Aluminum and Carbon

[Roadtrip]

Not sure about the materials part of your comment, but the bike sizing is relying on the "professional" not to push you into buying what's in stock or always assuming that a lady HAS to ride a WSD/Femme bike. A good sales guy will take mesurements ( but not always ) or watch you test ride and ask you questions as well as answer all you questions in a non condescending tone, even if it is a newbie question.

Down the road your never going to achieve comfort on a bike that is too big/small and no amount of fitting is going to solve the issues either. Id rather a shop tell me to go down the road then sell me something that will be collecting dust in less then a year. I would respect that and do as much business with that shop it'd more then make up for the loss of that sale.

As to materials, perhaps it's being too eger for others (customers) to agree with your (sales guy) pov on frame materials. Some believe steel is the ONLY materials frames should be built with and others think carbon fiber is going to break in a slight wind. So yes there are some over jelous sales guys that drink the kool-aid the marketing folks print.
