This 175 mm left-hand crank arm is listed for the Shimano FC-R345 crankset in silver. It is intended as a practical replacement when the original left arm is damaged, worn or no longer safe to reuse, helping you restore a familiar pedalling position without replacing the complete crankset.
The matching FC-R345 configuration is specified with a double 50/34T crankset, a 9-speed rear drivetrain and an Octalink interface. Check those details against your bike before purchase: the crank arm must match your existing interface and crankset arrangement for a secure installation.
A crank arm replacement is also a good opportunity to inspect the crank bolt and mounting area. Correct tightening and regular maintenance matter because repeated pedalling loads can work a crank bolt loose; continued use in that condition can damage the threads and prevent the arm from being securely reinstalled.
A practical replacement for a cyclist or mechanic repairing an FC-R345-equipped bike that requires a 175 mm silver left crank arm.

Matches the listed FC-R345 crank configuration and preserves the existing crank length when replacing a like-for-like left arm.
Silver finish
A straightforward visual match for the silver FC-R345 crankset configuration.
Octalink interface
Confirm your bottom-bracket and crank interface is Octalink before ordering.
For 9-speed setups
The associated FC-R345 configuration is listed for a 9-speed rear drivetrain.
Double crank format
Designed around the double-chainring FC-R345 arrangement.
50/34T configuration

Replacement-focused component
Useful when the existing left arm is worn or damaged and the rest of the crankset remains serviceable.
Generic is a catalogue designation for products presented without a distinct store-brand identity. The term describes the retail classification rather than a separate manufacturer history or geographic origin. Generic-labelled products can still have clearly defined specifications, standards and compatibility requirements. For this component, the catalogue designation is retained while the fitment details identify the relevant road bottom bracket application.
