Hi Carl,

Apologies if you've answered this previously. I searched with no success.

What is included in the aero package option within the project one customization of the SC 7 series?

Is my Quarq Elsa compatible with the SC?

Scott

it's the non-UCI setup...fork, basebar, and speedfin.

quarq's compatibility page is here. the 2014 SC is BB90, so it appears the Elsa R will fit as long as you have the GXP version.

Hi Carl. I removed the front fork of my 2011 speed concept 9.0 and had a great deal of difficulty pulling the fork from the frame. The long rod just wouldn't pull loose without having to force the fork over a bulge in the front tube. Oops there goes the paint. As I did a bearing fell and I now don't know the correct location for it-- top or bottom of assembly? I've looked for a parts diagram for the assembly but can't find one. I do know that the rod extending upward from the fork is not going to just slide up into the tube. What's the best way to slide this back into place and where can I find a diagram or photos to show me how the parts are assembled?

Chris_Hanson and SummitAK nailed it in the other thread. Here's the service manual:

Carl, thanks for the always quick response. I used the 2011 service manual. It seemed simple enough, but the fork just would not slide out with "light pressure." The 2011 service manual does not show the position of the bearings. The updated service manual does but says that this is an area that has been changed from the 2011 model. I'm now not sure if I have both bearings nor their correct position. Can you describe the correct position of the top bearing? Can you point me toward a diagram that illustrates this?

the key is the lower bearing needs to come out at the same time as the fork...like the other two guys were telling you. same thing in reverse, when you put it back together, the lower bearing has to be installed on the fork before the fork slides into the frame. that part is detailed in the service manual.

here's a screenshot of the assembly. there are angled surfaces (45 degree chamfers) on the bearings, inside the headtube, and on the fork and on the preload nut which all need to mate up correctly. in other words, 45deg on 45deg. you'll notice that the upper and lower bearings only have the 45deg chamfers in certain places...in other words, the outside (and inside) of the bearing doesn't have 45deg chamfers top and bottom...they're only on one side. mate up the 45's. the zoomed-in detail of the lower bearing shows the outer 45deg chamfer (green) facing up, where it meets the same shape inside the headtube. there's a 45deg chamfer on the inside of the bearing which mates up to a 45deg surface on the fork (blue). upper bearing works similarly...only the outer 45deg is facing down into the frame and the inner 45 is facing up to mate with the preload nut.

if this doesn't make sense to you, or you're not comfortable with it, bring it to your Trek dealer.

Can anyone advise me if a 25mm tubular would fit into the old speed concept 9.5?

I managed to get a wheelset with FMB Paris-Roubaix tubies (which measure something like 27mm IRL) into my old 7-series (same frame geometry and tube shapes in the rear triangle)...mind you, it was a very tight fit and if that gravel grinder I was doing hadn't been bone dry I wouldn't have tried it. I also had to change my front brake from SRAM to Shimano due to clearance issues... but that was related to brake caliper design and that wouldn't apply to a 9-series. Long way to say: there's a good chance it'll work...but no guarantees. Some 23c and 25c tires have pretty tall profiles which has interfered with the draftbox for some riders as well, so you have that to consider if you run that accessory.

Carl,

I during the offseason, I would like to make two changes to my 2014 SC 7. Add power for sure and possibly DI2 components.

Keeping in mind that I have the Bontrager bike computer with the integrated sensors, what power meter would you suggest? What DI2 components would you suggest?

Thank you

I would suggest you get the powermeter and Di2 hardware that suit your needs and your budget. I have no idea what combination makes the most sense for you...quarq and ultegra Di2, powertap and DA Di2, who knows. Di2 doesn't care what powermeter you run, and vice versa...they don't really interface with each other electronically. Likewise, Di2 doesn't interface with your computer...but the powermeter might, depending on what computer you have and what powermeter you buy and what "language" each one speaks (e.g. ANT+).
