Apparently it's the biggest non-tandem frame they'd ever made Looking at the figures for my bike though (470mm reach), it's only a big larger than a 62cm Dixie Flyer (465 reach). I was looking at a Dixie, but it was taking a long time to happen and I ended up with my custom alloy instead

The Felt 58cm has a reach of 421mm and the 61cm Bianchi works out to be pretty much the same so you won't gain anything there. The big Felt takes you out to 438mm and there's a few frames around that size IIRC like the Fuji mentioned above. Then there are a very small few frames that reach up towards the 460mm mark
