Brake Lever Return Springs or No
Campy Ergo levers have no return spring in the lever and Shimano
levers are sprung. Would using a Shimano or other sprung lever with Campy brake arches make any difference in actual brake function or feel of the brakes? My preference is to have very solid feeling brakes. Right now, I'm using Cane Creek SRC 5 brake levers with DA 7403 brakes and I want to sell those and switch to Campy Chorus, front and rear, dual pivot brakes. The 7403s look and work great but they are worth more to others than I. The preference for Campy in this case is subjective only. |

If you keep your cables and housing clean and friction-free, you should have nothing to worry about. If anything, having an unsprung lever will increase your ease of braking. I keep my MTB caliper spring tension just to the point where the brakes will fully retract, and this allows fine-tuned modulation. Beginner riders will want to feel smooth, yet firm-to-pull brake levers on a new bike because they "feel" stronger when in fact they are directly reversing the forces they really want. -- Phil, Squid-in-Training |

It will make the lever pull a wee bit harder but a very small amount. Using sprung levers with Campag calipers will work fine.

The brake lever presses on the shift lever, and the shift lever's spring acts as the return spring for the brake lever. James Thomson |

I've used an old Weinmann non-sprung lever with a 105 dual-pivot and it felt, if anything, nicer than with a 105 lever. This was just a front brake, however - a rear brake with full-length housing might cause sufficient friction to stick. |

James Thomson All correct but that spring, altho it may have a small affect on brake lever pull force, is really to ensure the shift lever is 'out' after braking. |

They may make the brakes feel more 'solid' to some people, but I find this reminiscent of putting a weaker return spring on a car's gas pedal then believing the car is more powerful. If the cable friction is too much for the caliper return spring to overcome, something is wrong. Address the problem, don't cover it up with a spring at the lever. The only reason I can see for the springs to exist is to give braking some immunity from shifter activity when both functions are combined in the same lever. I get complete immunity by doing my gear shifting at the downtube instead. -Luns |
