Bike fit

I spent 3 1/2 hours yesterday getting a bike fit.  I was told I need an effective seat angle of 80.9% my current bike will not allow a seat angle greater then 77%.  This seat angle seems quite high.  Does anyone have experience with this?

    What kind of bike do you have?  Is it a road bike, being converted to a tri bike?

    It is a kestrel 4000.  He said I needed an effective seat angle of 80.9 degrees and my bike can only go to 77 degrees.  He sent me an email today stating that the Ventum wouldn't work either.  He recommended two bikes that he carries in his shop.  I am starting to question the entire bike fit process.

    Hmmm..sounds a little fishy.  I can only offer some reading maybe it will give some guidance to at least ask the right questions of the fitter.  Hope it helps.

    according to this article, you can get to 80% (which is pretty darn close!)

    Can you get another seat post to increase the angle? The Cervelo had a reversible post.  Here is a picture of  bike fit I had done by Todd Kenyon at TTbikeFit.com

    Brent, for a few years now, I've done all my fits (and pre-purchase fits) with Todd (TTbikeFit.com). Great results!!! Highly recommend talking to him.
    x2 on Attila's comment .... your LBS's recommendation does sound fishy !!!

    I have email Kestrel to see if there is a seat post that will allow a steaper seat angle.  In what I have read about the Kestrel 4000, the larger frames like mine only allow a seat angle of 79 degrees.

    Brent, I am curious to see how this panned out for you. 

    I too, recently had a bike fit and coincidentally I also ride a Kestrel, only I ride a Talon.  My bike has always served me well, but this year I have been having issues with saddles and comfort.  I won the bike fit in a raffle, a big deal with the seat pressure pad and everything.  Since the fit I was told that my bike can't accommodate the fit that I require, my seat has been dropped a good inch and a half and on yesterday's first half iron aqua bike I had significant knee and inner thigh pain. 

    Please update us how things worked out and thanks!
