get different hubs that are still like the same size but stronger, u can get em put in some retarted stuff mi mate puts his frames in, it reduces the weight bi 75% yet it makes it like twice as strong, but it is like rlly expsive and takes like a few months
The front hub shouldn't break but the rear hub is crap. I got a heavy duty rear hub that had a 15mm axle. you will have to modify the swing arm and bits to make it fit. I destoyed the original hub and was always bending the axle. now its good as.
