Electronic shifting system
Campagnolo had a prototype of it's electronic shifting system. The
problem however is that they have chosen to use the solenoid as the primary driving mechanism. The same goes for Shimano as well. Mavic's Mektronic used the dérailleur pulley to drive a worm gear thus saving weight. Both Shimano and Campagnlo's shifting system requires a very large battery. The really big issue is if these shifting systems will withstand a immersion test. This requirement seems a bit extreme, but there are occasions when I am riding and you have go through a very deep puddle with no other way to go around. |

All it takes is a strong jolt and the clutches lift and the bike shifts somewhere on it's own. The other methods probably use stepping motors with leadscrews to give very precise and reliable position sensitive shifting. The problem is that they use quite a bit of power. I'm still trying to figure out what the advantages are to electric shifting. Anyone got any suggestions? True that if you have electronic shifting you can shift even if you're a weak kneed shifty eyed moron - say like Kyle, Howard, Carmine or datakoll. But for anyone with the coordination of a skunk sprayed squirrel Ergo or STI has no drawbacks aside from those huge lever bases. |

I can't wait to write a virus for the self-adjusting software. |

The only problem I heard of was the radio frequency interference problem on rare occasions One complaint had was that the solenoid was not replaceable.

Like I asked a shimano clone at Interbike, pointing to a particularly goofy FD setup, "what's that for?", I ask.."For selling" he answers. Like disc brakes on road bikes, tubeless, threadless, compact frames, oversized handlebars, etc....many will say what an improvement these things all are but mostly they are for 'selling'. |
