From the desk of none other than Rob English, http://
www.bikefriday.com/gallery/robenglish, due to race a recumbent in
RAAM, so he should know...
Three things I think:
1. Gearing. Greg doesn't say if he is spinning out or not, but with
only a 89" gear (the 406 wheel is about 18.5" diameter), compared to
120" on a typical 700C bike, he needs a bigger chainring.
(or that Capreo! Some people use both, like BF Club of Austin, TX's
Ron Neher and his 62 tooth chainring+Capreo http://
www.bikefriday.com/gallery?imageId=2262 - LC)
2. Tyres. The smaller wheels seem to amplifly the difference in tyre
rolling resistance. The fastest tyres I know of in the 406 size are
the Schwalbe Stelvios (get them quick before they stop making them
(or switch to a 451mm bike like the Pro - LC)
3. Aerodynamics. I don't know what handlebars are being used, but
assuming the typical mtb bars on a PL, the upright position and width
makes a huge speed difference compared to drops, even when drafting.
( I will stop butting in - LC)
Hope this helps!
