It’s been about 6 months since I tossed the Eighthinch Chromo splined sprocket on the trick whip. I’ve been beyond impressed with how this beast has held up. I put in work on this thing just about every day whether it be doing tricks or couriering during the week. As far as I can see there are no bends or cracks in the sprocket, no warping and very little wear on the sprocket teeth. No insert means no slipping so absolutely no issues with that! These little guys are milled 4130 and 48 spline for your BMX cranks. I’m currently running a 33t with my 12t Eighthinch cog and love it. Check these when Eighthinch drops them as you wont be disappointed!
