Positron400

Hey!

This is the continuation from a thread in the Mechanics section from a bent mixtie Frame. I was able to bend it back into shape and started putting on some stuff. Thought I share the build progess in here.

I used some rust converter on the worst parts of the frame and tried to polish it a bit. Due to the state the frame was in, there was not much to be salvaged. When i used the turtle wax abbrasive compound, the decals didn't like the treatment I basically removed quite some colour from the blue parts. Live and learn i guess
Currently i've spaced the rear triangle to something close to 130mm and put in a 700c rim with a 10sp 11/34 cassette (Acera 9sp RD [i think..]). For the crankset i've "polished" and reused a triple (400 LX) from a Rockhopper build with a 38 teeth chainring (Stronglight 110 BCD).
Next up, downtube shifters and brakes. (center or sidepull, unsure atm)

Turn's out, I lost the seattube bolt at some point, so need to source one from the hardware shop

Quick progress update:

Put on some gear cables with a downtube friction shfiter. Polished the front and rear brakes w/ some Autosol. Cleaned and regreased the headset. Put on a rear tyre (700x35c Schwalbe G-one)

coming right along

the backside of the Weinmann 605 brake calipers may exhibit a date marking -

Pretty much done at this point . Only need to add handlebare tape and then take it for a testride.
Seatpost and saddle will be replaced soon too because 1.) ugly 2.) too short

Generously lube the rear brake cable where it loops down. Water tends to collect there.

thank you for this update!

good to see you found something to use as a seat binder

did you mount a front gear mech because you may wish to go to a two plateau drive train?

do you know a date for the bike?

were you able to get the laterals straightened out?

I like your bike.
No need to ask why; it is just because sometimes they can have a useful 2nd life.




Lots of people don't get it, or simply avoid the 'hassle'.

A small rubber boot on there will help,

Positron400

you are most welcome It's always fun to build up bikes from a frame.
The seat binder is a remnant from my Rockhopper build - missing the handle, but not something a screwdriver cant fit

Yea, i plan on going 2-by at some point but, mainly because the chainring is not a narrow-wide and i am afraid of the chain dropping.
No sorry, no date for the bike yet, but i can check the BB for the serial number, if that would help.

Nope, laterals are still bent, but not too bad - so i don't really mind

Positron400

Thanks - tbf, it was way more of a hassle than my previous builds, due to the fact that the frame was quite bent. But i just loved the colour and have never built up a mixtie frame before.
Your frame is a beauty!

an excellent reminder!

have had people bring me lady frame bikes to work on where the rear brake cable was solidly rust-welded to the cable casing

Another update:

Removed the decals from the wheels. Never was a fan of the white-red, or a fan of gaudy, large decals in general - esp. not on rims Now the aesthetic is cleaner. Also "tried" and polished up the mudguards. Mediocre sucess there since i cba to remove all the scratches with sanding paper. I just went over it with som autosol to make them more sparkly.
Temporary "bar tape" put on - basically elictrical tape. Horrible feeling when riding, but given that i am not sure what colour of bartape to put on and that i might/likely will be switching to aero levers, i didnt wanted to waste a 40 USD Supacaz, just to remove it in a week for something else.

First ride today: Cranks came loose because they weren't tightend down properly. So did the pinch bolt of the RD. Rear mudguard is a rattling mess. Seatpost waaaay to short (new one ordered).
I like this bike

That's awesome!
I am so adding this to my mental toolbox.

Beautiful color! Good job straightening the frame. I thought it was a goner for sure. I guess there is something to be said for low end mild steel tubing.

Haha, thanks - Yea I wasn't so sure i was going to be able to straigthen the headtube after some failed attempts. It is considerably lighter than my other commuter bikes (~11.3 kg) and should be durable enough for anything.
