- Red White and Blue is the new Orange and Black! After discovering catastrophic failure on a pretty sweet older Diamond Back frame, I had to go find a Trek frame at the local bike co-op to make a bike out of all the sweet parts and WOW! IT REALLY TURNED OUT GREAT! This one gave me the fits, but was totally worth it!

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.
“Pick a side so we can fight about it”, that explains the times we live in perfectly.
Exactly, because things have never been that way at any other time in human history. Pick up a book once in a while.
@@JohnBarrow1961 This statement is only in relation to our on lifetimes and how divisive and antagonistic things seem to be at the moment. You played your part perfectly 👍.
@@tone34despite the condescension, I do think they are right about people in most times of history being at odds for one reason or another. It only seems that way to us because we dont live in any other time but this one
OMG...the commentary on presta VS Schrader valves....PRICLESS, Bahahahahaha!!!! I dig how you talk about the comments section and how spicy it can get. "comments section" the hidden gem of RUclips. Good material down here! LOL Thanks for the content and good ole mechanical footage Mr. Farmer!
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.
This is the answer. This guy doesn't know !
The Amazon site in the UK has such bottom brackets for about £3 under the Mwave brand. I can't post links here but wouldn't be surpised if not on Amazon US site too. I'm guessing all sourced from China.
I used one of these once and it didn't work out that well. Always made a noise. Plus, I would be hesitant to sell a bike with such a BB.
Hey @bikefarmer if you want to try out one of those sunlight BBs, I have one I never used and you can have it. I’ll mail it even
@@marta150 thanks for the offer, but I’m not that into this idea.
Fork matches that frame perfect 👌
Just weld the BB into place. Calvin from Park Tool does it, so it can't be wrong!
JBI sells a BB that threads into itself. I’ve used it before with success. That frame was made in the USA I would’ve saved it.
The Bike Farmer appreciates our appreciation. And I appreciate that! Edit: I think - or else I'm just confused?
Videos like this get me excited to work on my own bikes.
Half my bikes have both presta and schrader tubes on the same bike.
to me the "old" shrader valves are much better. on presta it's too easy to bend that little metal thingy when you open them. the thing is that presta are thinner and most rims come with holes for presta. 😁and i don't wanna drill into my rims
It kinda looked like the BB on the DB was previously "chased and faced".. maybe another shop tried but failed.. regardless.. that was another awesome transformation!!
yes please, a deep dive into spoke protectors!
I remember a caad 4 i had that i liked a lot. The thing was old. I had an FSA BB bearing seize up. When i removed it, it took the threads with it. So now i have a caad 9 with same components except for a new shimano crank and BB.
Thanks!
I would say that you restring the cables. You may not have saved the frame but you rescued everything that turns some tubing into a bike. Nice!
I had learned you don't grease the tapers on the BB because of a risk of deformation when you put on the crank. Appreciate that you don't diss the kickstand.
Great vid!!! Love to see bikes get rehabbed:-). Repurposing bikes is a lot of fun and gives new life to an otherwise forgotten bike. ❤
Don't know if you tossed the orange frame yet or not, but Sunlite makes a "threadless repair bottom bracket" with a square taper spindle.. I'm sure there are others out there too
Would have been cool to see that Diamondback rolling again
Cheers mate
You know you can get a tap for rethreading BB's. I've had to do one before. Not fun but it's doable.
I bought an 820 used around 5 years ago and use it for everything. Single track, commuting in winter, erand running you name it. They are built like a rock.
I superglue cable ends when reusing cables. Holds it together well when going through housing.
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 always wondered what a person does to a steerer tube when it's too long. You offer me invaluable information. You are appreciated!
This is the first bike video I've watched that deals with the star-nut. Thanks, it's always been a mystery to me. 🙂
Can't decide. Am I watching because of the bikes or the sarcasm! Anyway keep going!
Thanks hey!
Dude! i love watching your videos! i have them on my tv while i rebuild and work in my bikes! I was hoping in the future you can do some suspension service videos, id love to watch them! anyways keep up the awesome channel and ill stay tuned!!
