I've been there brother. I was in the middle of building my current gravel bike and the handle bars swung around and dented my top tube. I completed the build and still ride it almost everyday. Every time I look down at the dent I get a little aggravated. We learn so much from our mistakes. That is how we grow. I have no doubt you will continue to do great things. You went above and beyond and it paid off. Amazing Job Bruce!!

[@BruceChastain]

well luckily my dent is near the seat post, so I don't see it while riding :) . thanks Teve

[@Nick87899]

Was trying to wipe dirt of tires on my brand new Dr. Dew and it slipped and whacked the head tube on concrete steps 😢 luckily only a nic in the paint I feel the pain

[@marcmasson5958]

Really nice job on the restoration of a great-looking vintage Miyata. Congratulations. I have a project right now with a similar stuck seat post situation on a 1970's bike that is being converted from a 10 speed into a single-speed. After attempting to loosen the seat post in various ways with no results in sight, I simply cleaned it up and left it at the height it was stuck at. With the seat I have installed, the seat post at the exact position for the rider ... lucky

[@BruceChastain]

haha that's awesome, and the result isn't much different than mine, because where the dent is in the seat tube, i have to run a very short seat post, so you really can't safely raise it up any more than it is now.

[@mauricioorantes9809]

Thanks for,hanging in there and saving this bike. I have a soft spot for Miyata’s. As I watched your video it was like watching an experienced surgeon saving a life. A patient who was in a bad place and you got to work. Almost surgical. Battleship grey is a cool color. I want one but with a “pop” of neon to create depth.

[@BruceChastain]

thank you Mauricio! I was also considering going with a second color, but being I already had these blue wheels, I was afraid that adding anything might look a little over the top, or like it's trying too hard.

Was a bit surprised when i first saw the different color at start of the video. But then after seeing what followed, it made sense. Good job fixing it. Also, pretty sure you're driving someone crazy with that drivetrain comprised of campy, shimano, sram, microshift, and others. I personally love it. Whatever works.

[@BruceChastain]

thank you Oscar! yes I was also considering how odd the mix of components are. But really it's just a combination of what I already had in the parts bin and what I could buy for a reasonable price. I should really do a price breakdown and post it in the description, I'm sure the question will come up anyway.

[@mfsibbald]

You are a legend. You made a mistake of being in a hurry, I know that feeling all to well, and f'd a classic frame up that deserves better and then (legend status) you cowboyed up and gave it the love and set it back on its destiny.. Props and respect!!!! You are a Champion!!

@@BruceChastain Anytime! I retro-moded a few bikes last summer and donated them. If you are a bike-lover like me and you are, and love tinkering on them, there is nothing more satisfying than to take an old vintage steel-frame bike and bring it back to life with a fresh coat of paint and some new, updated components. Though the bikes may be moded-out in the final restoration, they never seem to loose their vintage character.

[@BruceChastain]

yes and this one really does still seem vintage to me, I think because I kept the downtube shifters and quill stem, it's not light and super fast, but rides so nice.

[@BruceChastain]

As always thank so much Eloi!

Nice! A couple of questions... Wouldn't it be possible to pull out the dents in the top tube like on a car dent repair? Good idea with the 9 speed 1x9 - great with the link to the Microshift cassette - i'll be using that... but I prefer STI shifters instead of downtube shifters - do you know any STI shifters that work with the Sram derailleur?

[@BruceChastain]

Thanks Andreas! I did contact some people on suggestions for the dent, even posted on a frame builders facebook group, the suggestion is to first try to actually push it out with what's called frame blocks, which I did you can see at one point in the video. Then either use a metal filler or bondo to finish it. In terms of the STI and Sram, I might be wrong but I believe any will work as long as it matches the number of cogs on the cassette. This is because the distance that the derailleur moves is only dependent on the shifter, not actually the derailleur, I mean the distance of the increments. Hope that makes sense.

[@jlnprssnr]

Great result! I presume the downtube shifters are not indexed? How do you like them with the nine speed cassette? My project idea was a 1x10 setup with downtube shifters, but it's near impossible to find compatible indexed shifters apparently and I've never tried pure friction shift so I'm unsure about that. Maybe bar end shifter is the way to go, though I really don't like the looks of those.

