ขาจานพาวเวอร์มิเตอร์ 12 สปีด Sram Red ขนาด 172.5 ใบ 46/33

The SRAM RED AXS™ powermeter breaks with tradition —and breaks through to new levels of performance.
The product developers of SRAM have reengineered road gearing: reducing front chainring size and adding more range to the rear cassette. This innovative design is called X-Range™ gearing technology. They also maintained a 13-tooth delta on all chainring pairs, ensuring precise shifting for any setup. This results in more useful gearing and better shifting across all configurations. The SRAM RED AXS powermeters are also designed with Quarq DZero™ power measurement into crankset. Thanks to a professional performance-controlled training, you are ready to climb the cycling monuments.

The SRAM RED carbon crankset features a completely hollow crankarm construction called Exogram. As always for seamless, flawless performance and Yaw compatibility, pair this crank with X-Range direct mount chainrings. Like the current SRAM MTB cranks, the SRAM RED crank is also equipped with the universal DUB (Durable Unified Bottom Bracket) crank spindle which can be universally used in all common bottom bracket shells, also increases rigidity. The bearing play will be fine tuned with an adjuster ring.
