There is no secret that I really like the 26 inch wheels on my LHT. It is looking more and more as if my Gunnar may well be a true custom size to me rather than a stock size (though we are still determining that). If we DO go with a true custom size, I am wondering what advantage there might be to 650 wheels over 26 inch wheels - if any.

I understand that if the fit is right that it wouldn't matter if I had 700cc wheels - would there be an advantage to 650cc over 700cc? I understand the main reason for using 650cc wheels is to decrease toe overlap for smaller frames. I know I shouldn't be prejudiced against 700cc wheels due to my experience with the Trek 7.6 FX WSD - that 15 inch bike was simply too large for me.

I want to stick to 26 inch wheels if I can, but I don't want to reject something that would work out of my Trek experience. I am also researching the tire widths available for 26 inch and 650cc wheels to see what is available. I don't want really skinny tires, no skinnier than the equivalent of the 700x28cc tire at most.

I feel like I am getting in over my head, any tips at what I should consider? This is meant to be my light go-faster bike for club rides/centuries. No racks, fenders only - my LHT is built for carrying stuff, all day meanderings and touring.
