yes i will say it will be fine cause it will be.
i have been using one for a good few months now, ask wheeler or goddard. i ride with them quite a bit and they know ho wmany mech hangers i have gone through.
since having the freshproducts tensioner i have had the same hanger and it is still perfect after running it for 2-3 months, which is amazing for me.
the thing is, when you land on the tensioner it is normally just pushing it straight up, all this does is move the tensioner up and just makes the chain go slack (if you run it tensioning it down.) so there isnt really any sideways force going on it to break a chainstay or what ever off, i have landed on my countless times and the only thing that bent was the actual "arm" of the tensioner but that wasnt alot and i just pushed it back inline.
i hate the way people do this, yes i freshproducts did give it to me, yes that makes me want to help him out by trying to promote thier stuff. but i will be honest with you, if i thought it was shit i wouldnt have posted in here telling others to get one. if you dont believe me on that one fair enough, but im sure others with the tensioner, fatmike, stan blah blah will give you the same.
i havent tested and other tensioners but i hear nothing but problems with all the other tensioners people use so i can only go from that to say it has to be the best tensioner on the market.
oh and i did the thing with the steel plate making the hanger stronger and that did work very well too, but i still bent hangers.
the freshproducts tensioner is the best and only way to cure the problem
