For disc retrofit: I bought a SRAM/Shimano disc/dynohub for $70, a disk kit for $70 (BB7) and a new fork for $60 (Dimension)
Still 3x the cost for a disc, they both weight within a few 10s of grams of each other overall.
Very true. I guess I should have mentioned that my "upgrade" involved a new bike.....
Sort of shoots the budget in the foot if the idea is to produce a cheap winter bike. Although I'm not sure those drum hubs are all that cheap either.....
