The Northshore Overlord 6 hour enduro enduro on Fromme Mtn, North Vancouver, BC is coming up again August 25. This is a non-stop ride all the downhill trails you can without repeating a downhill trail for 6 hours, not a stage downhill Euro enduro.

Last year I spent most of the time in 32x34 on the climb trying to conserve energy
and barely pedalled on the downhills, again to conserve energy.
I have been thinking that a single speed with close to 1:1 gearing would work well for this type of event, or for Fromme Riding in general.
