WORLD FIXED GEAR CULTURE
WE NEVER
COASTED
The heat never went away. It moved cities.
Tokyo, Seoul, New York, Barcelona. Track bikes are still being built, ridden and argued about. This is where the scene and the parts on those bikes are written down.
FIG. 01 — TRACK BIKETAP A PART
Track bikes run old standards and current ones side by side: 1 inch and 1-1/8, JIS and ISO, 1/8 and 3/32. This site holds the standards themselves as data and derives compatibility from them, instead of maintaining a table of every part against every other part.
When we have no record for a combination we return ❓ UNKNOWN. We do not guess and call it a yes.
