I was thinking about this recently. Aren't many of the "inline" style levers folks around the forum use designed only as an additional brake to be used with road levers? A BMX style lever has the little ball on the end of the cable and pulling the lever pulls the actual ball/cable up. Many of the inline levers, while working, just kind of push the cable out as the lever is pulled away from the brake clamp.
I know it works, but just wondering if the inline levers should be replaced by a BMX style lever if one was interested in maximum efficiency/braking power.
