Binder Bolt

BINDER BOLT:
GP seat post binder bolt - titanium alloy - 8 mm diameter - 5 mm Allen key release ... [A somewhat unusual bit of French kit dating from the mid to late 1970’s, and one which therefore, would be contemporary to the original build date of this Graftek frameset. The seat post binder bolt supplied with a Graftek G-1 sold as a "complete" bicycle would have typically been a chrome plated Campagnolo model 1072.]
