I’m having a bit of trouble removing a track sprocket. Is it a really bad idea to leave the lock ring off and go for a ride pulling as many RAD SKIDZ as possible in an attempt to loosen it?

park big ass 30 quid chain whip will shift it 😉

Remove lock ring.
Place Rear wheel against a wall with somewhere for you to lean. Mount Bike and Back pedal like mutherF’er

Another way of doing it here:

cheers fellas, I’ll try the bodging methods tonight. Don’t really want to buy another chainwhip though as i have (a now somewhat bent) one already.

If none of that works I’ll skid it down to the LBS tomorrow armed with biscuits and my dentists details.
