dent in rear brake track...

Hit a pothole quite hard today with my rear rim. Tire came unseated and tube went flat.

Can I bend a small dent out of the rear brake track with an adjustable wrench?

It's about one-third of a finger tip large!

Pics? For bending out may work, may not, have done some successfully, some not. would be useful to know the type of rim, if you run tubes or tubeless, rim or disc brake etc

You my be able to fix that, but be careful to not make it worse. For best results try to use a wood mallet on a solid fat & sturdy wood surface & tap it back into shape gently. I'd need a photo to give better advice.

By the way, how fast were you going?

Fixed.

I brought it to the shop during lunch. Adjustable spanner and bent it back. They bike guys were shocked at how malleable the rim lips were. I have a tiny warp that you can hear when the rear brake is fully depressed, but such is life!

Cost £12.95 for another tube, replacement and bending.

23-622 tire/tube holds 110psi fine!

On with the commuting!

edit: Speed was somewhere between 30 and 35kmh (20 or so mph). damn British roads.

Good to hear its fixed & glad you're OK!!!

ALU is very malleable, so not surprised. Just be careful, because bending it with a tool can fatigue that area & deform the profile!!

My inner armchair detective wonders how the front wheel escaped injury in this scenario...

You Managed to go around the potholes pretty good up until then, but, Spring time is also when new potholes also Bloom ..

Bring spray paint and highlight them .. probably need the cans that work upside down..

Well since the rear wheel doesn't steer, it follows the front wheel on a different radius. Most of a rider's weight is on the rear wheel as well, making it more prone to this kinda stuff. I've missed things with front wheel only to run right over with rear wheel, inclding a 3-4 inch chunk of concrete from a matching hole in the road nearby, nearly crashed, foot slipped & toe dragged on ground jamming the pedal into my ankle nice and hard. Isn't physics fun?!?!

I actually cut the corner too short with the rear wheel.

Dumb! Dumb! Dumb!

At least rolls relatively well again!

28 (or 32?) mm tyres should help with that. If they can be mounted.

Grass? Try to avoid that stuff while you are riding...it'll definitely impair your judgment. And it will make you lazy.

I can't avoid it it was a warm and wet winter, and the first bloom just happened. The first grass cuts at the uni just happened and there's pile of grass everywhere.

I'll try to avoid it next time as I don't know how many dings the wheel can handle
