Thanks for the heads up on those brakes ... I will definitely get some. I like to fit my bike with a brake for alleycats so I don't have to ride as slow. Generally I don't ride that brakeless track bike in the streets ... but the other bike I ride in the streets is also brakeless ... although it has a lower ratio. Yeah, I don't think an aluminum bike is overkill for the streets ... most of my friends will tell me it is. But I think it is as durable as any of my steel bikes. Mostly I think the aero shape is overkill but even then I don't really care either way. My steel rig has a more compliant ride so it's a bit more comfortable.
When I get these nice wheels, they are DEFINITELY not going to see the urban streets, where they would get trashed. I will take them out for longer rides on a road bike (swap the front) or just ride them on the velodrome.
I admit the helmet thing is dumb.