I’ve never serviced suspension! Crazy…
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
I live in Des Moines. A bike of that vintage I’d bet the shop was either Bike World, Barr, or Rasmussen’s.
You can see the Rassy sticker around the 10 minute mark. (RIP)
Give your one step bottle a good stomp. When it's dented it will get that last bit out due to higher internal pressure.
subscribed for the "social commentary." Let's fight about it!
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 have presta on all my bikes so I can use the same pump 😊
@@chrisfilby9678 Get a twin head for your pump, they're only like $6.
@@ltu42 Zefal HPX frame pump the only pump for me. ✊
@@chrisfilby9678 No floor pump? How spartan.
@@mattgies ofcourse a floor pump, but I find it cumbersome and heavy when strapped to the bike when I go for a ride so have been using a Zefal HPX when out on the road for the last 35 years. 😉
Thanks for sharing and teaching; I just bought 2 hybrids that I intend to turn into 1 good one for my oldest daughter (of course after I encourage her to watch this video).
Thanks! Have a coffee on me! Love watching your vids. 'Tis a shame about the diamondback frame, I was digging those colors.
Thanks hey!
Nice build! It’s the sort of bike that Trek should consider making… again!🤪👍
I was hoping you were going to include a close-up of the stripped threads in the junk frame. Thanks for the relaxing build.
I wouldn't throw the old frame away! get it welded and then bored out and re-thread the bottom bracket. After that either sell the frame separate or build another bike from spare parts. Good video by the way!
You got lucky with that! I always have wrong sizes or top pull front derailleur and have bottom pull cablling; that's why I snag cheap marketplace bikes and strip them for extra parts, lol
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.
These videos are great 👍. it's worth it for the comments alone! I also immensely enjoy the bike tool collection:).
Definetly one of the most informative videos!
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.
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.
Thank you!
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.
When you slid that new BB in and it rattled, I felt that 😢
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
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.
Best solution is to use a threadless bottom bracket. A few dollars more than a regular BB
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.
Have you ever tried thred coils for warn out threds...we used them all the time in the workshop !
Thanks!
Thanks hey!
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!
Great video as per usu! ❤ Your ad inserts and superthanks reminders went well with the flow of the video. Really enjoyed both your social commentary and your feedback feedback 😂 I hope your channel keeps growing - a bit more quickly even if possible.
Good use of the DB parts on the Trek frame. You saved one.
I'm new to your channel and really enjoy it, I've been buying and fixing up bikes to sell for a while, a little tip with spray cans that are becoming empty you can squeeze the can in so it makes a dent and it adds pressure so you can get the last bits of fluid out of them.
I think I like calling it rewiring (or wiring) the bike than you can say it's a modern drive by wire bike like the new drive by wire cars. Like how the bike turned out but really liked the colors of the Diamondback.
Riders in Wisconsin seem to love long stems. Every bike on here I've seen so far has an uber long stem. I know that was more common geo's back in the 90s but it wasn't the only geo's
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. 😉
Turned out AWESOME
A Trekback! Re-cabling in the rest of the world. Another good job done. A pre-owned bike gets some TLC and a future.
Music had me waiting for Charles Bronson to show up😀
His previously live was writing the score to soft core p*rn
I love these simple bikes you work on.. with the old school design.. that's what works.. either way I think the Trek is way nicer than the diamondback.. all the way from Canada eh.. not sure if I have ever seen diamondback in Canada... lots of Trek bikes up here eh..
There are saver BBs you can use
Velo Orange has BB thatll work with stripped threads. And: 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.
AGREED. I wonder how does he not know when he should of all people know that such things exists
That’s not something I’d want to put my shop name on then sell… that’s total fine if the customer opted for it. However this is something that will be sold to a client. This bike is a business card.
Thanks
Thanks hey!!!
My Trek came with Presta, but when my pump died, I added those nerdy brass adapters so my small electric pump would work! At my age, practical trumps classy! Oh well great video!
