The Cenos X4 Pro is race-ready pinnacle of everything we’ve learned from years at the highest levels of competition. It simply beats the competition at a stunning 1250g for a 30mm internal width rim profile with a bead size increased to 3mm. We have tested them real-world in Cape Epic, Swiss Epic, 4Islands and other toughest and rockiest races and it performs flawless. We designed them to be paired with wide, high- volume tires and run low pressure for the lowest rolling resistance. For the best performance we lace them with the mix of lightweight CX-Ray and stiff CX-Sprint spokes. We use Sapim Double Square nipples which allow to increase spoke-nipple thread interface by 28% for added durability. Choose from our own Ova M or DT 240 hubs.
