Today I own a RST Champ fork with 100mm of travel.
After doing some research I found that there are 3 travel options 80mm, 100mm and 120mm.
I also find out that the adjustment is done by adding or removing things called "travel spacers".
I've done a lot of research but I couldn't find where are they inside the fork and how does it look like.
RST YouTube channel doesn't explain this, fork manual doesn't either and I couldn't find nobody even doing this adjust in their forks...
