Fair point. This is a fairly flat route with only about 900 ft of climbing, but I use it to go flat-out and see how fast I can go on a gravel bike setup. It's completely unsustainable over longer distances, and I usually shave 3-4mph off of whatever speed I can do on that ride to pace for a 100 mile race.
Is the gravel race fat-bike specific? Or is the surface so rough or soft that you need that bike? I mean, that's an odd choice of equipment unless it's a fat-bike race, or the surface is horrid.
My thoughts, in order that they occurred:
( Wow that's a good pace for two hours on a fatbike )
( gravel race? is it a fatbike gravel race? )
( if it's not a fatbike gravel race, the surface must be rough as a cob, or soft as sand if he's chosen to ride a fatbike! )
Sure, lighter tires and rims will help, but so might pulling a different bike out of the garage
OK you now have your quota of smart-azz answers, hopefully someone will chime in with their tire recommendations.
I appreciate the comments, smart-azz or not
Most of the races I've been to have had a fat bike category, and ever since buying my Ice Cream Truck I've wanted to give it a shot. I have a Soma Double Cross that weighs 15 lbs less, but rolling 100 miles on a fat bike is a new and exciting challenge. I know a couple of guys that can roll their fat bikes just as fast as the average person can ride a cross or gravel bike, and I'd really like to get to that level in the next couple of years.
