Warped rim?

If the pads are old or unused for a bit, or glazed they can get grabby. I don't know if new rims can compound that problem. Just a thought.

Check for residue on the rim, clean it with alcohol and give the pads a quick sand with some light sand paper.

Failing that, buy swiss stop pads.

According to the internet ,ultra low spoke count plus Shimano's v.high spoke tension s on the ultralight rim can make the braking surface a bit 'wavy' on C24s.

I had the wheel checked over by wheelbuilding guru Paolo Coppo (http://paolocoppo.drupalgardens.com/). He found that the spokes were evenly tensioned and the wheel was true, but he when checked with a micrometer, there was a lot of side-to-side movement of the rim between each spoke. He concluded that the rim isn't rigid enough to be supported by such a small number of spokes.

dubtap; droppin' knowledge

I had a set but never noticed this myself.

Thanks for all the info/advice. In the first instance i'll give them a good clean and properly check the pads. If the problem persists where do I stand? Is it a design issue?

Is braking really necessary?

Not on freewheel bikes, but on fixed bikes you mustn’t stop braking while the wheels are turning or you might go over the handling bars.

Whats a fixed biek?

Has anyone got a deal on Shimano r501 at the minute?

My rear inner tube just exploded earlier this morning, luckily next door in the office while we had a meeting. HED Ardennes Plus. I assume installation error when I changed the tube when I had my first puncture on these three weeks ago? How did it pinch when I had pumped the tube before putting the tyre back on? Any ideas appreciated. This is scary.

Check the rim tape

That has happened to me because I had Velox rim tape and there was some water inside the tyre that had corroded it.

As above... but sometimes pinched butyl just goes.

Thank you. Where is hippy?

Did I ride into something or is this production error?

^

i had a sidewall blowout with that tyre a few months ago, Mind you the split was circumferential. I blamed installation error, I went at it with tyre levers pretty hard.

Anyways, took it back to lbs and they gave me another and sent the old back to reclaim their dosh from conti

On the road? Maybe they are too badly produced for me now. This is not through a cut from road debris then?

It was your riding style.

Your one looks like a cut from the road to me. Mine blew out whilst rolling away from some lights at very slow mph so not catastrophic thankfully. Like I said, I think mine was because I was a muppet with my tyre levers. I've used those levers for poking and scraping against things in the past so their tips are quite sharp now. I was an idiot to use them.

Gone through about 15 gp4000s tyres and never had a failure so I wouldn't jump to the conclusion that they are badly produced.

A cut from the middle of the tread out to the sidewall?

Looks like the kind of thing you'd get from leaning

^haha
