Please subscribe for more BMX content coming! This is a video with some installation tips for the Profile Column Cranks. They are 22mm splined cranks and there are no holes for a sprocket bolt, so you have to use a spline drive sprocket. I also give some tips for using the right spacers for crank spacing and proper chain alignment. Don't use those cone washers just because they look good if they are too big for your application. I learned that from watching Phu at Epic BMX! In this video, I show how the removal/install tool supplied with these cranks did not work for me without modification. They do not get the crank arm far enough onto the splines. My bike is standard sizing with 68mm American shell, so with the cups it measures exactly 73mm wide outside to outside, which is a standard BMX size. The install tool only got the crank arm on about halfway. At this point, I could have starting beating it with a mallet, but decided to find a better option. I found a metal spacer that worked perfectly. I had just cut 3/4" off the top of my 1 1/8" fork steerer tube, and used that as a spacer between the sleeve piece that comes with install tool. It worked perfectly, thank goodness. Reading some of the comments on the Profile video for the Column install, I feel for people who spent $250 on these cranks and can't get them installed properly - lots of comments on there with upset people. Profile should include a spacer like the one I made, or make the sleeve wider by about an inch. Another tip is that a 22mm socket (the big ones for a torque wrench) worked perfectly as a sort of sleeve punch to get the sprocket started on the spindle. And one final tip, kind of unrelated, is about installing the bottom bracket. This Profile bottom bracket tube spacer was about 1mm too wide. When you are pressing in your bearings (or screwing in the cups), don't go all the way at once. Go slowly, and check to make sure your spindle is still spinning freely. I pressed my American bb cups in all the way, and the bearings were binding on the sleeve spacer because it was too wide. It was not fun fixing it. Cheers!
