I've been out of MTBs for more years than I want to admit but I'm trying to make the time to get back into it. Right now I'm just logging road miles to get back into shape.
Here's the question. I've got a Cannondale SuperVactive that I built up with XTR components back when I was racing. I think it is from the 2nd yr they built the frame (possibly the first). In any case I'd love to find a way to retrofit disks. I'm 6'4" and at my best race weight I still tipped the scales at 197 and I'm 20 pounds away from that now so stopping always been and will be an issue.
I know that I can change out the fork and get a front fork that will accept disks. C-dale made that option available a long time ago, but is there anything that I can build up to put a disk on the back?
You could weld on tabs but since most of your braking power comes from your front I think you would be easier to just replace run a front disc. Replace the fork and get a 7 inch front rotor. That should be enough stopping power unless you are doing some sort of gravity riding.
I'm not a gravity driver, but I have been known to do rides that do have long steep descents. I've blown more than one rear tube (light wt silicon variety) from heating up the rear rim. I know, probably not using the best technique>
