Here's a tip I learned when I was a hobbyist blacksmith: Reverse your hacksaw blade so it cuts on the pull stroke. Pushing uses mostly triceps and pulling uses shoulder and back muscles. You can cut for longer periods without fatigue and with less wear and tear on you. Be nice to your body. You've only got one of them, so make it last. :) Love the channel.

[@InTheCave-mx7jc]

When the BB threads are shot, but the rest of the bike is good, Sunlite Threadless is a square taper BB that threads into itself instead of the frame. For less than $30, you can save the bike and not have to swap everything over.

I think I'm one of those very lucky fools who has the riches of bikes. I restored an 1967 Phillips 3 speed (Raleigh frame). 'Have a light weight aluminum hybrid, an entry level mountain bike (great for gravel) and a commuter e-bike. I'm no longer allowed to enter debates on Shrader or Presta valves and disc brakes vs rim brakes or mechanical disc brakes vs hydraulic systems since I now ride one of each. No arguments, they're all good. One top of that, there's a terrific independent bike shop in town run by a great guy and unknown genius who repairs bikes and can find parts for just about anything! We count our blessings.

[@finncarlbomholtsrensen1188]

As a first after buying a new Brompton, folding bike in 2019, I gave all of its painted frame an "Auto Polish", and found out that the small pieces of clear tape "protection" from the Factory had been near worn through to the paint after a few folds! As I like my bikes to look like new, I found all the possible "protection plates" and a cable shield from China and it still looks like new today, and very much lighter than the original, from the amount of possible carbon and titanium parts I also found in Asia! I also changed my crank to Ceramic balls and titanium. Finn. Denmark

i am also a bike flipper, and one time i had that one cannondale, looked so good but had a seized bottom bracked. well... 3 hours later then... someone glued the bottom bracked in... it was done for me at that point, i just reused all the other parts and build up an older Rosè Frame. so whatever :D

[@lucafwn]

Three bikes here: one with Schrader valves, the other two with... Regina valves! - Italian standard, same size as Presta, can be replaced with a Presta tube. When I bought bike #1 it had Regina valves in Schrader rims. I changed the tubes to Schrader for that reason. When I bought bike #3 I found that it has one Presta rim and one Schrader rim. I stayed on Presta, using a DIY adapter on the Schrader rim (I found the recipe on a You Tube video): one of those convex washers you find in V-brake pads - the right internal diameter for Presta, the convex part fits the Schrader hole. So far, so good.

[@ltu42]

Schrader valves are common in Europe. On the bikes that have a steel frame, mudguards, 3 speed Nexus internal gears, threaded heatsets, etc. Presta only on bikes for sport.

I would be tempted to try to figure out some way to repair or reuse the Diamondback frame since it was such a nice looking alloy frame.

[@mattgies]

One hack is to re-tap it for an Italian threaded BB, which has a slightly larger thread diameter. The shell width is also slightly different so some spacers may be required. Expensive and "at your own risk" since you're removing material from the most stressed part of the frame.

[@bkefrmr]

Thank you!

[@paulmaurice4491]

I had this same issue with my gt timberline, i filled the threads with job weld and retapped the bb shell it held up for years. And yes I drink every time you say “ope “. It’s my second favorite pastime!

[@6479rob]

What causes this bottom bracket failure? Riding the bike around with a loose bottom bracket ? Or was it low quality mfg ?

[@staticdisaster]

The bottom bracket cups probably got loose and a person who knows about bikes would feel the play and stop riding immediately and either tighten or replace the bottom bracket cups or cartridge. I bet this person just kept on riding and the cups unthreaded more and ruined the threads

[@nalaunobelmoura4000]

Is it possible to bore and do a sleeve installation in the bottom bracket tube then thread it if that's a steel frame? That would be an interesting project

[@davidhakes5141]

That would be my question, too. It would be a shame that a perfectly, structurally sound bike frame couldn't be used, because of the threads, or the lack there of. If that surface could be built back up, or the threads could be re-chased to receive a larger bottle bracket. I didn't see any cracks, or any other structural issues.

[@staticdisaster]

Best solution is to use a threadless bottom bracket. A few dollars more than a regular BB

[@6479rob]

I was wondering about that myself but too every bike shop of any age normally has some older bike parts thay can swap parts from. I am sure in time thay have to make a run to the scrap yard old junk at some point is just old scrap metal.

I'da been looking for a way to evenly add a bit of diameter to that crank and then use a tap to thread it, thus eliminating the play. Thin pipe, Coke cans, that sorta thing. 😅 And not quite as wide as the old threads, so as to give the tap threads to start on.

Why not use a pipe cutter to cut the fork? I've used one to cut a a few fork steerer tubes and it does a great job with very little physical effort required. It seems to be a much easier solution than using a hacksaw unless the fork is carbon.

That steer tube spacer, though! It's not the same outer diameter as the longer one! Or, am I the only one that that bothers? While I'm at it, you misspelled "routine" in the title. 😉

[@jstar1000]

I get that you run a bike shop and time is money etc. but when I restore a bike for my own personal use i completely disassemble the entire bike, any and everything that comes off the frame comes off including the headset cups etc. I then wash, polish and wax the frame and fork with car products and one by one take each part out of box I put them in and clean polish lube and re-install every part and replace anything that is trashed. When done, the bike is as good as it can possibly be at that point. Obviously that is a lot more time and effort and not something a bike shop would typically do.
