Car Axle stand? not got one of those. Im not sure i even know what one is? Is it like the jack?
Sort of like a jack without the jacking bit 😉
If you're not sure what all the screws do, take time to look at the mech before you fit it, flex the mech by hand and get a feel of how it moves and see where the screws make contact with the stops.
There's only 3 screws – the H and L are side by side and adjust how far the mech can move at both extremes of the lever (ie High and Low gear) and the mysterious 'B screw' which adjusts how close to the cassete the mech hangs.
Most problems come from randomly adjusting the screws or problems with cable routing – I only find it easy cos I've fecked it up so many times and learned from my mistakes 😉
