I need some advice.

I am finally buying my first road bike, and have settled on Jamis Quest. My question is whether to buy a 57 or 59. 57 has probably about 4 cm standover clearance, which I take to be about right. However, I am a little over 6 feet tall, 84 cm inseam with sort of a long torso. I am concerned that the top tube may not be long enough. I rode the 57 for a while, and it was fine, but I don't know how it suppose to feel. Hub test suggests longer stem, as did the suggestions on fit by post of ET. It comes with a 105 mm stem, and the LBS said no problem just get a longer stem. I think a 120 might be good.

There was no 59 to ride. I figure maybe 1-2 cm of standover, it would be sort of tight. It comes with a 120 mm stem, and the top tube is listed as 10 mm longer. Maybe I would need a shorter stem for this one.

LBS isn't pushy, but says 57 seems right with different stem.

What to do?

probably is. 59 sounds a little big. 105 stem a little short for a bike that size anyway. Get a stem where when you are in the drops your elbows clear your knees by a centimeter or so. Your LBS should swap stem and get you "fit" for free. Any bike shop that wants to charge you for swapping non fitting parts (Stem, Bars and crank ) you should shop somewhere else.

I'm just shy of 6ft and ride a 57 Quest. If I had it to do over again I would get at least a 59. The length of the top tube is fine for me, but the 5 inch drop from the saddle to the bars was too much. I ended up getting a 135mm/ 15 degree stem turned upward to give me some lift. Right now it's probably as high as it'll get (handlebars have about a 2-2.5 in drop from the top of the saddle), and its fine, but it would be nice to get them slightly higher.

Realize, Jamis measures their "sizes" from center of the BB to the top of the seat collar. That means the real seat tube c-c measurement is like 1-1.5 cms shorter (57=55.5, 59=57.5)

You said you don't know exactly how the bike should feel. My advice is get a bigger bike so you can raise the handlebars. Even with a 59, you will probably still get around 3-4 of handlebar drop from the saddle if you angle the stem straight out. Considering the slightly layed back geometry of the seat tube (73 degrees), that amount of drop should be fine. I'm just trying to warn you that if you're not careful too-low handlebars will com back to haunt you, like it did for me. If you want comfort try to raise the bars to within 1-2 inches of the saddle.

Thanks. I realize that I need to be comfortable if I am going to enjoy riding the bike.

By the way, what do you think of the Quest?
I always thought it was "how you use it"? :-) nmDougSloan
