Do the return springs in aero brake handles serve any significant function? (I have never seen non-aero brake handles with return springs.) With my single-pivot sidepull calipers, I need all the braking help I can get, even with KoolStop pads. I removed the springs from my Peugeot (DiaCompe aero handles, single-pivot Galli sidepulls) and now enjoy slightly better brake response.

I have also removed them. As long as the springs in the calipers return the levers to position,no issues.

They should help the brake lever to fall back in rest mode, and the brake to open up.

Even when set up at maximum force, the spring in V-brakes and in many cantilever brakes isn't very strong. So if there is too much friction in the cables, the brake won't open quickly or might even drag a bit on the wheel.

By comparison, old-style centrepull brakes and many old-style sidepull brakes had very powerful springs that have no problem in opening back by themselves.


In other words, if it works fine without springs, you're ok. But for those who would be tempted to remove the springs, try it only if you feel your brakes open up very quickly, and don't throw away the springs until you are sure you don't need them.
