Vintage Peugeot conversion help and tips please

Cant help you on the Pug front, but i run a front mechanical disc - i think you would have problems fitting those forks unless you converted to an aheadset, which might end up costing a wee bit. Anyway heres a pic of my brake set up, similar to the one before in the thread - didnt realise anyone else had done this, though i know Flickwig has done since with a disc too.

Slightly off topic but others may have an interest in this.

Nice bike set up here, Vinyl. Is it set up as a trick bike? I've done the same front brake cable routing on all of my previous bikes so that I can bar spin them. Is this what yours is set up for? I also know that a lot of the top loading brake calipers (standard ones that mount via one bolt in the fork crown) foul the frame when the bars spin, is this one of the reasons you've opted for the disk break?

I'm sorry to say that my Pug is now dead - RIP. It lasted well, and to exigetastic, I ran my Pug with ALL orginial parts for some time. I literally took off the gears. I managed to line the chain up on the largest cog on the front and the one closest to the right gearing on the back (good net programme called 'Rabbit' for calculating gear ratios if you need it) and it was near enough straight.
