Rim dent and lip straightening

Post by Huffnpuffer »

Ive got a front rim that has a slight dent in the inside of the rim and the lip of the rim is bent out by about 5mm x 40mm long. There is another one approx 45 degrees on the opposite side of the rim. My front fender has a big stress mark at 45 degrees to the side of the fender. Left side plastics are scratched up a bit. Just guessing the 3 happend at the same time. Low front tyre pressure, riders hit a curb or tree, crossed up the hangers and dropped the bike causing all the damage. History pickin aside i want to fix the rim buckles and dents. Has anyone got any ideas on how to repair them or done it? Not much info i can find on it. I am currently making a a tool to stretch between the hub and rim to get the inside dent out. I will preheat and clench in the process.
I know its not recommend before I get told but the rims arnt the worst justwant tbe oem origionals.

I've seen bends fixed. No heat was used.
Thewheelmaster.com can fix you up, but he's not cheap.

It can be done. Cracks are the most common result unless done with care. I have repaired small rim dings using a wrench and a little heat. A press would work, you could cobble up a homemade die to match the rim contour.

I have never tried it myself, but I have read a of a couple of people recommending wooden blocks to help it keep shape.

Different ways to do it I guess. I've fixed dozens of bent rims with a press, no heat. Allow for a little spring-back.
