MY conversion project
Well here it is. The old skool 12 speed that I am going to convert to a Fixie.
Will initially use the road cranks, and put a standard chainring on instead of a bio-pace.
I have ordered a set of Miche track hubs, and have yet to decide on everything else!

Good luck with your conversion. Finished my conversion and loving it. Working on getting pix.

yo I think you may have just identified my bike. I got the same gradient paint scheme, same downtube shifters and biopace rings, same goofy fluted seatpost, and lugs look exactly the same.
Does that sticker on the seattube happen to claim mannesman tubing?

Try the little by little approach. Get it minimally functional to see if you like it.
Fixed is not everyone's cup of tea ... nothing wrong with that.

Yes 105 components, although quite old and going out the door due to the fact that well.. they aint needed.
This bike will be my commuter in Hamilton, which is rather flat.
I might try the bio-pace rings, is there a way that I can get the deraileur to work as a tensioner? - Wait that only works with freewheel SS.... haha
Edit - pic served its purpose - thanks for heads up.
The frame is CR-MO.
Yes this is an Avanti Ultra, made by a NZ company probably back in the 80's, or early 90's at best.
Lunigma - did you need any sort of tensioning device at all? SB gives me the thought that I don't need one...
Regards,
Brendon

Those dropouts will work perfect. You will not need to use the old derailleur for chain tension.
You will not have any problems with the dropouts.
These articles might be of worth to do a quick read:

https://sheldonbrown.com/deakins/how-...onversion.html
You probably have a good idea of what it takes to do a conversion, but, hey, you might learn something new.

Biopace rings are not being produced anymore, and have a somewhat faithful following, so don't throw them away.
That paintjob is awesome. So are fluted seatposts. I think track drops on that thing (even though it's a conversion) would look sweet.

Keep the biopace for a while anyway. It is interesting to watch the chain move back and forth without losing tension.
You can fix it up single for now. Just remove all the shift stuff and pick a gear that gives an OK chainline.

The rear rim is shot to hell (cracks etc) so I need a new wheel before I ride, so I might as well do the whole drive train in one go.

I had old Dura Ace with BioPace rings on the bike that eventually became my conversion, and I didn't even try it before putting on a round chainring, I just assumed that it would be whack.

Therefore, everything would be peachy. Ever watch a geared bike w/ Biopace? Did the deraileur move back n' forth picking up slack with every rotation of the cranks?
I didn't think so.

Started the strip down tonight! here's some pictures.
Whole bike just as I was starting to attack it,
Biopace crankset (inner ring is a 42T which will be perfect for gearing...
All of what I took off tonight.
Any ideas as to what I can do to the old mounts for the DT shifters?

I use a biopace chainring on my fixie. I like it a lot, but learned something
VERY IMPORTANT- when you bolt on the rear wheel, setting the chain tension,
make sure the Biopace is placed in the 'loose' position. (pedals facing forward
and backward) That way, the rotation will slightly tighten the chain then return
it to your set tension. Do it the other way, and the chain may bounce off the
gears when the ride gets bumpy.
