i just fitted the tftuned coil spring conversion to my 160mm pikes on a 2016 mk1.5 aeris.
fitting was a piece of piss but then again i have refreshed a few sets forks and had a fork rebuilding geek with me. the trickiest bit is breaking the loctite – follow the instructions to the letter and you will be fine. the only thing was i fitted the spring upside down to how they wanted me to, as the inside diameter of the coil wouldn’t fit over the spring perch the other way.
initial ride round the unit carpark – wow it feels plush. i used the recommended spring and no preload spacers. i have about 22% sag with no kit – basically spot on. off to les arc tomorrow so will update later.
