How To Repair A Dented Bike Rim

- I had a bicycle rim with a dent. The sides were bent out. Probably from a previous owner hitting a rock or a curb or something. So I decided to fix it and make video of how to do it.

Had to do this job a while back and adapted/improved the bench vice method by using a sized wood offcut to brace internally between the rims.
This allowed me to tighten the vice hard and get a flatter finish but without the risk of cruching the brake surface inwards.
I found the adjustable spanner technique to give a less consistent, more wavy finish that was a noticeable fluctuation when braking.
Dude, you saved my rim! Thank you!!!!
Awesome!
RJ the king of the vintage bikes.
Kyriakos Michael, yes, you can bend the rim out too, Use the wrench to gently bend the rim back out. Take your time and work in small increments.
Thanks for the video it was very helpful
Awesome! I have a vintage BMX wheel that came down hard on a curb and has a outward dent in it....I was going to use a vice but was worried that pulling the dent in might push the straight areas on the sides of the dent inward some. Do you ever have to use some kind of blocking on the inside of the rim to keep the areas around the dent straight? If so, what do you use?
cut a piece of wood (preferably harder than pine, assuming it's a steel rim) to fit inside of the rim. that's especially important if it's a very sharp outward dent, the one in the video is fairly smooth
As usual, RJ has the exact solution to my problem. Thanks again.
This is all i needed thank you so much!❤
thank you for sharing. you saved my wallet and made my son very happy
Another highly informative and much needed video, thanks a million 👍
Appreciate the video! Saved me some $$ thank you
RJ’s the man! Thanks for putting this up.
Thanks, RJ! Always find your videos so helpful, informative and easy to follow. Well done!
Thanks RJ, great help as always.
Will this work with tubeless tires and an inward dent?
Thanks!!! Works awesomely!! Fixed!
You will probably have to true the wheel after fixing the dent. But the braking surface should be pretty good. Munch better than with the dent.
I don't see how you could possible ride this. I dented my rim and from the start it was MUCH less of a dent/bulge than this. Putting a standard razor blade on the rim showed it was less than a quarter of a millimeter from perfectly straight. Yet I could still feel it like crazy when braking. Every time that part of the rim past the brakes it was a very noticeable thump.
The only way that I have found is to use a file though some brake surface is removed.
Thank you❤
Excellent video!
Very helpful. Thank you.
Thank you that helped very much
How did it get bent out?! I've only dented my rims to the direction of the tire bead
Thank you so much for this!!
i have a small outward dent that is wrecking my nerves... will try this
What about heating the alloy before bending?
Nice video, it help me a bit ... I have a Question, what about when is not an outside but inside instead? Who can I pull it out straight again?
Carefully bend it out.
thanks buddy
You really are amazing, as an 18 ur old girl with not a lot of money, you’ve saved me a ton THANK YOU
Hi RJ, thanks for the video. How come you didn't use any heat? Would using a torch to heat it up make it a bit easier?
Not with aluminum rims
Hi Rj any tips of getting inwards dents out
Is that a aluminum rim?
Will this affect wheel tru and braking surface?
ad before video was pepsi with lime,rj loves his pepsi :)
Really? You got a Pepsi ad? I got one for diabetes. LOL!
+RJ The Bike Guy yup pepsi au, it said,oh the irony!!!!!!,is ut trying to tell us something?? :D
My rim is 26x4 and I dropped it while trying to replace tube fell a couple feet and it's ridding up and down its not bent to the side it's just pushed inward towards the hub
The wheel will probably have to be rebuilt. Maybe a new rim.
my wheelset bent on a 1/4 of the wheel ( WIDE BENT ) what's your suggestion?
please , give me your help bro
So I have a small inward dent on a rim that was a result of unfortunate hit by a heavy object. It can't be bent back by a wrench because it's so small, but it interferes with the break pads. It also doesn't really change the rim's geometry much since it's kinda in the middle of the surface.
I was wondering if sanding that surface and then filling it with epoxy might be a good way to restore surface smoothness? Just not sure how well it will bind to aluminium and whether it will let the brake pad slide across or increase friction
Probably not. You can always replace the rim.
Hey man,i was wondering if that would work from the inside out.(bents the opposite way from the rim in the video)help.
Try the wrench method
What about if the rim is dented in such a way that the rim is physically smaller radius to the axle? Any tips there? Hammer?
It may or may not be able to be fixed. Might be easier to replace the rim or wheel.
what if the dent go inwards or whatsitcalled what can you do then?=
Hey my bike Rim is bent inwards on a aluminum rim could you help me with that ?
You can try to straighten it. Aluminum doesn't like being bent, but it's worth a shot. Be patient and don't overdo it to where you are bending it back and forth.
RJ The Bike Guy Thanks !
RJ The Bike Guy but would it be ruined completely? Would you replace the rim ?
@@Eng586 If the choice is replacing, or trying to fix it, and maybe damaging it, and replacing it anyway, you might as well try to fix it.
My alloy rim got little dent on the inside is it repairable?
Maybe.
Ok so I got a fat bike and while painting the rims the rim fell and make the rim kinda be block like on one side
what do you do if the dent bends the lip of the rim inward? how can you fix that?
Bend it out. Probably with the adjustable wrench.
Thanks
Shyflirt,i would realy advise against doing this. those 700 wheels are aluminium and it always is weakened when bent back into place, next thing you know you go trough a pothole and get a giant crack in the rim. you really should never bend aluminium back to its original position it stresses the metal too much
excalebuir You are being paranoid. Most dents that anyone would attempt to fix themselves would be small enough that it is not going to cause fatigue even on an aluminum rim. IT is not as if you are bending it back and forth several times. Bending it a millimeter back is not going to compromise the integrity of the aluminum.
Had this same problem but I destroyed the rim trying to fix the dam thing cuz I got pissed at it
I have this nagging problem with my front wheel that I just can't identify. My front brakes have been pulsing for several months. And at first I thought my rim was toast, so I got a new wheel. But it still does it.
I checked my brake caliper, checked and changed my brake pads, I centered my caliper so they engage evenly and agonizing trued the wheel over several sessions.
I can't figure it out. The only thing I suspect is the seam like in the rim. There appears to be a burn mark where the brakes are burning the the black paint faster. I measured that area and it seems no wider than the rest of the wheel.
It's weird that it's happening on 2 different wheels.
Shrug. Maybe wheels are out of true, and brakes are too close to rim.
@@RJTheBikeGuy I checked for both of those. I triple checked.
@@myscreen2urs Well I can't tell you without working on the bike.
I want to lace a wheel but I can't find rim tape around here. I read here (www.instructables.com/id/Duck-Tape-as-a-bicycle-rim-tape/) that I could substitute rim tape with duct tape, the kind that has a cloth-like structure. What do you think?
Alex Lopez I don't think it is the best choice. You can find cheap rim tape on ebay.
"Not sure if you can see it"...I coudn't see anything but!
I think I can see the dent. :)
got a dent to the inside on an alloy rim :( I guess no joy for me...
Bummer.
OR u could just get new breaks.
