Description

The Izumi 1-1/8 BMX chain is 100% Japanese made. Still the best Track & BMX chains on the market

Features

Made in Japan. Izumi make these chains entirely in Japan, and they are a long standing pick for track and BMX riders.
1/2 x 1/8 inch. The standard single speed size, so it runs with BMX and track sprockets and cogs cut for 1/8 inch.
96 links as standard. Long enough for most set ups, so you break it back to whatever length your frame and gearing need.
100 links on one colour. The black chain with gold pins comes with 100 links instead of 96, so you have a little more to work with.
Suits track and BMX. The same chain covers a track bike or a BMX, so one chain works across both drivetrains.
