a big mistake my old pal, tensile have isis threads witch means you will have a isis bottom bracket, that tool is for a sqaure taperd crank and bottom braket witch means it wont work, unless u put a 5p inside your crank then it will work because when you tighten it, it will push agaimnst the 5p and force the crank to start loosning and come off.....it worked for me or if you dont want to bodge it just buy the propa tool here
