Drillium - Drilling bike frames and parts

Yep I agree. But my (weak) point is .. that drillium was tuning of parts in yesterday to improve performance and today tuning is still practised, even if it takes forms other then drilling a hole. I know the direction to WW ;)

Oh btw the pulleys are std 11 teeth .. they've been upgraded I'm pretty sure to ceramic speed pulleys to reduce friction losses.

His TT bike used Berner cages with larger pulleys. Perhaps not used on the road bike due to larger cassette gears?
