They are also a pain in the butt to get the preload correct. The FSA SLK carbon cranks are better than SRAM or Shimano in my opinion. One problem however is that the 30 mm axle gets in the way of the electronic wires if you're using an electronic group or the screw that holds on the under BB plastic wire guide if you're using manual shifting. It also makes it nearly impossible to use internal manual shift wiring though it is possible with great care.

Campy Record standard mount rim brakes work very well and can be set up to operate properly without moving. The older Campy dual axle brakes worked very well. The Dura Ace brakes I've used move about somewhat and you have to readjust them once in awhile to keep your brake levers from pulling the wheel over to one side.

Or at least not to that extent.

I find it very humorous reading about all the experts waxing and waning about Di2 when they have only been using it for a few years. And yipping and yapping about 11 or even 12 speed electronic components. Rookies. Little children. I've had Di2 since it originated. With 10 speed. I've used it twice as long as all the others. I was shifting Di2 when they were still suckling their momma's teats.

>>>>>> OK. I will admit it does not get a lot of use. 1000-2000 miles of riding per year. And it is relatively flat where I live so not too much shifting even when riding. But my point of rarely charging the battery does contradict the number one screaming complaint of those against electronic/battery groupsets. And that is the battery will die frequently. The battery does not die. The battery lasts for a long, long time. Anyone with enough brain power to shift a bicycle, will not run out of battery power during a bicycle ride. Worrying about a Di2 battery dying is comparable to someone fretting and fussing about the battery on their Timex digital watch dying.
>>>>> You can have reasons not to choose Di2, but battery life can’t be one of them. I can only think of one reason and that is cost. This is based on my experience with three Di2 equiped bikes. The oldest and most abused Di2 equipped bike is 8 years old.

That was a GREAT idea of retaining the large battery wired to the derailleurs. I haven't bothered to look into it but I suppose that they moved the intelligence into the battery so that it no longer needs the charging unit that was mounted either under the stem or in the end of the bar.

B17, Team Pro, Pro, Swift are the models. The Swift saddles have titanium rails. Lightweight. Google says it weighs 390 grams. Your Colnago C50 must be very light to be 14 ounces. Wow. No wonder Tommy can float up the hills and embarrass all the young racer boys with his speed. As for breaking in my leather saddles. No. They were completely comfortable the first time I put my weight upon them.

I've seen those but humans are dynamic, not static. Nothing
wrong with an approximation but those systems are not
definitive.

For me, Idéale are narrower across the center than Brooks
shapes and that difference mattered to me.
