  • Features

    • High-modulus carbon frame with rear thru-axle dropouts and rear rack compatibility via Rack-Lock seat collar (not included)

    • The lack of seatstay and chainstay bridges allows the full length of the stays to contribute to flexibility, while the rear thru axle ensures precise tracking
