HAI

So I'd like to get a decent single speed mainly for commuting to work in NY ~30-40 blocks or so then take it out afterwords to ride on some extended 15-25+ mile rides

I'm liking the Dawes SST-AL http://www.bikesdirect.com/products/..._al_carb_x.htm for the lightweight alum/carbon would make it easy for me to handle lugging into the storage rack at work and storing in my house

But I have no experience and don't know what I'm looking at so would something like that be good or would this eBay Dawes be suitable? http://cgi.ebay.com/NEW-BICYCLE-TRAC...item2eb302da47

I'm 6'3" and would probably get the 62cm model if I go with the SST-AL
