I am going to buy a Trek Fuel 90 online and need to know what size frame I should get. I am 6 feet tall and a 34 inch inseam. Thanks for your assistance

I am almost 5'7'' with a 31in inseam. My bike is a 17.5 in Trek Fuel '98, which should have a similar frame to the Fuel 90. I love the way my bike fits me, even though it is a little high in the "family jewels clearance area".

Frankly I would go to a store and see how the bike fits before ordering. Start with the smallest frame possible and go from there. Buying a bike without demoing it is a risky thing. And fitting for a bike can be an art in itself. Good luck.

go with a 19-21 inch frame.

I'm 6'0" tall with a 34" inseam and I ride a large Trek Fuel 100. It's a good fit, but like any bike that only comes in small, medium and large, it doesn't fit like a custom made bike. In other words, it might fit me a little better if it was just a bit smaller but a medium is too small for me.
