Interesting:
(From CyclingNews.com talking about George's Paris-Roubaix bike)
Scott Daubert: One thing I forgot to tell you about is that George is
running with a different fork; it has a longer axle to crown dimension,
and it has a longer rake than the normal Bontrager Race Lite fork.
CN: Is this something new you'll bring into the Trek line?
SD: No, it's actually from Bontrager's Satellite line, almost from
their commuter level, but it has dimensions that are appropriate for
Roubaix. It's an in-house made fork, made at Trek from OCLV carbon,
it's just on a different model bike.
CN: Is it a steel steerer?
SD: No, it's aluminium; it's been blasted then anodized black.
