Five spot ett was 24.2inches. Trance us 24.5
Five spot reach was 42.24cm, trance is 43.9cm.
Xl five spot fitted perfect with a 55mm stem and layback post which is why I went for a large trance as the size is almost the same if not slightly bigger.
An xl trance would be far to big ??
You have answered you own question then. Unless……..you have decided you like a bigger bike. In which case the trance could be too small. Or too big, if the five spot was perfect.
Maybe you just thought the five spot was the right size, but actually it was too small and the giant is the perfect fit, but you haven’t realised it yet?
Or it could be that Giants sizing is wrong on the website, I’ve heard sometimes they have different sizing depending on which country. The American Trance could be bigger. I’d check the U.K website.
