Safety caps offer a lot of protection during a fall. The crash caps absorb the initial impact but also prevent the bikes from flipping over while sliding. We have crash caps for the front fork and drive shaft.
We have crash caps for the front fork and cardan axle. The drop caps not only protect but also provide a nice finish because the drop caps go all the way through the axle itself. The front fork and cardan shaft are expensive parts to replace, by using the caps you limit the damage.
