The Dia-Compe Tech 77 Locking Levers may be the most popular lever in BMX Freestyle ever. Used on many bikes back in the 80’s and 90’s the Tech 77 levers are still just as good as all the other levers out today. These aren’t always all that easy to come by so if you think you may need some for a retro build anytime soon I’d suggest you snatch them up.
