Hi I really need to find a stronger rear wheel for my bike, have gone through 3 in last year, and had to get straightened in between a few times. Not sure where going wrong riding mainly red grade trails and only small jumps only weigh 12 stone but the rear wheel manages to get bent about every other ride.
Unfortunately my bike is cheap/old enough to only have the standard 135 quick release rear end, limiting me from alot of the top end options, would rather buy a factory built wheel, but would consider getting a good rim built onto my hub if cheap enough, what can people recommend (last one was a shimano mt500 that lasted only 2 rides). Ideally sub £100.

Thanks
