Hi, I have a 1000w hub motor on the rear of my GT aluminum frame. It seems to have bent the dropouts a bit and slips out even when tightening under any significant throttle. How could I fix this?

I'd get on the torque arms, 10 bucks for a 300 mm x 10 mm x 40 mm piece of steel, a couple hours with a grinder and a drill.Philaphlous said:Bummer dude! I always worry about mine since I'm running close to 2kw through my 1000w hub motor... I have a chromolly frame though with steel dropouts... I check them regularly and they're great thus far! I have plans for a torque arm..just haven't got around to it yet... that's my summer project!
Actually, if they're aluminum, they'll probably jsut break off. Depends how far they were pushed, type of alloy, heat treatments, etc.Yungyakz said:what i am currently doing is i hammered the droupouts and bent them back ( this wont fix the problem and will go back to being bent)

If they're steel, they'll bend repeatedly before breaking. Also dependent on the above stuff, but much more tolerant than aluminum.
Regarding the cost of the torque arms in differnet sellers, sometimes tha't sjust greed. But it can also be the materials it's made of (soft or hard, etc), and the preciseness of machining (tightness of the axle fit preventing rocking/spinout).
FWIW, all of the ones like those are copies of Grin Tech's design, so if you want the real one, that may be better than the copies, go to http://ebikes.ca
