A more modern alternative to the Dia Compe MX 122 levers, also available at Track Supermarket. Sold as a pair. These are an original design by Testach of Tokyo, Japan. I have actually seen these fitted to Nagasawa Team road racing bikes, as well as keirin pro rider's road training bikes. Available in 24mm and 31.8 diameter type as well as silver or black finish. I used one of these levers on my De Rosa track bike for a while, and really loved it. It has a nice light feel and is spring loaded, unlike the Dia Compe levers.
