Campagnolo Electronic
Anyone know the latest on this?
Last I heard was from early spring where Campy was doing some on-road development. Have they hit some snags? I had understood they were to release this kit this year, but now looks to be delayed. |

I had understood they were to release this kit this year, but now looks to be delayed. A possible snag being that it will be hideously expensive and offer no real functional benefits. A message to component makers: bicycle drivetrains with a bunch of exposed front and rear cogs (with electronic shifting or otherwise) is a dead-end. Derailleur-based gearing systems are fragile, attract dirt, wear out rapidly (especially chains) and are complex to set-up and then maintain the indexing. You would think we would have made progress beyond the great Sturmey-Archer 3-speed hub of the 1930's. If someone develops an efficient internally geared rear hub with about 10-15 gear choices, and it comes within 200 grams of a derailleur drivetrain, then I'll be impressed. And then I will buy. |

Especially in the section of the market where Campagnolo is this is definitely not true. High-quality derailer systems are not too fragile, or at least I'm not seeing many broken derailers, chains or cogs. I'm sure for example downhill mountain biking is different, but they still use predominantly derailer gearing. I get between 3000 to 5000 miles from a chain on a Campagnolo drivetrain before excessive wear, and most people would not consider that rapid. I always found setting up pretty easy and it requires basically no maintenance. In fact the only adjustment you CAN do after the initial (correct) setup is fine adjusting the cable length, but good cables don't stretch much. If someone develops an efficient internally geared rear hub with about 10-15 gear choices, and it comes within 200 grams of a derailleur drivetrain, then I'll be impressed. And then I will buy. The 14-speed Rohloff hub is within 200 grams of many derailleur drivetrains, and in any case the weight difference is so small that it doesn't make any difference. It's also efficient enough for most uses and is indeed an impressive piece of equipment. What are you waiting for? -as |

It's also efficient enough for most uses and is indeed an impressive piece of equipment. What are you waiting for? Knowing Dave, a thriving market on eBay . More seriously, Rohloff hub drives compare well with new complete high-end derailer drivetrains, but at a notable weight penalty and a certain efficiency penalty. More worryingly, there's basically no used-Rohloff market, while used or OEM-surplus derailer drivetrains are available very cheaply, which is nice. Since a new Rohloff hub alone would cost substantially more than the entire price of my carefully-crafted (and race-winning) race bike, it is a very hard sell. I think the real deal, long term, will probably be the Shimano Nexus 8, which has a reasonable range of gears and reasonable performance for less than one third the price of a Rohloff. The old 7-speed version is slightly cheaper again. for the US$250 the primo hub (plus shifter) would set you back, I could make a pretty nifty US$300 super-commuter: take a road frame with horizontal dropouts, add Nexus 8 and chainguard, budget for fenders and a front dual-pivot brake with good pads. Yes, I can probably find an appropriate base bike for $10. Little maintenance, not too much money, fairly light, and way cool. http://sheldonbrown.com/harris/rohloff.html http://sheldonbrown.com/harris/shimano-nexus.html The SRAM Spectro 7 is also nice, but a bit more than a Nexus 7 and a bit less than a Nexus 8: http://sheldonbrown.com/harris/sram.html That said, this putative super-commuter is competing with the near-free lightly-used old road bikes that are thick on the ground most places. You have to really like cleanliness, low maintenance, and unfussy shifting to pay the premium for a hub-shifting bike.

I have a modern Campagnolo drivetrain on both of my bikes and I don't think there can be any real improvement on the way it works. I'm not sure what you mean by sequential shifting, but Campagnolo levers already allow changing multiple gears with a single press of the lever of the button. The only concrete improvement I can think of is automatic fine adjustment of the front derailer when you change to a different cog in the rear. I'd be willing to pay $20 for this, but not the $2000 that the electronic drivetrain is likely going to cost. Actually I do agree that derailer shifting is a dead-end in the sense that there's not much that can be done to make it any better. But that doesn't mean it's not going to remain the best choice for many applications.

More below. I would agree that internal gear hubs don't have the market share they probably deserve. Most bikes with cheap derailer drivetrains would be better off with a decent internal gear hub. -as |

Didn't Mavic also experiment with electronic derailleurs? I remember the bikes
on the neutral service cars, during the (now defunct) Trans Canada Tour back in 1999, had Mavic electronic derailleurs on them. J. Spaceman -- My email address ) is fake. Email sent to it will only get caught in my spam tarpit. |

Thanks for the comments all --- I guess nobody out there knows the
status either. OK - I'll get drawn in by the trollers ----- on the chain wear comment -- I'm sorry, but 5000 miles on a chain is poor. I am assuming road riding - I can understand off-road would shorten a chain's lifespan. I get ~15,000 miles from my chains. If I get 10,000 or less, I'm disappointed. I'll tell you my secret, and its not a secret at all -- chainwax. I wax my chain about every 500mi, and with the powerlink chains now, it's easier than ever. I make a homebrew, as it has been over 5 years since I could find it in any stores. But, paraffin + PTFE powder + a tiny bit of slick50 does very well. I log every ride, every bit of maintenance, so I have 20 years of data. Anyway - you should be able to get well over 10,000 miles from a chain on a road bike. Now, electronic shifting - I was just curious on their progress, that's all. I understand your point of view in that it wouldn't seem to offer any advantages. But, I'm into product development, and besides -- I HATE all those cables sprouting from everywhere on those bars these days. I still use downtube shifters, which perform much better, and leaves me a very clean cockpit. In my opinion, the current multi-use brake levers were a step backwards -- much the same way you see the electronic shifting development. I feel the early 90's were the cleanest so far, and maybe the new development will go back to that clean package. So, we all have different points of view. And, yes, Mavic did make 2 versions of an electronic system - the ZAP 8-speed that came out in the mid-90's, and the Mektronic 9-speed that came out maybe 5 years later. I've got both, and love them. I have the ZAP on my Lotus TT bike -- of course, gotta keep it original to the Boardman build!!!! I even crashed on it once -- smashed the cover on the derailleur, but it still worked!!! and it got me home to my road rash kit just fine!!!! Anyway, I've since stocked up on my ZAP parts and should be good for life now. The wireless development in the Mektronic opened up another whole area for various products. I will say the huge rear mech is something I still struggle with. I love the ZAP rear - much nicer package. But, the wireless and de-centralized power storage is an advantage for the Mektronic. Anyway, I had heard bits & pieces about the Campy, and how they were doing a powered front as well, so I continue to be curious about design cues, packaging, kinematics, execution, etc. etc. Anyway - flame away!!!! And get some chainwax!!!! |

I had understood they were to release this kit this year, but now looks to be delayed. Seems to be working in the prototype stage. One 'snag' was the high power requirements of the front der. It is kinda keen as the front der moves on it's own when the chain goes to larger cogs, automatically keeping the chain from rubbing, and is electronic when whifting between rings. Gonna be VERY pricey if they make it, which is still a question. May see it in Milano in the September bicycle show. |

Thanks Peter -- will be watching for news. I was curious about the
front der as well, and how they're doing the rear movement. Mavic's method for moving the rear was/is very unique.

There is no projected date of release. There was a writeup on Cyclingnews around the time of Paris-Roubaix because somebody or other rode the drivetrain there. That may be the highest profile test so far, so it also may be why it seems like it's on the verge of retail. -eric |
