Hey,

I put my cassette on way too tight and I can't get it to move at all.

I've got a chain whip and lock ring tool, and I'm going counter-clockwise, and I've been trying to even bang the lock ring tool to loosen the cassette.

Any ideas?

Long term - buy a torque wrench

short term, get some WD-40 or similar spray lubricant soak the area and leave it for 30 minutes then have a go.

Hammering will just risk destroying other things.

Best advice: HTFU

How long has it been on there? What wheel and what cassette?

Do you remember if the threads were greased? If they might not be, squirt some penetrating oil (or CRC 5-56 or WD40) and let it soak in. Repeat. Then a hairdryer to heat things up and expand them a little.

Do you have an inflated tyre mounted on the rim? This gives much better purchase than a bare rim.

Ok that's kinda what I was thinking, get some WD-40 or whatnot.

I only used a very tiny bit of lube on the cassette body, and yes it's on an inflated and mounted tire etc.

It's a 105 cassette on a dura ace 7900 hub

You are holding the chain-whip in your left hand, the lock-ring tool in your right, leaning over the upright wheel, and pushing down with your right hand, aren't you?

I have had a few tough to release cassette lock rings. Always found the best approach was to apply even, heavy force to them slowly. Hitting them, or trying to shock them into moving is not going to work.

I'll try that when I get home. I broke the chain whip so either I have to buy a new one, or a new cassette for the wheel set I'm selling with my bike - at 4:30 today. So I'm off.

If you had started doing those deadlifts like I told you to, this would not be a issue.

Shurely the bench press is a more appropriate exercise for this task. Non?
