My front wheel on my bike is a 700c road bike wheel. Unfortunately, when I am riding hard, the saddle swings from side to side and I can hear the spokes creaking against one another. I weigh 235 lbs. Should I get a heavier grade wheel, or is there anything I can do to repair this issue? The sway gets bad enough that the rim starts to rub against the brake pads when I really step on it.
