Touring frame fit help

Dear more-experienced-tourers

I am looking at a rather relaxed touring frame (my first tourer)


that is 51cm tall (CTT) and 55cm long (top tube). I usually fit well on 55cm x 55cm road bikes (I am 5'11" 32" inseam), but I have only ridden more aggressively set-up frames.

I am trying to see whether there this bike is at least approximately my size, before driving over an hour to go see it.

Thanks for your help.

You might have to raise the seat a little more than you are used to. Far a s I know it should fit ok, and the extra clearance to top bar when stopped may come in handy.

It looks to me like it's nowhere close to your size. The 51cm height and extremely short head tube will likely mean that there's quite a bit of distance between the saddle and bars. I suspect that will lead to a riding position that's more aggressive than you'd want in a touring bike...

Inseam is crotch to cuff, of your pants, which does not include your Feet.
so instead put something in between your legs
[old people the 33_1/3 rpmLP record in its package was good]
then have someone mark the wall how high you can pull it up .

That is stand over height.. it should be an couple inches more than the frame standover

Pulling the front wheel off the ground standing over the bike gives you that

5'11" a 56 or 57 or even a 58, is more what you should go for ,,
in a level top tube frame .. if it slopes down then the seat tube is shorter so Size gets less .

I typically ride a 54 or 55cm frame (though I'm a bit smaller than you) and I tried unsuccessfully to make a 51cm frame work. I could make it work with the seat post at the upper limit, but I could tell it still wasn't a proper fit. I've found that I'm more comfortable at the upper end of my range than near the too-small end.

Interestingly, this Peugeot has nearly the same measurements (51 x 54) as the Giant:

Sweet spot on the saddle to the most common riding position, usually where your hands meet the hoods, is super critical in a touring frame. That is the practical effective tt length, determining how stretched out you'll be for many miles, day after day. Standover is secondary. Unless your dimensions fall within those used for stock frame design, you'll most like have to tweak the ett length of whatever you buy. Stem length and/or seat tube and/or bar type. Only way to know for sure is to buy as close as possible, ride it a lot, and then tweak.

I went through a lot of tweaking with my DF tourer to get it right. It was too big from the get go and my dimensions too far out of the box. No such issues with the bent.

I went with a "Function over Form" stem to get the proper reach and height on my bike.

I think I decided against this frame .. I found a frame in my size to which I am leaning. No need to risk it and end up with an inferior experience (again) .. I finally want a frame that fits like a glove and this will likely not be it.

Thanks for all y'all's help.
