With compact frames, manufacturers often use "effective top tube" and "effective seat tube" for their measurements...basically what the heights and lengths would be *IF* the frame were of "standard" geometry. The slope of the top tube determines how different the actual versus effective distances are. For instance, my Interloc's top tube is almost level but has a very small slope...the actual TT length is 61cm, the effective TT length is 61.2. My ParkPre has compact geometry...the actual TT length is 56cm, the effective TT length is 58.5cm.

Says 52cm, and my Roubaix Pro says 54cm on a sticker on the seat tube. I can't find how Fuji measures their frames so I don't know what the measurement is; I'm guessing center-to-top seat tube?
Sorry for sort of derailing the thread but I figure this info is pertinent to BD sizing as well, for other newbies like me.
EDIT: didn't see urbanknight's reply until just now. I was afraid this was the case. OH WELL

I just realized that Trek geometries are hard to find. I was going to say compare the top tube and seat tube angle from the Trek and compare them to the charts for the bikes you're considering, but that might be a challenge with Trek.

Just to give you a heads up on the dawes sizing. Im 5'4" 29" inseam. I currently ride a motobecane vent noir 50cm that fits me perfectly. I can give you my other measurements when I get home to give you an idea of my fit. Now my friend has a Dawes Lightning 1200 size small 46cm. Now the reach on that bike is slightly too long for me and with the seatpost all the way down its too high for me. Id have to put a shorter seatpost in order for my legs to be at the optimal position. Of course I couldve changed the seatpost and used a different stem, but the point is if I were to get that bike I would've sized down and gotten the smallest one. I do clear the standover, but the rest of it is off.
and thats my 2cents.
Just watch videos and read the parktool site for adjustments. Its not that difficult. My vent noir shifts perfectly even the triple. I even did the adjustment of my friends Dawes that that works perfectly fine too.

Im saying that the 46/small wouldve been too big for me. I dont know the actual geo of the bike since its not listed. If I were to get that bike with my measurements I wouldve gone with the 44/xsmall. Not that I couldnt have adjusted the fit of the small with a different stem and seatpost.

Bought 2 bikes from them, they're a stand-up, reputable business. Bikes came in 5 days, in great shape. If you're experienced with wrenching, NP; otherwise take it to your LBS after you assemble it. This assumes you know your proper size. One caveat: avoid Sora shifters with a triple chainring, the downshifts can break your frickin' thumb. The rear shifters are fine. Upgrade to a carbon fork, your hands and wrists will be much better off. Good luck!

Find the model you want, go to the "Fit and Sizing" tab below the picture of the bike, presto.
