    I like bikes that are very nimble.

    If I am 5'10 is a 22.5 toptube to small?

    What do you base you decision on? Is there any kind of rule of thumb?

    I think it depends on the seat tube angle, I've had several bikes with that TT and I'm 5'-11". The thing I hate is having a bike that is so short in the TT that you hit your knees when sprinting

    depends on personal preference, the athertons used to ride xs size giant bikes. it worked for them.

    Just go to a bike shop and test ride a few bikes in different sizes. Then you will know what geometry you like. Don't rely on anything you read to base your decision on.

    Here is my take -

    I bought the FOES this past season.

    I hated it. So I changed the way I ride just to fit the bike. I made myself comfortable on it but running way more sag (2 1/2) instead of 1 inch.

    This dropped the bottom bracket to 12 3/4 sagged.

    The measurements on the FOES TT is 21 to the bottom of the seatpost.

    I know the basic geo I want but not sure about the TT length. I would like to get on the front of the bike when turning instead of hanging off the back of the bike. A longer top tube would force that. So I think I will get the large which is a 23.6 TT.

    Keep in mind that the measurement 'c' on that pic above (Scott I think) is VERY different than the way you describe measuring your Foes. Effective top tube != top tube measurement. Unfortunately, not all mfg tell you exactly how they are measuring this.

    I measured my TT on the FOES just like the Scott up top.

    Center of headtube to top of the end seatpost which was 22'. (I put a level on up of the headtube to be sure it was a straight angle just like how Scott measured theirs above)

    The angle of the seat posts are much different though.

    56 degrees (FOES) VS. 74 degrees (SCOTT)

    That tells me the Scott is just a tad longer then the FOES because the seat post on the Scott steeper.

    Right on, just sounded like you were comparing different measurements due to this:

    BB to center headtube (horisontal) is often more intersting to actually get the real cockpit lenght of a bike. However, that information is often not given. But, headtubeangle, wheelbase and chainstay can give about the same information.

    last year i just showed up at bromont planning to freeride (buy 100 season pass.) but they had a race . I didn't know it was a canadian national. so i bought a two day expert uci lic. then figured out it was a pretty large event. practiced and raced. couldn't shift but still had fun . the course was rugged. im sure you can pre reg save some $$ i don't know where to find official information. google it i guess. the 1.5 hour drive is looking nice this may compared to 4 + to plattekill
