It finally took one of our 'crazier' customers, Taru-kun, to envision it as a daily ride! Many customers admired it, but being a funny bike, with a very agressive 700c rear, 24'' front arrangement, most people passed it off as more of a piece of artwork, or even a novelty, than a usable frame. But the staff here at Giracha, can be pretty persuasive....:) Front and rear disks on the street? No problem! Tubulars on a daily? Yeah...!
The Nitto slider stem has a nice long quill, and is adjustable for fore and aft positioning, so is perfect for a frame with such funky geometry....and the odd looks of the stem go well with the front disk, and funny frame shape.
Although I cannot recommend riding no-hands with a front disk, wind really is not as much of an issue as many people might think. And in Japan, where the roads are nice and clean, tubulars are also quite sensible. Due to strict laws in Japan, dual brakes was a must-have, but a bike this crazy needs some unique brakes, too. Tempra, in Tokyo, have been making CNC'd and laser cut parts for track bikes for several years now, and specialise in parts which make fitting brakes to track frames easier. Since this frame has no holes drilled for brakes, we used Tempra's brake adapter plates front and rear. For the brake lever, an MX-122 from Dia Compe, which has a 'shorty' lever: a CNC'd piece made as a collaboration between Dreamworks Tokyo (one of our favorite bike shops) and Osaka's own Dia Compe! The very rare, and odd 'AX' series Dura Ace calipers were sourced in NOS condition, and were bolted to the Tempra plates. The pads are Dia Compe carbon rim pads, cut down to fit the old AX calipers.
The Suntour cranks were an obvious choice. The anodize coating was removed and the cranks were polished, along with the 'nagasawa' pantographed chainring. These are very rare, because Mr. Yoshiaki Nagasawa does all of his own pantographing! Since Mr Nagasawa was quite heavily involved in Suntour's parts developement, and also in the design and production of these Suntour team bikes, the chainring and saddle seemed somewhat fitting. Actually Nagasawa Racing, and Panasonic/National are very close to each other in the Osaka/Nara region of Japan. The two brands are very close, and often seek advice and cooperation from one another.
With the idea of riding a funny bike, as a daily, in mind, Taru-kun just kned it has to be 'disk,disk'! Here at Giracha, we like this way of thinking, so we were quick to hook up a rare 24'' Araya carbon disk for the front, and although an Araya rear would have been nice, for the time being, we fitted an in-stock Zipp on the rear. We will fit an Araya when one becomes available for the right price! This was a very fun bike to build up, and yes, it is actually being used daily.
