They are both second level group sets from their corresponding manufacturers. That Campy do not use such a steep drop in construction techniques doesn't change that. By me having and using both Chorus and Ultegra. Today Chorus is third level btw, you have to pay attention Tom. You have Super Record, Record, Chorus and then Potenza. Centaur is also still around, on par or a little below Potenza. Super Record is a 12 speed group. Ultegra and Chorus are 11. On the Ultegra you have the ability to shift large cogs which is missing on the Chorus though I suppose that you could do that by using a Potenza rear derailleur, I'm not sure that it uses the same shift ratios. Chorus is 12 speed and the currently most popular setup is 11~34 with a 32x48 carbon Hirth crank (no pinch bolts). You may prefer Ultegra, and it's a fine set, but it's not 'equivalent' to Chorus in my opinion. Well, I haven't seen any record or chorus that would take a cog larger than 28 tooth though they've strained them to 29. But you're working with the 11 and 12 stuff and although I was told that the 11 had the same limits as the 10 perhaps Campy has finally gotten the message. But there's NO WAY that a pro could ride a 48 large ring since they're spinning out the 50-11's. I spin out a 50-11 with a tailwind. To complement another current RBT thread, Campagnolo offers various gearing options: https://www.campagnolo.com/US/en/Com...set_12x2_speed which is an inherently good thing, given humans as we are. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 Trying to find something on that Campy site it looks to me like the EPS is only on a Super Record Group. I was looking through eBay at Di2 groups and there are a LOT of scratched up groups. I don't know if this is from racing or from just normal riding and falling. I also don't understand the DuraAce wiring kit I got that has 4 or 5 connectors per wire. uite frankly I can't see the slightest reason for that since the computer is in the stem unit and that should do any and all updates. I suppose that they could put all sorts of feedback loops but I can't quite see how that would improve anything. The SRAM stuff has to be pretty power intensive with radio links because you have to have enough RF power to override any local electro-magnetic disturbances. Imagine riding next to the BART tracks and having the local power generator kick in because a train is about to enter that power sector. |
