Mountain bikers love to discuss gear. From tires to droppers, no topic is safe. If often leaves you the impression that cyclists prefer arguing about product over riding.

One topic that is always up for endless debate is whether to 1x or 2x. With more options than ever, it's a valid topic.

To gain a little real world insight into what the pros think, the Enduro World Series interviewed Rene Wildhaber (bike check here) and Katy Winton. Both riders are sponsored by the same frame and drivetrain manufacturer, yet have very different reasons for picking their drivetrains of choice.

For Katy, a 2x drivetrain allows her to rest on liaisons stages. She also prefers the tighter jumps between gears and the wide range. One key feature with Katy's drivetrain is although it's a 2x11 system, she only uses one shifter. This is made possible by Shimano's Di2 Syncroshift feature which shifts the front derailleur automatically. This allows the rider to focus the left side for the dropper post lever.

Rene on the other hand, prefers 1x drivetrains for everything but super steep training rides. From his perspective, 1x setups are cleaner and tend to be mechanically safer come race day.
