Gary’s Bicycle

ginobob

The latest (2016) Domínguez cycle to leave the workshop: A 650b randonneuring bicycle named “Ginobob” by its owner, Gary.

The frame features a full set of braze-ons; internally routed rear brake cable; internally routed dérailleur cables; post-mount disc brakes; internally routed headlight wiring; and, clearance for 42mm 650b tires. Erik Noren welded the steel plate onto the drive-side chain stay for chainring clearance. Paint (Imron #32678, Dark Red) is by Chris Kvale.
