Which part breaks the most? One answser for just normal wear and tear, and one for crashes, please.
Front gears when running a one-way tend to go easily for me. I've replaced three sets. I've gotten a lot of laps down with mine and I've gone through 3 sets of front gears, one titanium front axel, one drive cup, and one wheel bearing. That also represents three major crashes though too, so I can't complain.
Nothing appears to be "wearing out" however.
