The unspoken benefit of "compact" frames was that a retailer didn't have to stock all those sizes of bicycles to fit all those people.

Now we need another wheel and tire size? Is this to run the small LBS out of business because they can't afford to stock the SKUs for 26, 700, 650, and 29, and you need a retail giant like Performance to make sure they have everything for all those sizes?

(Written with tongue firmly in cheek. I let my TP membership lapse about 5 years ago because I noticed they didn't have most of the stuff I wanted to buy either in the shops or on-line.)
