so now that i'm ready to pull the trigger on a bike, I find they are out of my size. I was looking at the mercier kilo wt from bikesdirect.com. it's a wide tire, cro mo single speed. I was looking for the 53cm. i'm 5'10" but my legs are on the short side. they have the bike in 56cm and that's just the slightest bit on the tall side for me. I had my heart set on this bike and nobody has anything even remotely similar. what would you do??? HELP?!?!?

BD -- wait a week for next shipment, don't be color specific. Or, a new model in 2 months with similar specs. If you know your fit, stick with it; especially on a frame that has many comparable competitors.

unfortunately this bike has no competition. only thing I can find that comes close is the steamroller, which will handle a smaller tire and the frameset is almost as much as the kilo. I hope they're getting more in but in my limited experience with bikesdirect, when it's out it's out. in terms of fit, this willo be my second road bike. my first was a 56cm that I couldn't ride because it had tiny little tires and I weigh almost 300 pounds. this is why I need the larger tires.

As a fellow Clyde, I generally like my frames a little bigger. Too small and I feel like I'm all over the bike. I'd say get the 56. You can swap a 0 setback seat post and a shorter stem if necessary.

you can buy a vintage, lugged chromoly bike and convert it to single speed for the same cost, and then have something nicer and more interesting now and more valuable years from now.

Fit is the most important thing. IMO, I would NEVER buy a bike that doesn't quite fit and try to make it fit.

If it doesn't fit, you musta quit.

What makes you think the 56 cm is "the slightest bit on the tall side" for you? The 53 cm has a 547 mm effective top tube. For most people 5'10" tall, that would be too short. Bikes have to fit in the horizontal dimension as well.

well, I had a dawes sst which had the slight compact style top tube and when standing over the bike it was pretty much up there. I didn't stand on my toes or anything but I would hate to hop off the thing during a quick stop and jam my balls on the top tube. I think i'm gonna pull the trigger on the taller bike. I believe it will give me a more relaxed fit, which as a larger rider I think would be better for me.

Very few people hop or come off a bike so that both feet hit the ground simultaneously. The ones that do are usually in their first week of learning how to ride a bike. I'm 5'10 with relatively short legs (82 cm floor-to-crotch), the top tubes of all my horizontal-top tube bikes have all contacted my balls with both feet flat on the ground, and I've never suffered from this in decades of riding. Don't size a bike by standover, it's a bogus concern.

32.2" for 5'-10" height is about average leg length.
That's what I was thinking. I have the same dimensions and I've never mashed the twins on the top tube of a 56cm frame - not even the one bike I have with a horizontal top tube.

see, i'm not quite sure how to measure my standover. I stood against a wall and put an angle between my legs and flat on the wall. but i'm not sure whether I should just put the horizontal of the angle kind of casually up to my nuts or if I should jam it up there, so I came up with a couple different measurements. in any case I think the 56cm is gonna work out for me. I've been doing this for a while and I know how to ride a bike. just that this will be my first "real" road bike. I've always ridden mtn bikes and I know how they should fit me.

If the angle you used was a thin piece of steel (like a carpenter's square), your reading may be off quite a bit. Use something that's about one inch wide, like the spine of a book large enough to reach the wall behind you.

Move your package out of the way and bring whatever you use up hard enough where it will approximate the pressure of a saddle at low speeds or while coasting. That's quite a bit--you should feel contact with the pubic bone. "Cram" is the word here.

You getting different measurements is normal. Depending on thickness of the horizontal up against you and your accuracy in squaring up the angle or book, that measurement can be 3 or more centimeters off. To get a good reading, do the procedure three or four times and use the average from those readings.
