Dia Compe's Tech 6 brake levers, also known as MX-128 levers, work great with any old-school style brake calipers such as MX-1000's, MX-900's, and a lot more.
The original Dia-Compe Tech 6 levers are still one of the BEST levers to use!
These levers features a "lock out" button that is easily pressed down to lock up your brakes, great for freestyle use. To release the lock, simply pull on the lever, and the spring mechanism releases the lock.
Just like they were made originally in the 80's.
