Sizing yourself for a bike?
 

This may sound moronic, but what is the best was to size yourself for a bike, besides going down to the LBS? I realize that the inseam measurement was commonly used back when I was riding a decade ago, but I've been out of the loop for ten years and now wonder are there more up-to-date, advanced methods used to decide size/fit?

Yes. Search the net. There are may complex formulae; it goes way beyond in seam and includes arm length, for example, and usually torso length. Advanced calculators, I believe, have even more measurements. but arm, torso, leg (not inseam exactly--usually measured with more tension) are pretty standard in fit kits.

You can pay a bike shop to do it for you if you want; it's usually refundable if you buy a bike there.

There is much more to bike fit than just body dimensions. Two people with the exact same body dimensions may prefer different frame sizes and geometries. You need to factor in your fitness level, prefered riding position, body flexibility, and intended use. Watch the guys in the Tour de France. Unless you are in the same physical condition as them, you are not going to be comfortable with their riding positions. Most beginners will prefer a larger bike (or at least a bike with a taller head tube) so they can get a more relaxed riding position that is comfortable to ride at lower speeds.

This sounds like the sensible answer instead of the cookie cutter BS that I normally hear. FYI Riding a frame with know dimensions and understanding something about them always helps you with future purchases.

One of the best answers I have ever read. This is exactly what my fit did for me. Good Luck. :)

I like that one at Cometitive Cyclist. Reading about their 3 styles of fitting was interestering. Turns out my "fast" bike pretty much matches an Eddy Fit, and my Touring Bike is more of a French Fit. The fast bike had a 4 inch drop to the bars when I got it, and now that I've played with stem rise and length, I'm much happier with about a 2 inch or so drop. I think that this one line from their site sums it up
Off to breakfast....
