A couple of minor annoyances about the Project One process and ordering a frameset-only. There are hidden costs...
1) The disc frameset alone carries a $500 premium over, say, the $2999 Race Shop Limited rim-brake frame which is available off the shelf. This isn't really hidden, but it's a minor drag.
2) The integrated seatmast cap didn't have an integrated cost. It was an additional $130 despite not costing extra on complete Project One bikes.
3) Disc-brake frames with thru-axles should actually include thru-axles. $100 for DT Swiss front/rear thru-axles after looking at the accessory bag and not finding any. Why is this an important inclusion? Because thru-axle standards are still a bit varied. They have slightly different lengths and there are three different thread pitches (1mm, 1.5mm and 1.75mm.) There are also E-Thru and X-12/Syntace.
Try ordering a Madone frame set! "Oh, you want a bar/stem along with the frame? Better pay up!"
Any P1 paintjob is a minimum of $500 (MSRP) over the "off the shelf" frame (even for the "included" paint jobs). I wasn't sure about going with an "OTS" frame when I bought my Madone, but just changing the bar/stem would have incurred the fee. Luckily, I was able to use the standard bar/stem on my 9.2. What I tell everyone is that with Trek, you're better off buying a complete bike and selling the parts versus buying the frameset. You usually get a better price on the components this way.
