Just did this on my Masi Nuova Strada after a careless driver took me out. Worked like a charm and didn’t even crack the paint on the frame. Looks as good as it did before. Took about 275lbs of humans bouncing on the Columbus SLX tubing to get it bent back into shape. Steel is REAL! Thanks for the video and Article link!!!

[@dawbool9552]

I like the way you go straight to the point when tackling a new project. Again good job, thanks!

[@JeMasLT]

This winter I will reassemble my e-Bike. And your channel has everything I need. Thank you man.

[@acewilliams7917]

Guy, you're the flipping man!! I just bought a bike with the same problem. Thanks for the knowledge, It's priceless.

[@TechnoShamanism]

Man, you are the BEST!!! Thank you for all the work you put into these videos, your channel is an incredible repository of knowledge & learning!

[@frazure2857]

When I got my OCC Schwinn Stingray the rear part of the frame was bent inward.. did this and it did wonders. Thanks so much! 🤜

[@murray1234ful]

Bob Jackson! A proper Yorkshire frame

[@thomasoeler5157]

great job! i wish u could rebuilt more old school roadbikes. keep up your great channel!

[@carloszambrano3227]

Buen trabajo, en mi bicicleta de ruta Miyata le hice un trabajo parecido, el mismo tubo lo llevé al sitio golpeando con madera y un mazo de goma y quedó excelente. Saludos desde Mérida Venezuela..!

[@fclancy2724]

It works. I noticed my frame was bent when I took the dynamo off it. I stood on the seat stay and bounced up and down and now it is straight again.

[@BikeItUK]

Another great and helpful video! Loving the Pepsi stack...I understand now. All the best and if you are ever over in the UK look us up, Andy

[@RJTheBikeGuy]

LOL! :D

[@Piers811]

Thanks for this video RJ! Got an almost identical dent in an old Raleigh frame, but my puny 68kg/150lbs weight (plus about 5kg in a backpack) wasn't enough to bend it back. Any ideas?

[@crypttonite]

cool vid, have a bend in same spot. out of thin air the other side seat stay became too close to wheel to clear brake pad, weird. Alignment between chainstay was good near bb. Anywho did the 2x4 chair routine & got it p close, needed a fraction more & somehow it was then out of whack. Put too much weight on lever, body weight & bent non drive side very far created a crease & a ridge. Gently got back, it was all over the place, crank clearance. Now it’s straight. Hopefully bend doesn’t develop a crack. I suppose the other tubes prevented it from busting. Wondering how the seat stay became out of line? Twisting from seat too high maybe, torsion?

[@ivanclaurencemdocot7965]

Mine have the same prob but just bend when i bend it back does it have chances to be bend again?

[@Osstovar]

Hey RJ and a big thanks to you man, that sharing your great experiences with us👍🏼 Would you make a clip about how to fixing a bent or realignment of a twisted Seat Tube, please?!? I’ve this problem on the ST of my ‘1984 PX10’ and its ‘531pro’ frame…🤔

[@pixiedixie3682]

I got 1970 " Bobby" is a joy to ride !

[@SMidberg]

I have a 1985 ...like a Rolls Royes.

[@MitchCrane]

Note to viewers: it doesn't have to be diet Pepsi. Any Pepsi product will do.

[@RJTheBikeGuy]

LOL!

[@flortega85]

Mitch Crane ONLY DIET PEPSI! OR RJ COLA!

[@zyfeislife8771]

whats your opinion on using a straight edge along the upper seat stay to help with alignment? just bend the lower part till the straight edge touches both upper and lower seat stay.

[@separatysta47]

Hello I have a question, if I have an old steel frame with headset 1 inch can I set up a 1 1/8 carbon fork?

[@RJTheBikeGuy]

No. kzbin.info/www/bejne/hXnGm5tqhJdjodE kzbin.info/www/bejne/eXqxm6ifqNV6a8k

[@davidcanseco3104]

Gonna have to try this on a bianchi campione bike frame I just got from eBay, seller didn't list that the frame had a bent seat stay 😑

[@Boogie.VanMan]

When using the frame tool to check the alignment, how do u know ur taking the initial check from the correct side?...as in, how do u know which side is the factory-straight side?...maybe they´re both out a bit...or something...noob question probly..!

[@SuperKakaras]

... eeend, I love this channel🙏

[@tinygreen2110]

I havent done it yet but it seems really helpful, thank you in advance

[@RandyDarkshade2]

I had a similar issue with my SUN Solo, but it had bent where the brake mount is, so I was able to lay the frame down and pull the seat stay at the wheel drop out.

[@Albanez39]

Even if the bent tube was repaired, the steel structure is weaker than it was. On my last bike, the seat stay started breaking, just a few centimetres over the brake mount. The bike held fine, it didn't seem to ride diagonally or anything, but with time, the chain stay on the same side started breaking. I decided it was time for a new bike, and thought about welding it, painting it, fixing it and selling it for cheap. I believe the seat stay started braking because of my chain lock. The locking mechanism of the chain would be hanging right on the breaking spot, and every time I hit some minor pothole, I'd listen to the chain slam on the seat stay. It seemed like minor contact, and it was...but after thousands of hits, the seat stay started cracking until I noticed it and started keeping my lock in my backpack... When I disassembled everything I was stunned. Both of the stays were broken almost completely, and just a thin section of the tube was holding the entire weight. I welded everything and bent them in place. They look pretty well now, but I haven't been able to find paint stripper anywhere in my country. I want to paint it like new, replace some components and sell it for about $200.

