GOKISO Korea

GOKISO is a bicycle component brand launched in January 2010 by Kondo Machine, an ultra-precision machine tool and metal cutting company in Aichi, Japan. Founded in 1947, Kondo Machine makes jet engine bearings and ultra-precision dies, and its factory is certified to the JIS Q 9100 aerospace quality standard. GOKISO hubs and rims are machined in that same factory, to the same standard as aircraft parts.

The name comes from Gokiso Hachiman Shrine in the Gokiso district of Nagoya, the neighbourhood where the company began. Instead of following trends, GOKISO set out to keep design, machining and quality control entirely in its own hands and put "truly good things" into the world. That is where the brand starts.

The Super Climber is GOKISO's flagship hub. Body and axle are both machined whole from aerospace titanium alloy Ti-6Al-4V, and sixteen finger-like elastic elements cut around the outside of the body absorb road shock and pedaling torque. The complex, fin-like shape no other brand can replicate is not decoration. It is structure.

The goal is to stay light and rigid without losing suppleness in road racing on high-pressure tires and stiff carbon rims. It is made as a QR rim brake hub, a 12mm through axle disc hub, and in dedicated Moulton and Brompton sizes.

The Climber carries the Super Climber's elastic outer body design over to an extra super duralumin A7075-T73 body. The axle is still titanium Ti-6Al-4V. Fingers on both sides of the body link flange and bearing housing, and the rear body is partly thin-walled so it stays stiff under pedaling torque yet soft against impacts.

The rim brake S-spec weighs 202g front and 401g rear. The through axle disc version is built for flat mount disc road and gravel in 12 x 100 / 142mm, with Campagnolo, Shimano or SRAM XDR freehubs. Matte red and matte black are standard; small-batch colors such as brown, light grey and purple arrive from time to time.

GOKISO has made dedicated small wheel hubs from the start. Sizes no road hub can fit, such as the Moulton's 71mm front and the Brompton's 74mm front and 112mm rear, are produced in both Super Climber and Climber grades. For the disc-braked Birdy there is a QR disc hub.

A small wheel turns faster at the same speed and picks up more road buzz. It is where GOKISO's structure, isolating the bearings from external stress, is felt most clearly. As the official Moulton importer, Rubi Workshop keeps Moulton-specific GOKISO hubs in stock and builds the wheels too.

SLP is GOKISO's full carbon clincher rim. Carbon fiber is machine-wound onto a mandrel in unbroken layers, with extra carbon laid only around the spoke holes where loads concentrate. Rigid where it must be, light everywhere else. The 30mm wide profile supports the tire broadly to cut both rolling and aerodynamic resistance, and the logo reflects light at night.

Rubi Workshop stocks complete wheels pairing the 30 x 45mm disc rim with Climber or Super Climber through axle disc hubs. 24 holes front and rear, Sapim CX-Ray spokes. UCI certified and made in Japan.
