Vintage 1992 Specialized Crossroads Hybrid Rebuild

Well hello, I've just joined this forum to learn about this bikes as I start this new hobby/exercise. I have attained a specialized crossroads trail hybrid from my uncle since he moved on to another bike and decided to Build a bike according to what I want. It stated as a junkyard build but quickly turned into something a bit more

This is what I began with:


I started looking for CHEEP parts but I figured, since I will be using this for at least a 20 mile commute let me make it reliable, I ended up with these parts:



Then I decided well...I'm already knee dip might as well paint it! So I went and bought these:



Still waiting on the wheels/tires/tubes to arrive.

My frame had a bit of rust on a few scratch areas so, I had been hearing about oxalic acid and its love for rust. I decided to test it and took one of the few parts that came with the frame and it went from rusty as hell to this:



With that I decided to make a a nice acid tub in my garage:


I started with the bottom of the frame:

Then rotated per side of effected area.

As I had the frame bathing I started work on stripping the fork:

From this


To this:


Then it went it for a quick dip, and after a soapy wash I primed it:



Now just waiting for it to dry. The frame is almost done being derusted and will begin stripping the paint soon, I read that one of the forum members makes decals? I wanted to keep some but they got hit hard with the rust, so that's not happening.

Welcome to C&V!

Well, you've a good project to start your building with. From your first photos of the frame before, the original paint looked fine, so an Oxalic Acid bath and a touch-up and polish might have saved you a lot of work - but it's a personal thing. That blue will look good, but rattle-can spray paint can be very fragile, compared with the manufacturer's finish. Allow plenty of drying/curing time in a warm environment (weeks rather than days) between primer and colour coats, colour coats and clear coat - and after the clear coat and it will harden off and last a lot longer. That's my experience of spray can painting frames, anyway!

New components are obviously going to last you a long time, but are a more expensive option than hunting down a 'donor' bike or individual parts in good condition as required. They are also easier to obtain!

Please keep posting pictures of your progress and don't hesitate to ask us any questions you may have - the guys on here are immensely helpful and friendly. The experience you gain will be helpful in the future as this hobby is addictive - especially when interesting old hand- built lightweight racing bikes become available!

Good luck!

I suggest you clean off, mask or better yet. remove the crown race of the headset that is on the fork. Bearing surfaces do not like paint when in operation.
Same may go for the headset parts in the frame, but I am not sure what you are or are not doing there.
As you said, your are in deep. A local bike shop should be able to help you, and you may need them to help install the crankset anyway.

I have a similarly aged Crossroads that I did a dropbar conversion to. I ride it every day and it is pretty good with drop bars and bar end shifters. My biggest problem is the lead crankset, but you seem to have no crankset so you can get a much lighter one!

Looks like you are off to good start. As other have said before deciding to repaint next time try the OA bath first. You'd be surprised how much you can revive an old rusty frame.

Yep, the frame had been soaking in an oa bath overnight. REALLY needs a paint job lol...the first pic didn't show how bad it needs one so I understand where you are coming from, but here is the aftermath of the oa bath:









Those were the worst spots, everywhere (and I mean EVEYWHERE) there were scratches of rust or speckles.

Yea I saw that, I thought it was part of the frame :l I took the top half off and left the bottom, I was going to put some lube on and hope for the best if not I'll just get another crankset. I am a bit stubborn DIYer so everything will be done by me. Most of the time I read/study enough about something before I get my hands dirty, but sometimes I miss stuff too, but hey who doesn't
