Carl, et. al., I posted this in its own thread, but since there is a lot of fit discussion here and I'm hoping to get some help, maybe I'll get lucky here. I'm trying to become a Speed Concept owner, but don't know what size to become the owner of. Thanks to anybody who can be of help. Here is what I wrote in the other thread:
I'm trying to figure out which size Speed Concept 7 would be best for me. I read through Trek's Speed Concept fit and sizing guide, but most of is about the Speed Concept 9 because of its unique front end. (By the way, there is not a shop around here with a good tri fitter, but I am very comfortable with my current position, which I have tweaked during years of trial and error and lots of reading on Slowtwitch, measuring, and videotaping.) I know that the SC 7 is more flexible fit-wise because you can just stick a different length/rise stem on it, but I'm between a medium (54 cm) and a large (56 cm) and was hoping maybe Carl or others with experience could help me out.
Here are the numbers from my current setup, measured as shown in Trek's Speed Concept fit pdf .
My current frame is a 54 cm Cervelo Eyre Tri (650c), with lots of seatpost and a few headset spacers (it was a long and low frame and I'm pretty long-legged for my height).
Just the frame's measurements are:
Frame Stack: 480mm
Frame Reach: 440mm
And here are the measurements to the contact points, which is what should really matter here:
Elbow Pad Stack: 624mm
Elbow Pad Reach: 472.5mm
Reach to front of base bar: 668mm
Base Bar Stack: 524mm - 564mm (since the base bar isn't flat, those are the numbers to the flat part of it and to the end where the brakes insert)
Saddle Height (from center of BB): 776mm
Saddle Setback: 5mm
Any help would be very appreciated.
If those numbers don't get me anywhere, does somebody have the stock elbow pad stack and reach numbers for the 7 series? I know this is tough because stems change everything, but if I could see what comes stock on it (what the stem length and rise is, and what Elbow Pad Stack and Reach that creates, I could do some math.
