Kingsong S22 Pro slider skid caps

The original Kingsong S22 sliders are subject to inward lateral pressure when coming off drops and jumps. This causes the bolt heads that hold the rollers to bind and scrape in the slider channels, causing high friction, scraping noises and damage to both the channel and the rollers themselves. The newer releases have a new slider design with lateral rollers to alleviate this, but for those with the older sliders, these caps will essentially do the same thing. I have put ~2000km on the wheel with these installed and they are still perfectly serviceable as can be seen by the photo. The rollers are showing no signs of deformation due to side loading. 

I have printed them in eSun ePLAst, which is a very tough plastic and seems quite slippery as well. It can be tricky assembling the wheel without knocking off the top caps, although with practice it is quite easy. It is imperative that the side frames are in perfect alignment (which is what you need for the suspension to work properly anyway) to get them in. The top sliders are not really necessary as all side compression comes from the pedals which is around the middle and lower part of the suspension.
