Built in Japan by Kuwahara, and imported to the UK by Evian in London, Hirame were available throughout the 70s and early 80s and offered a range of high quality frames at a great value for money price. Japan was the best mass producer of bikes through the 1970s and Kuwahara produced a huge number of well built bikes for various brands and markets. Hirame frames are generally built with Ishiwata tubing and neat cast lugs, the number of braze-ons usually indicates how high up the range the bike sits.
The Osaka Pro was the top of the range frameset offered by Hirame in the early 1980s. Built from double butted Ishiwata 022 'Speed Gallant' tubing with Shimano dropouts and a neat one piece fork, the Osaka Pro was a Japanese built race frame at an affordable price. With its metallic gold paint and chromed rear end and fork it makes for a very striking bike.
If you're taking part in L'Eroica or any other vintage event, this frame is of the correct age, so you won't be disqualified for being a rule breaker!
The frame's been carefully checked by one of our mechanics to confirm the alignment's correct and there's no damage to the threads. If there are any minor issues worth noting we will do so in the overview section below. Please take a good look at the detailed photos so you can see the cosmetic condition of the frame before you buy.
