MKS Track Bike Chain Tensioners (Aluminum Frames)

New, wider model now fits thicker dropouts!

Have you wanted a good quality tensioner but couldn't run the MKS one because it wouldn't fit your Aluminum frame? They've heard your complaints.

This compact chain tensioner may be small but it is top quality. Do to the ingenius use of a double-threaded screw, it adjusts from 1cm in reach all the way up to 3cm. New design uses a 10mm wrench - or use your fingers! Fits drop-outs up to 8mm thick - like those on most Aluminum frames. 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!

This model is not NJS certified due to fact that aluminum frames are not NJS certified. However, the quality is just as good as the NJS model.