Frame is fine. Don’t you know, JB weld is the new press fit.
Sunlite makes a “repair bottom bracket” to clamp into striped threads and gives you a usable bottom bracket
1:24 - But we don't stop there. Oh No. There's even more! Sham-wow works on bikes, houses, and bike houses!
I worked in the bike industry for 25 years and never saw a threaded BB stripped. I really did think it was possible.
Untangling/detangling, rewiring/recabling, either way works. It depends on where you come from, and which ever one you've always heard it called.
we forget nowadays, a teen boy from 1970's would have asked for this bike for Christmas any day of the year ......
Came to the comments to see if people were arguing about greasing the square tapers. I was not disappointed. Anything you want to ever take apart again gets grease, no matter what Jobst Brandt says.
RJ The Bike Guy said it's a bad idea to grease the tapers ... and he did give a reason why.
@@staticdisaster Jobst said that if you kept torquing them, over time, you could split the crank eye. I have not heard RJ say why he doesn't do it. But I do like his channel.
BBI says for square tapers to be bone dry. Not even a finger print.
@@peterjv8748 What's BBI?
FWIW, that 2003 trek frame is aluminum too. Not quite OG steel, but aluminum is an underrated material for bike frames.
Takk!
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.
Im from the UK and i much prefer Schrader valves.
You could have used a Threadless square taper bottom bracket, they work fantastic.
Yea and that DB frame said it was made in the USA too. I would’ve saved it.
Bought a KTM bicycle in Austria last year, the tires had dunlop valves. Learn something everyday....
I am sooooo interested in buying a bikefarmer hoodie -- when will you open up a merch link?

Kidding. Don't flood your shop in TriFlow.
nice build nice bike👍
Preciate you Bubba...
Whoa baby! That’s amazing!!! 🌮🌮🌮🌮🌮🌮🌮🌮🌮!
OH NO you greased the tapers?!?! The crank arms are going to explode on the first ride!!!
It’s clearly not Shimano special grease you can kiss the manufacturers warranty good bye.
Lol. The best mechanics I have met all say square tapers are to be bone dry. Not even a finger print.
You can get an "universal bottom bracket," it's just a bottom bracket that threads on itself and kind of pressure fits on the broken frame threads.
How many times is he gonna sell the same bike? Answer: As many times as it comes back! Because, if it comes back, it loves you.
So I’ve heard this guy say before that if you see a cycle shop sticker on a bike that it’s quality. I delivered oxygen to a junkyard today and saw an old bike there. I walked up, looked at it and it had a bike shop sticker on it. I picked it up and it felt rock solid and light as a feather. This was at a JUNKYARD!! 😂
People throw out quality bikes all the time
@@bkefrmr That’s crazy!!
@@herschelsquirts2338 not really. It’s super common for people to have extra bikes in their garages that they don’t know what to do with.
What causes this bottom bracket failure? Riding the bike around with a loose bottom bracket ? Or was it low quality mfg ?
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
Well think the buyer well come innfor Regular Tune ups
this one came out looking great. my touring bike was a similar color but sadly I had to use rustoleum to rehab the frame.
Pipe cutter for the tube cutting? Got one for like 20 bucks at the local box store
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.
When I used a pipe cutter it left a ridge that needed filed down before stem would go on. With saw guide I have no problem
Man sucks seeing a Diamondback go to die, but at least that Trek got new life and i looks good to, and as far as those sunlight bbs go, they are junk, used one a awhile back and they are no good.
Marvelous build...
I was eagerly awaiting the bike farmer jumping stumps and doing a backflip with this bike. What a disappointment 😂
Nice job Andy
Do you “ope” to yourself even when the camera isn’t on?
I like general purpose bikes
Your Blade on your Hack saw might be Dull
Is this Trek 820 frame really CrMo steel, not aluminum?
Good Stuff.
I enjoy watching your content. I miss it too.
Ah so that's how you set up v-brakes!👍
Good watch sir. New subscriber.
Do they make HELI coils that would fit the bottom bracket threads ?
