Shimano Ultegra FC-R8000 Left Crank Arm - 170mm Hollowtech II Compatible

Cyclists, if you're dealing with a damaged or worn left crank arm on your Ultegra setup, this FC-R8000 replacement is exactly what you need to get back on the road.

This is the genuine Shimano Ultegra left crank arm in 170mm length, designed specifically for Hollowtech II bottom bracket systems.

The black finish matches the Ultegra aesthetic perfectly, and the build quality is exactly what you'd expect from Shimano - lightweight yet incredibly durable. Installation is straightforward if you're familiar with Hollowtech II systems, though you'll want to make sure you have the proper tools and torque wrench to get everything set up correctly.

The 170mm length is one of the most common sizes, making this compatible with a wide range of Ultegra setups out there.

Whether you crashed and bent your current crank, stripped the pedal threads, or just need a replacement for a worn component, this left crank arm will have your drivetrain performing like new again. It's always frustrating when just one part of your groupset fails, but replacing individual components like this is way more cost-effective than buying a whole new crankset.

The Ultegra series strikes that perfect balance between performance and value, giving you professional-level quality without the Dura-Ace price tag.

Get your bike back in top shape and enjoy that smooth, efficient power transfer that Ultegra is known for.
