it was some kind of brake setup or wheel problem. Quote Link to comment Share on other sites More sharing options...
Janson Posted September 10, 2005 Report Share Posted September 10, 2005 Are the spokes as tight as they can be? I had problems with rubbing brake when pedalling on my crescent, but after tightening the spokes tightly, it didn't rub. your QR skewer might be loose or flexes a bit? If it is the wheel, you could get the spokes soldered, to add stiffness. You wrap some soldering wire tightly around where the spokes cross.. I have done the same thing but with zip-ties. am not too sure it works, but I think it does. Quote Link to comment Share on other sites More sharing options...
Smo™ Posted September 10, 2005 Author Report Share Posted September 10, 2005 (edited) Well I was just outside, held my front brake on and pushed down on the drive side pedal and I can see the wheel pulling over. It looks so much like the frame is flexing, but I've no idea how I can know for sure. Edit: Janson, if I tighten up all my spokes, won't it mess up the true or dish? I presume you mean for me to tighten every spoke? Edited September 10, 2005 by Smo Quote Link to comment Share on other sites More sharing options...

What can I do? ← Nah man your not the only one. It happened to Damon Watson, and it still sometimes does. He just trued and tensioned his spokes loads, so it doesnt do it as much. Also he has his brake set-up so the lever doesnt come in far at all. I suggest you put loadsa tension in your wheel, and maybe put some more fluid in your brake? so the pads can be set further away.

I reckon I may have to try more tension in the wheel as everyone suggst, but I'm a little confused with how to go about it. Quote Link to comment Share on other sites More sharing options...
Janson Posted September 10, 2005 Report Share Posted September 10, 2005 yeah, tighten every spoke. lots. so that they are über tight. i guess you could dish the wheel so that the distance between the pads and rim is uneven, with the biggest gap on the side which the rim flexes over to.

To do that I'd need to loosen some on one side, meaning that they're not all really tight anymore? Argh, confusing >_< Quote Link to comment Share on other sites More sharing options...
Janson Posted September 10, 2005 Report Share Posted September 10, 2005 1. make sure all spokes are similarly tensioned 2. dish the wheel, by tightening the spokes on one side, and loosening the other side. 3. this should leave the wheel dished, but with similar tension in the spokes, as you just moved the rim over. 4. tighten the spokes normally, making sure the rim is true and all spokes are of even tension. keep going at it until they feel stiff. 5. for my tuning, i use zip-ties in the spoke crosses, which feels like it adds some stiffness to the wheel. also, if you snap a spoke, it is held in place by the zip-tie, so it won't fall out in the wheel or get tangled somewhere.

Luke Drewery Posted September 10, 2005 Report Share Posted September 10, 2005 It cant be the frame unless its faulty as look at matt staples and damon watson, those guys go huge and i assume their brakes dont rub every time they put pressure throug the pedals. I had the same problem on my koxx and my t-rex that i have now. Half an hour of fiddling with spoke tension sorted the problem for me, been good ever since. :- Quote Link to comment Share on other sites More sharing options...

Mr Motivator Posted September 10, 2005 Report Share Posted September 10, 2005 Tension your spokes? Just go round and tighten each one a quarter turn and see if that rectifys it? Should have kept the pitbull, BB rise sucks :- Quote Link to comment Share on other sites More sharing options...
Tim Stedman Posted September 11, 2005 Report Share Posted September 11, 2005 Have you checked your hub axle, because if thats broken, it can cause similar problems to what you're describing. Quote Link to comment Share on other sites More sharing options...

I lose speed in run ups for taps, I can't gap for shit because every time I kick the f**kin brake is on. ← BTW, if you tighten every spoke it's not going to stop the chain pulling the wheel across is it? It might prevent the brake from dragging when you lean the bike over, but if anything it'll make your pedalling problem worse because you'll be stiffening the rear wheel. That's fancy frame designs for you... Quote Link to comment Share on other sites More sharing options...
Damon W Posted September 12, 2005 Report Share Posted September 12, 2005 when mine does it its my wheel, i broke my old wheel and i used Dave@tartybikes and THAT is when it does it.the spokes have lost all tension, with my wheel its fine, at first it did it but it was because my brake needed refilling and my spokes were lose. <_< make those ammendments and youre onto a winner :ermm: :unsure: Quote Link to comment Share on other sites More sharing options...
