ขาจาน Sram Red DUB ขนาด 172.5 ใบ 40ฟัน

DESCRIPTION

Triathlon. Against the watch. Cyclocross. Some disciplines require a "1x" , or single-shelf configuration. And while our X-Range ? dual-chainring assembly demonstrates comparable ease of use, there are times when the single-chainring configuration is more relevant. The SRAM RED® 1 crankset offers the most demanding riders the right proportion of different skills: aerodynamics, durability and simplicity.

Details:

• The transmission with a single chainring simplifies operation and reduces weight.
• The 48 and 50 tooth versions feature direct mount aero chainrings for better aerodynamics.
• Non-aerodynamic chainrings can be installed with just one tool, making them easy to fit.
• SRAM X-SYNC ? chainring technology (with wide-tooth / narrow-tooth alternation) provides maximum chain control.
• The laser engraved top finish is more durable.
• The DUB ? bottom bracket adds durability, simplicity and extends compatibility.
• Can be optimized with a power meter.
• Chain line: 45 mm.
• Tray material: Aluminum.
• Crank Material: Carbon.
