Drillium - Drilling bike frames and parts

^ Some modern drillium

Drilled cogs. I think On-One's cheapies come with holes in 'em anyway.

They look crazy. I wonder, if they're aluminium or steel? I'm guessing aluminium... Do you think they're stiff?

When there's marginal gains to be made and when the difference between winning and losing is being measured in hundredths of a second, these things can make a difference, but on the commute or Sunday morning club run, they're not exactly critical.

With that mentality, why are you on here? hahahaha It's ALL about the hundredths of a second! (which could have been gained by not wearing socks, or going bald, but that's irrelevant)
