I may have read the name regarding road bikes but mine seems to be an all in one unit as well. Do you recognize which shifter the rear is? It just says STI but no other identifier. It looks like the rear are two separate units so I could just replace the brake lever to match the front and switch from cantilever to vbrakes. Vbrakes are newer technology I'm sure they would work better. I might even get a set with a front derailleur. Last time I checked front derailleurs were inexpensive. I just want to keep the cost down. Sorry about the large photos, I thought they would be downsized automatically.