[@BruceChastain]

Thank you! Yes you’re correct they’re only friction. I like the 9 speed cassette, it’s my favorite, I think it works good with the friction shifters, although I’ve never tried a 10 speed.

Six hours of hacksaw?! Man that's dedication! Nice rehab, I enjoyed watching it.

[@BruceChastain]

thanks Brittany! Yes well the thing is, you have to be very careful because if they saw blade isn't perfectly parallel with the seat tube, then it can start actually cutting into the tube and not just the post, so it's very slow cutting and a lot of stopping and checking as you go.

[@timothydoyle8269]

I have a univega nuovosport pretty much similar frame- looking into DIY painting the frame myself. I noticed you didnt completely remove the initial paint layer. How did you approach the paint job? Just simply sanding down to some extent then straight to spraying? I see other videos where people will bring the frame down to bare steel, does it make any difference? Thanks

[@BruceChastain]

I've painted a few frames now and my method that I think works best is this: 1. Sand down to where the surface of the existing paint is very thin or even the paint is gone. Don't worry about removing it totally, the original paint will actually sick better to the metal likely then what you'll apply. 2. I don't use primer, I use a 2 in one primer paint, and I've been fine like that. 3. Use the 2 part clear coat, do not use a regular single part, needs to be 2 part clear. And know that whatever you have before laying the clear down is what you're going to get in terms of the surface finish. The 2 part clear really just creates a glossy hard coating of whatever you already have. That's my cliff notes from doing a few frames.

[@timothydoyle8269]

[@Not_Sure_]

Great video. What made you decide on the 42T 9 speed cassette, with the 38T crank ?

[@BruceChastain]

Almost all my bikes are 9 speed, so it’s easy to interchange parts. As for the 38x42t, well with that I can do a decent at climbing, and on the other end 38x11 is faster enough for me, not sure of the top speed but for sure can cruise around the low 30s kph.

[@Not_Sure_]

@@BruceChastain I thought you were in Florida, are there any hills to climb in Florida ? Forgive my ignorance, I've been to Florida a few times, and I don't remember seeing any mountains like in southern California. I have a 1 to 1 ratio of 34t/34t as my lowest gearing, on my "nice" bike. And I also have a heavier Schwinn with 3x 28t front with 8x 32t rear. They feel about the same on the climbs.

[@user-ve3gh5xg9q]

🚲 gold 👏

[@jamesdelgado2009]

I have had success getting a stuck seatpost out with liquid nitrogen and a heat gun. I do this first before attempting any other kind of removal such as a liquid penetrant or use of force. 1. Place the frame in a stand upside down, seatpost pointed down. Make sure that any holes to the inside of the post are plugged so that the liquid nitrogen does not run out. 2. Heat the seat tube gently with the heat gun. This will expand the seat tube metal. 3. Pour the liquid nitrogen down into the bottom bracket, and down into the seat tube. This will contract the seat post. The thermal difference between the post and seat tube will generally shock the seat post free, sometimes with a popping sound. However, I have a mallet ready to quickly knock the seat post out once I either hear the pop or I give it a few seconds to react. You don't have to really get the seat tube any hotter than a temperature that is uncomfortable for you to touch and hold. Anything hotter than this is just excessive due to the super cold nature of the liquid nitrogen. If done correctly, you won't damage the paint. If there are some nearby decals, those might be damaged.

[@keithbillett6678]

Where does an average person get liquid nitrogen in the amount needed to try this technique my self.

I have a MIYATA Pro Aero which I bought new. I did an upgrade and remodel in the late 80's . to include braze-ons and a repaint. Currently mostly Sun Tour Superbe derailleurs, brakes and bar ends.. Love the bike but I want to do something more interesting with it to make it more useful rather than the all out racer it was intended to be. Done with my "racing" days. I am curious about your gearing ; what restrictions, if any, on the 11/42 - 38 ? And would it be possible to use the bar-ends ? Excellent video, crazy good bike. Admire your ingenuity and tenacity.

[@BruceChastain]

thank you Jeff! As for the gearing, for me it's totally fine, but if you're more on the racer side or if you like getting a lot of speed going down hills, probably you'll spin-out. Yeah bar-end shifters should work totally fine. I'd actually like to try to do that some day.
