I have this
crankset.
Product Description: Shimano M442 Mountain Cranksets. Removable Chainrings; Spider is not removable Square spindle hole
I need to replace the outside ring due to wear and have never replaced an outside ring before. However the description says "not removable spider", what does that mean? Also when i replaced the middle ring I ordered a steel ring because I believe all of these rings are steel, can anyone confirm this?
