i don't want to use my xc bike for anything very big so i want to convert my back up bike to be my "big" bike. it is 1993 Cannondale M800 "Beast of the East" set up. currently the only major changes from it's stock package or how i bought it is a SPIN rear mag rim (Spin is no longer in business) and XTR V-brakes (new within the last 3 months). it still has the Pepproni fork so it is completely rigid. I do not want to spend $1K worth of upgrades/conversions on her so I was figuring a new front fork (here is where I start to need your help) but what else? what fork should i get (does the job, reliable, doesn't break the bank, etc)? should i do anything with the drive train (single chain ring and such up front?). for all the other components it still has pretty much everything it came with deore LX pretty much throughout (cranks, levers, shifters, derailers, etc.). i want to be able to do some bigger stuff with it so any and all suggestions are welcomed. but please keep cost in mind. for instance spending $800 on a front fork is out of the question. i would really like to spend under $800 for the total conversion and more or less around $500. thanks in advance for all of your suggestions and help.
