That is sacrilege of the highest order only Campagnolo SR may grace that frame. Beg, Borrow, Steel On a serious note. I have been riding Ultegra DI2 for that last 18 months with no issues, the stuff is bomb proof. The on the fly adjust-ability is great and a big plus for me. The only thing to watch out for is if you leave the bike standing for a long period (a month or two) the computer seems to calculate remaining battery level on that rate of use, so you might get caught out on your next ride where it will drop in to small ring and you will only be able to use the rear derailleur. In reply to the guy's who have had it not working and stuffing up there race. If they are sponsored Pro's then I'm not surprised as a large number of them treat there equipment like $h!t as they not paying for it. I have seen It first hand and been the one that has to fix it. It also doesn't help when someone manages to crash in every race and bring down half the bunch. (This might not be the case). On "SwissVan's" point make sure it is wired correctly and nothing is rubbing, catching, pulling, etc. The key is doing the job right the first time. As for the washing. I would happily ride mine under water. First ride out the box 80km from home I got caught in one mother of a thunder storm and the "rain" if I can call it that was bucketing down from all directions. After that ride with no problems I was sold. Now when washing I use the hosepipe on full blast and have never had the slightest issue. every few months I do however out some grease on the battery terminals and it's good to go.
