starting to get back in the swing of things after a 5 week vacation in Berlin and Italy. here are some pictures of the finished front triangle of Logan's 650b touring bike. The s&s couplers were installed by Bilenky cycles in Philadelphia and the tubes were waiting for me when i got back from my trip. with the couplers already installed in the tubes, building the frame is the same as if the couplers were not there.
the lugs are Long Shen arrowhead design, the crests or "bat wings" are a nice aesthetic. they do make modifying the lug angles much more difficult. on this frame i decided to fillet braze the bottom bracket. this bottom bracket is designed with sockets for the chainstays. fillet brazing the bottom bracket allows for a broader range of frame geometries than a lugged shell will allow.
this frame is designed for loaded touring, so it incorporates an relatively low trail front end, 55mm fork rake, 73 degree seat tube and headtube angles. it will be able to accommodate a lowrider front rack.
