Finally, a chain tensioner that meets the stringent NJS standards! For any product to be used in Professional Keirin racing in Japan it has to be "NJS" certified.

This compact chain tensioner may be small but it is top quality. Do to the ingenious use of a double-threaded screw, it adjusts from 1cm in reach all the way up to 3cm. New design uses a 3mm Allen wrench! Fits drop-outs up to 5mm thick. Although designed for Racing, the ease of use makes this perfect for fixed gear road bikes. Sold in pairs. Made in Japan by Mikashima ( MKS).

Don't settle for those ugly BMX-type adjusters... get MKS!
