Dam thing won’t let me post pics, but it looks just like a regular crank arm puller for a spuare taper bottomed bracket but this is a French made vintage crank set, while most modern crank arms take a 22mm that threads into the arm it self this set has a 23mm threading on the side of the crank arm so my crank puller that I use for all my cranks is too small and won’t grab the arm itself Sent from my iPhone using Tapatalk
