Context & Notes

• The Exploro Ultra and Ultra Boost share the same core design philosophy, focusing on aero performance while increasing gravel tire clearance compared to earlier Exploro models.

• Official 3T literature confirms internal routing, flat-mount disc support, and mixed 700c/650b wheel compatibility.

• Because this is the OEM frame only, no components (fork, headset, seatpost, drivetrain) are included or assumed. Buyers should verify parts compatibility for their build plan.
