Trek Fuel EX 9.8. Gorgeous sunny day, got up to 80+ degrees, mild East wind all day. An epic ride on a really nice bike. Rented from Arizona Outdoor Adventures (REI) in a Large (XL was taken) in Scottsdale, about 15 minutes South of the McDowell North Preserve. Started the ride at the Pima Dynamite Trailhead and covered a good portion of the whole park. The bike was awesome, going to try out the XL next week if the weather holds. So nice to be able to just fly over rocky sections as if they weren't there. It's a slow climber, but not surprising as the bike weighs North of 30 lbs. Good descender with the dropper seat post, but it took some getting used to. broke the saddle with a few miles to go but it wasn't an issue. Guy at REI said Trek sent out a heap of saddles with bent rails, so it was warrantied. Longest ride (time) since I've been out here, great hard workout.
