Any Clydesdale ever taken a Specialized BG Fit? Or at least parts of it? Like saddle and cleat/shoes?

Can they detect your sit bones even if you are a fat ass?

I'm thinking of getting one with my new bike. What do you guys think?

I don't know about the whole fitting thing. I did use the Bontrager version of the saddle fitting thing. Basically it's just a pressure sensitive plastic seat. You sit down and the gel type stuff in the seat cushion gets displaced depending on pressure. Where your sit-bones are there is the most pressure. They measure the distance between the 2 'depressions' where your sit bones were. Pretty simple actually.
I can't comment on any other specific fitting.

Thank you, sir. Do you know if fat plays any role in the measurement?

If the shop offers the service, there is nothing wrong with having it done. Saddles are so personal anyways, they might get you started in the right direction.

Thanks, exile. I'm just concerned about fat interfering with the measurements! :|

Fat shouldn't interfere with the measurement. Usually you sit on a gel pad and they measure from the center of each dimple from the lowest depression point. Its the ischial tuberosity bones (sit bones) that cause the deepest depression.

Thanks for the clarification. I guess if BG Fit didn't apply to fat people, they would have told me...

Specialized has a BG Fit product line and also a BG Fit service that will fit you to your bike (or vice versa), regardless of whether the bike/parts are made by Specialized. IMO, there's nothing magic about either the BG Fit parts or the fitting service. In fact, I'd have to say that BG Fit saddles are universally the worst saddles I've ever ridden! I've tried a number of them and they were all terrible for me. Remember: the Specialized ass-o-meter only works for Specialized saddles. There's no universal way to measure saddle width or sit bone width, so the numbers you get from Specialized won't necessarily apply to any other saddle brand.

The fit service probably has a much to do with the person doing the fitting as anything else. I haven't had a BG Fit, but I have watched the process. Didn't seem to be much different than any professional fit I've had done... unless you get to the Supremo-level fit that uses lasers, video cameras... and $300 from your wallet.

the lbs had me use it, and after wards I threw out a seat that was smaller than the 155mm size recommendation. While I have yet to actually use a specialized saddle, I have found that it got me into the right ball park. The saddle that came on my road bike was 144mm. Now i just have to find the saddle that I like.

Here's how you can find out on your own, place a thick piece, or two layers of cardboard on a flat surface, and sit on it with your torso leaning forward. Draw circles around the depressions left by your sit bones on the cardboard, and a vertical line through the middle of each. The distance between the lines is your sit bone width. Now you can overlay that width on any saddle to be sure there is adequate support.

If you find a fat layer is preventing discrete impressions, do something to create extra sitting force. It also may require a few extra layers of cardboard.

The distance between the sit bones is dynamic when peddling, the static measurement is only a guideline.

Thank you very much for this advice!
