Looks like the new Madone's have a proprietary headset and BB bearings? Or am i misinterpreting the article? How will this work with different model cranksets?
I had kind of a bad experience with the proprietary headset i had on my 5900.
How does the seatpost work, that is how much adjustment do you get. And i guess that is proprietary too?
"...Designed to accept most two-piece crank designs from Shimano®, Bontrager®, SRAM®, FSA®, and Campagnolo® without affecting the q-factor, the integrated bottom bracket design saves 40 grams compared to traditional designs..."
"...A slip fit bearing system that uses common, standard-sized bearings and requires no specialty tools or big torque loads..."
So it does look like a proprietary BB bearing system that will work on "most" two-piece cranks.
Edit. Per Damon Rinard at Trek: "...the bottom bracket bearings are a standard size, so you could easily change them to ceramic aftermarket ones if you wish..." http://trekroad.typepad.com/trekroad....html#comments
