David’s Bicycle

David's Bicycle

David waited patiently for his bicycle for nearly two years. This was my first frame with post-mount disc brakes, and a lot of work went into making the mounts blend in with the Shimano dropouts and fork ends

To accommodate David’s physical strength and ride preferences, the frame is made with heavy-gauge Tange tubing and features heavy-duty BMX chain stays, which combine to give David the comfortable ride he sought, without the feeling of riding a soggy noodle. The frame features a full set of braze-ons; internally routed rear brake cable for the mechanical disc brakes; internally routed dérailleur cables; post-mount disc brakes; and, clearance for 38mm 700c tires without fenders (32mm with fenders). Paint (Imron #1021, Orange with a pearlescent overlay) is by Chris Kvale.

David liked his bicycle so much, he acquired a track bicycle I built, modified for everyday road use when one gear is enough.
