Fabian Cancellara's (Radioshack-Nissan) le-tour Shimano Dura-Ace rear derailleur .. equipped with aftermarket pulleys and Nokon cables at a quick galance, so I guess he feels there's a need to 'tune' standard equipment?
Nokon is standard equipment. ;)
The oversize pulleys supposedly reduce drivetrain losses.
They are not drilling holes in parts, they are merely using different parts.
ie. I have Shimano drivetrain but I don't use PRO bars.
