I am doing the Sub9 Gravel Grovel in Brown County, Indiana. It is 62 miles, mostly gravel, about 4 miles of trail, and another 4-5 miles of unimproved road that can be really be consider a trail, along with about 4-5 miles of pavement. It has 7 Cat5 climbs in it and about 4200ft of climbing. They have recently dumped alot of fresh gravel on large portions of the course, so alot of it could be pretty loose.
Which bike do I ride:
1)Rigid Carbon Trek Superfly hardtail. All carbon with XTR and King wheels with carbon clinchers and Stan's Raven 2.0 tires.
2)Trek X0 crossbike, Bontrager Race Tubeless wheels with Maxxis Raze 700x35 tires set up tubeless. 105 components, MiniVs.
Both are 19-20lbs. I know the singletrack and unimproved road well and can rip it with Superfly and make up ground. I am also thinking the bigger tires will handle the loose gravel better, so I can be a kamikaze on the descents.
BUT is it enough to make up for just the overall lower rolling resistance and aero position of a cross bike. I am primarily a mountain biker, but am comfortable on both bikes. Wheel/tire weight is roughly equal as the mountain bike wheels are a couple hundred gram lighter than the lower end Cross wheels to make up for the heavier tire weight.
Anyone been in this situation on a gravel race?
