The lightweight tubular full carbon 60mm deep rim provides improved aerodynamics, increased rigidity and excellent inertia for sprinters and TT specialists. It features an easy-to-use Center Lock rotor mount for disc brakes and stainless steel butted and bladed straight pull spokes for optimal balance and rigidity. High lateral rigidity is achieved through wide flange spacing, while labyrinth double-contact sealing keeps out water and dirt. The wheel utilizes an alloy cone with integrated steel Borozon treated bearing races for a super mirror finish that reduces friction. The freehub uses direct engagement interlocking faces for quick power transfer, and the cold forged, machined aluminium hub shell with an oversized 7075 alloy axle minimizes weight. This wheel is compatible with 142 x 12 mm axles and 12-speed drivetrains.
The Shimano Dura-Ace R9270 C60 Tubular Rear Wheel is engineered for competitive road cyclists, sprinters, and time-trial specialists who prioritize aerodynamic efficiency and high-speed inertia. Featuring a 60mm deep carbon rim, this wheel offers exceptional rigidity for power transfer, though it requires a tubular tire setup and is exclusively compatible with 12-speed disc brake systems.

Extended Product Information
FAQs
Is this wheel compatible with 11-speed drivetrains?
No, the R9270 series freehub body is designed exclusively for Shimano 12-speed road cassettes.
Can I use clincher tires on this rim?
No, this is a tubular-specific rim and requires tubular tires that are glued or taped to the rim bed.
What is the hub spacing?
This wheel uses the modern 142mm x 12mm thru-axle standard.
How do I maintain the bearings?
The wheel uses a traditional cup-and-cone bearing system. You should occasionally check the preload and clean the races if the wheel starts to feel gritty.
Is this wheel suitable for gravel riding?
While structurally sound, the 60mm rim profile is aerodynamically optimized for road racing rather than loose, technical gravel surfaces.
Troubleshooting
Feeling play or movement in the rear axle
Adjust the cone-and-cup bearing preload using the appropriate cone wrenches to eliminate play without binding the rotation.
Freehub engagement feels sluggish
Check for debris near the engagement faces or inspect if the internal grease has become contaminated; clean and apply a thin layer of light grease if necessary.
Wheel is not spinning smoothly
Inspect the labyrinth seals for debris and verify that the Borozon bearing races are free of dirt ingress.
Pros and Cons
Pros
Outstanding aerodynamic profile for high-speed cycling
Extremely high lateral rigidity for efficient energy transfer
Requires tubular tires, which are more labor-intensive to mount
Compatible only with 12-speed drivetrain systems
Deep profile can be sensitive to crosswinds
Setup, Compatibility & Care
Compatibility: Designed specifically for 142x12mm thru-axle frames and Shimano 12-speed cassettes.
Braking: Requires Center Lock compatible disc rotors.
Maintenance: Periodically check for lateral play in the axle. The labyrinth seals do not require frequent lubrication, but the hubs should be kept clean to maintain the integrity of the sealing system.
Storage: Store the wheel away from direct sunlight to prevent premature aging of tubular tire glue or sidewalls if pre-mounted.
