like me? being fit obsessed (if you are a cyclist you are obsessed. period), once in a while i read a spot on sizing post by C40 and start tinkering with thoughts of finding me a 1cm smaller frame. problem is: mine is a great frame, not made anymore. light steel, lugs and steel fork. i won't add another bike to the stable right now. either swap or keep. any thoughts?

My Merckx, which I bought used and sight-unseen as a "57" appears to be more of a "58." It actually is 57.5 c-c with a top tube of 57.3 or so, which corresponds to the 58 on the Merckx sizing charts. I use it as a second/rain bike and it's no big deal, still fits fine with an 11cm stem, and there is actually more a standover than on my custom bike because of the lower bb and slacker STA. It just feels a bit large to me--which I'd prefer to feeling too small. But if it was an only bike I'd replace it. But as it is I like the color, the flat fork crown is cool, it was cheap to build up, and I FINALLY got fenders to work on it so it's a keeper.

my 54 has the same numbers as a 53 steelman and a 53 pegoretti:
73.5 sta and 54.5 cm longer top tube. front end is the same as a 53 pinarello
it has the same numbers as a medium compact, my size.
i'll end with a stiff alum frame if i give up on this frame cause thta's what's available around here but that extra 1 cm on st over height is the excuse to obsess on aother frame.

When I got back into cycling about 4 years ago, my old size 57 c-c Bianchi seemed too large. I consulted some fit formulas, like Colorado Cyclist, and became convinced that I needed a frame about 1-2 cm smaller. I tried several smaller frames, but just couldn't handle the larger drop from saddle to handlebar. Now I'm back to riding a size 57, but in a Merckx, which has a shorter top tube in my size than most frames. It fits just right.

If you mean only a longer seattube than the book might dictate, no worries. Clearance can vary from 2 inches to .5 inch with no performance issues so long as you can get your bars as high as you need.

The main problem folks have with a "slightly bigger" frame is with reach. If you can't get the right reach with a 9 cm or longer stem, then it can affect performance.

I have three bikes ... kinda a "Goldilocks" thing. One a little too small (aging steel), one a little too big (bargain aluminum), and one "just right" (my Look 386) and they are all fundamentally okay. I log plenty o' miles on them anyway.
thnx everybody and...colker1

i already have a 12cm stem. now i guess the size trouble is more of a psycho/ neuro/ obsessive compulsive thing. it comes and goes after 12 hrs...
I rode a frame 2cm too long until I injured my neck.Dream plus

I've got long arms and legs proportionate to the rest of my body, so my 56cm Cannondale had the correct standover. I had to move my seat a little too far forward to get the reach correct. I rode it for 10 years. I probably should have put on a shorter stem long ago. On one ride I started getting pain in my neck that no amount of drugs would stop. I stayed off the bike for a while and got some PT. I began riding it again but, eventually got a 54cm Colnago which fits me better.
Switch from 62 to 64 revitalized my cycling enthusiasmCory

I'm too tall for the in-stock bikes in most shops, and for years I let them talk me into 62cm frames with long seat posts. When I got my Atlantis, Rivendell's fit guide put me on a 65, which they didn't make at the time. I ordered a 64 in preference to a 68 (the next size up), set it up per Riv's advice, and it made a huge difference. I could ride at least 30 percent longer in comfort. I'm thinking about a Redwood now, and if I get it, it'll be a 65.
The moral: I'd consider carefully before taking a chance on going too small. The drawbacks outweigh the advantages, IMO.
