I did a little computer work for one of my computer clients who owns a bike shop. In exchange he gave me a pair of Shimano mechanical disc brake calipers which I know won't work very well with my Ultegra 9 speed shifters.
This conversion is for my Motobacon Fantom Cross Team Ti that has disc brake tabs. I'm doing this as a budget build. I so far have 44 dollars into the rims (Mavic A119 32 hole touring rims, I'm a big guy and wanted strong rims), 25 dollars for new spokes, and that is it for now. All the rest of the parts (disc brake hubs, discs, etc) are all stuff I had in my stock of spare parts. And my time for the calipers.
Now I know that the Ultegra shifters won't work well with the mountain disc calipers but I have a pair of V-brake travel agent adapters at my disposal. Do you think it would be possible to use the travel agents (not the inline models but the noodle replacement models) to allow the cable pull to be correct for the mtn disc calipers?
