I ride 60. I don't think this is your performance road bike, but you could still keep it and build it up for other types of riding. A 60 won't have much difference in TT length than a 58cm (typically) so it may still "fit". It would be more of a "French Fit" as they say.

That's the problem- my 58 is French fit (which I prefer). 60 would leave the seat slammed.

then it is not a problem, you know what you have to do, sell the bike. You can relax now knowing that you cannot regret your decision to sell.

[QUOTE=johnnyboy1;16418826]Thanks for the comments. I wanted reasons to keep the Cooper, so posted in C&V! But I made a mistake- I didn't measure it first. It's 60- so probably too big. My other bike is 58 and fits perfect.[/QUOTE

I had a TSX bike fall in my lap that is 2Cm to big for me. Changed out the 100mm stem for an 80mm and it fits like a glove. If you can manage the standover hight you should be good to go with shorter stem and some time fooling around with your fit
