What bike?

There will be a diverse range of road surfaces on the route (smooth dirt, washboard, sand, and rocky, tree littered trails and some alpine grasses and steep decents), the optimal bike for the Grom Pre is somewhere between a gravel bike with 40mm+ tires and a mountain bike with 2.2” tires.

This route is certainly do-able on less and more if you don't have a bike within that range but know your ability. 

There is a break down of what is on my shit hot Crust Bombora here. This would be a good style of bike to ride.
