Vintage SOMA
Competition
Road Frameset with Tange No. 2 Double Butted Tubing
Up for sale is a nice late 1970’s vintage SOMA
Competition
road frame set.
Handcrafted by Kawahara with Tange No. 2 double butted chrome-moly seamless tubes and SunTour
GT-IV
forged horizontal dropouts.
(Tange No. 2, also called Champion No. 2, later simply called No. 2, compared favorably with Columbus SL tube sets as both shared the identical .9/.6/.9mm butting. With Tange’s quality control and finish arguable being a little better)
. Tange chrome-moly fork with chromed tips and forged dropouts. Headset and bottom bracket have been cleaned and greased – ready for years of service. Sale includes SR LaPrade micro adjusting alloy seat post and recessed binder bolt.
The frame is in excellent structural condition. Cosmetically the original paint and graphics are in good condition. Pretty even coverage of marks and scuffs from normal use,
(far too many to try to list individually),
please see pictures. Over-all I’d rate the condition about an 8 out of 10.
