Bike questions

Tires, ebikes, cut offs

More on the FAQ page.

Yes. There is an 11:30am cut off at the entrance to Rowena for the 100K Gravel Enduro. If you reach this point after the cut off, you turn around and head down Lefthand Canyon.

You will see everything from road bikes to mountain bikes. Because the course has gravel, we recommend tires at least 25mm wide. Knobby tread helps with traction. Gravel and cyclocross bikes are the most common, but on a dry day a road bike with wide tires might be faster. You will get the most high fives on a fat bike.

Yes, you are welcome to ride an ebike, but your time will not be eligible for prizes. You also cannot use an ebike to help another rider get a better time.

Pick a distance. The party is included.
