Epessa 170mm Crank Arm - Left Side - Choose Between Diamond or Square Hole

Glenn Shepherd : Used this to replace bike arm with stripped out threads, and seems heavy duty. Fits snug on bike and threads feel very good.

Dopeonarope: This crank arm was a good fit and perfect for replacing a tired one. Feels solid but also lighter in weight than the one it replaced.

jose a.: I was happy to find this to be delivered so quick.
The part is well done and it was a perfect fit for my bike. I am happy with it and it is already part of my bike and training.

raj from chicago: The left crankarm of my bicycle loosened up. I tightened it but it kept coming loose. Inspection revealed the crankarm was chewed up where it slips over the square tapered axle. I ordered this replacement making sure it is the proper length and the hole where the pedal attaches is diamond shape rather than square and 9/16 opening.
Installation consisted of screwing the crank bolt tightly forcing the crankarm onto the tapered end of the axle.

Jim Tadlock: I dropped my new E bike, off the rack.

Did the left crank arm so I had to replace it.

This did the trick, it was easy to takeoff with the crank arm, removal tool, and it was easy to put on with an Allen wrench.

I was very impressed with the quality of the product and how easy it is to mount it.

You don’t necessarily need the crank arm removal tool, But it makes it a lot easier to remove.

This crank arm fit exactly.

In case you’re not sure which one to get, you need to see if your crank is a diamond or a square, and you need to know the measurement in millimeters from the center of each hole.

This got me back on the bike!

Beautor: Item fit perfectly to replace the damaged on on my son's bike. Be careful to select the correct crank axle fit. They are either square or diamond (rotated square).
