I had these custom made a number of years ago before twin top tube frames experienced a renewal of interest. These are the ones I have left over and time to make some room for other things.<\/p>\n\n\n\n
Full chromoly tubing, dropouts and gussets, a machined integrated head tube and mid sized bottom bracket. Cable guides allow the use of single or dual cables for the seat stay mounted 990 brakes. Head tube is also drilled for mounting the brake tabs. These are included with the frame, as are new bearings for the mid-bottom bottom bracket. Sorry, don’t have any headset bearings left\u2026<\/p>\n\n\n\n
These were built by one of the best bike welders in Australia and everyone comments on the quality of his work. Also then powder coated by one of the best in the business in Australia. Most old school people would know of them both!<\/p>\n\n\n\n
