So as a rule of thumb for street riding , i'd wanna shoot for some thing between 75 and 90 GI? maybe a 52x16 or 15??
riding 90GI on the street would seem to me an excersise in torture. personally i'd shoot for anything between 60 and 75. it also helps that this is a pragmatic choice when you're building up your bike: a 16 tooth track cog is probably the most common (in dura ace anyway) and it's easy to find either a 39 or a 42 tooth inner chainring from a 130bcd double kicking around somewhere...