[@anandagarwal3335]

hi, i like all your video as they are very informative... i need to ask that how to repair the frame area (bolt cannot be tighten enough as the builtin clamp is broader and does not hold properly)where the seatpost goes in.. please reply.. thanks

[@RJTheBikeGuy]

Sorry, I can't really give you solution without working on the bike.

[@homunkoloss6782]

is it safe to remove a dent like in the video and then bend the frame out again from 126 to 130? or will the bend reappear at the same spot?

[@RJTheBikeGuy]

Probably not a great idea.

[@homunkoloss6782]

@@RJTheBikeGuy thanks for the reply :)

[@harrymaccycling]

Hey, love the video. My rear triangle got bent on my steel frame a year back, I've bent it back twice, I feel comfortable riding it around town but do you think it's safe to load up for a bike tour? There are no cracks, just slight bends where the tubes meet...

[@RJTheBikeGuy]

Probably be oaky, but makes me wonder why you had to bend it back twice. Maybe too lightweight of a frame, or some other issue.

[@danfuerthgillis4483]

"I came here for the Pepsi boxes" lol. Awesome frame!!

[@geoffpoole483]

I've got a Bob Jackson audax bike. It's my pride and joy.

[@geoffpoole483]

Hi RJ, I've just been fitting V brakes to one of my bikes. All was going well until I found one of the brake arms had a very limited range of motion compared to the others. Could this be a sign that the frame is bent? Greetings from England.

[@tinyexplosions]

Tried this method with a 531 ATB frame, could barely get it to move a mm (and I'm a big guy who was holding a heavy concrete slab). Just goes to show how strong steel frame bikes are!!

[@neilfroggycrompton2466]

+rjthebikeguy did applying foot pressure crack/flake any paint off the frame?.

[@RJTheBikeGuy]

No.

[@adamh7947]

Cool frame

[@LvcianoN]

Wow, RJ! Sounds brutal and scary but, man, it works! Stepping on a frame to fix it definitely hadn't crossed my mind. That is a pretty nice frame, what time frame is it from? Build video coming?

[@RJTheBikeGuy]

Seller said 80's. Yeah, I know it looks rough, eh.

[@FedoraQuilava87Music]

can you show how to get a bend out of a fender? ive got a 1965 schwinn breeze. and thats the only problem.

In aus i got a cannondale f700 cad2 with the same dent its an aluminiun frame is there any way i could repair it

[@RJTheBikeGuy]

Do not not this on an aluminum frame.

[@montrgomaus]

I have a bend that is concave toward seat tube? How to fix that please?

[@RJTheBikeGuy]

Probably the same way. Carefully. At your own risk.

[@pixiedixie3682]

You can use body work car paste , to fill the gap

[@leqin]

RJ - it would have bent back quicker had you used Coke sooner than Pepsi :.) - great video as always.

[@that70sschwinn]

Nice job

[@Bogoizbrania]

Interesting, I have the same band on the same spot on my vintage Peugeot frame.

Maybe once I learn how to do it.

[@DANILKARRA]

Тоже самое. Я уже на парочку сделал русский дубляж

[@thedowntownbikeshop9910]

Is it me or does the down tube have a slight buckle in it?

[@RJTheBikeGuy]

It's an illusion. The is a small stop on the bottom of the tube for the clamp on shifters, and small scratches on the tube in that area also from the clamp on shifters.

[@thedowntownbikeshop9910]

Oh good. I had a frame come through and the illusion was the opposite. Paint looked great, no dimples or cracks. But upon looking at right angle you could see a slight buckle near the head tube.

[@Albanez39]

This is why I fucking love STEEL!!!

[@bigfootandbananaman4746]

Cool!

[@duanescarborough8297]

Thanks for the very informative video. That was a minor bend, and a relatively easy repair, so please explain why you say that the same kind of repair could not be done on an aluminum frame. I've straightened much worst bends on aluminum with good results. Some would say that your example frame would have to be trashed if it had been aluminum. I disagree.

[@RJTheBikeGuy]

Cold bending aluminum makes it weaker and prone to breaking. Not safe.

[@danielkostovski4517]

how heavy is the frame? And the total weight of the bike?

[@RJTheBikeGuy]

I will have to weight. As far as the whole bike, it depends on the components. I just got the frame.

[@johnmartin9907]

Might be easier with a pencil thin frame vs. Tube aluminium

[@snarkygnome619]

Meanwhile I have bent my mtb alu frame seatstay and also seattube(!). Time to weld some reinforcements and finally retire the mtb for a city bike. 😂

[@rectoreyes4112]

What will happen when you just gonna ignore it?

[@RJTheBikeGuy]

Then the frame is bent, and out of alignment, and the bike will ride funny, maybe dangerous, etc, etc, etc.

[@ReclusiveMountainMan]

You like Diet Pepsi and Pepsico products. It is clear. Nothing wrong with that. Just noticing as a faithful viewer.
