Query: Excellent product for 45-degree offset spindle hole!

If you are looking for a SR Suntour left crank arm with a square spindle hole which is 45 degrees offset from the spindle holes on most crank arms, this is the product you need, insofar as the 170mm crank arm length is the length you need. At the other end of the crank arm, the female hole for your pedal to screw into is a standard 9/16" threaded. Note that there are Suntour crank arms which in which the square crank spindle hole is configured as shown in the stock photo for this item listing; however, this crank arm, as mentioned, is 45 degrees offset from that shown in the stock photo.
