Hi emtb people,
I'm trying to work out how to replace the chainring on my Rockrider E-ST 520? its uses the Brose T drive unit, I've managed to remove the crank arm and then the silver ring screw on the bottom bracket which I thought was holding the spider to the bottom bracket, but would seem I was wrong, it wont budge.
Do I need to use a car brake removal calliper to just pull the spider off or is there more to it?
