Help with Fastback fit(5 posts)

Help with Fastback fittimmyh

I'm looking at the Fastbacks on the net and can't test ride one. The top tube for a L is 56.5. Is that actual or imaginary straight tt equivalent? I'm 5'9" with a measured inseam of 31.5". I've been fitted for a 54cm Cannondale and Klein before. Does a L sound right for me? Thanks.

If I were you, I'd ask Supergo - you are looking at getting the frame from them, right?

sorry, I'd also meant to say that perhaps a M would be better for you (judging by TCR sizing, which I know is different from Fastback sizing)
I think so too.Spoke Wrench

I'm betting a Medium would compare better to a 54cm conventional frame. I'd get cheapie stems until I was sure that I had the fit sorted. I'm thinking it might take a couple of tries to get it right.

Good Luck.

I'm a bit over 6' and ride an XL. With a short 110m stem, it's about right; I wouldn't want to be any more stretched out.

With that in mind, I think you'd be better off with a M with a slightly longer stem than a possibly marginal L . Keep in mind, too, that with the seattube angle, raising the seat also lengthens the effective top tube, so even if the medium seems a bit small, the added seatpost you'll have to have out will probably lengthen the bike to a pretty good fit.

Again, I don't know how you like to ride, but I think a large might be pushing it.
