  • 44mm head tube for tapered steerer compatibility.
  • Chainstay disc mounts provide for protection for the disc calipers.
  • Modular dropout system lets you choose (or upgrade) your hub system – quick release or 12mm through-axle hubs.
  • Excellent braking – wet or dry.
  • Fewer mud-related problems.
  • The top tube is free of all cable routing for easier portage.
  • Race-ready cyclocross fit.
  • Limited top tube slope for nice balance while carrying your bike.
  • Stainless steel dropouts for reduced corrosion.

It all spells speed and versatility – great for gravel racing cyclocross, light touring/trail riding, commuting and lots of other activities.

We didn’t forget the functionality: you still get eyelets and rear rack mounts plus two sets of water bottle bosses. The chainstay disc mounts let you mount a standard rear rack for commuting or light touring – without interfering with the brake caliper.
