What's the purpose of this bike, Owlie? Is it going to be a go fast bike or is it going to be a errand, whatever bike?

My surly pacer had a ridiculously short top tube for a unisex bike. I'm not a wsd person and at 5'1, I like a 520-540 cm top tube. The pacer had a 490 cm top tube. So that being said, it never really fit me well, so my comments on the bike might be entirely off base since I never rode it more than about 45 miles (painful ones). So I think the fit of the pacer will probably be fine.

Surly's seem like heavy burly frames to me, and I think they're great for touring, commuting, beating up, urban whatever - But I wouldn't buy them for a go fast bike. Maybe look at lemond or bianchi if that's more your plan. Test ride some titanium if that's in your price range. But not all steel is created equal, there's thin, light high quality tubing, and then there's heavy stuff. If you want a go fastbike, look for the former, if you want bombproof errand bike, go with a surly.
