I found a Salsa 425mm in stock at a local bike shop (CAD$113 with tax), bought it and installed it tonight at my coop, didn't knew it was that easy to work with threadless forks, took me about a hour
Waiting for my new crankset and chainring to get rid of my derailleur..

Thanks for the help and nvm for the thread jack
