Hi Terry from Virginia here. Just posted in the "Welcome" forum and noted that I should ask questions in the proper forum. Well, actually I noticed it a little late and had to edit that one and bring my questions here! I am ordering a Micargi Pantera 7speed with cantelever brakes for my first build. I want to put a SBP shifter ont the bike.Does anyone know what the seat tube and front tube (downtube?) diamiters are on this bike? Bike buyers were kind enough to check using a ruler and sighting in but I'd feel better if some one had checked with a caliper before I go ordering shift kit that may be the wrong size. Guess I can check myself when the bike gets here but I wanted to have everything together about the same time so I can get started. I was also considering a springer front fork but having a hard time finding one with cantelever mounts. Pirate Cycles has one but it's not in stock at this time. Thanks Terry.
