Product Description
This Shimano Dura-Ace TT/Triathlon J-Kit is a multi-variation listing that combines the ST-R9180 Di2 TT brake/shift lever with the matching BR-R9270 hydraulic disc brake caliper in either front/left or rear/right configuration. These kits are designed for clean, high-performance hydraulic braking and Di2 shifting on compatible time trial and triathlon bikes.
The ST-R9180 lever was developed for sleek TT and triathlon cockpits, pairing Shimano’s proven Di2 electronic shifting with an aerodynamic brake lever body designed for better grip and confident control in race conditions. Each lever uses a single integrated shift button for intuitive operation.
The included BR-R9270 calipers use Shimano’s latest one-piece mono-body construction for increased stiffness and reduced weight, along with wider pad clearance for quieter operation and easier maintenance.
