Converting 12×135 to 12×142 using this video. Mavic SL’s 29er.
I know it has a dob of thread lock on it, but I’m about to bring out the longer spanners and the force required seems excessive. The wheels are brand new and I will cry if I mess this up. Extremely tempted to put down the wheels and try again tomorrow, **** up time is imminent. Any advice from someone who has done this?

Disk side spacer off and adjustable cap loosened one turn, just like video says. But can I loosen the drive side cap? Hell no.

I will sleep on this and break out bigger spanners tomorrow.
I suspect the short ones cannot break the thread lock.

Could try some boiling water to soften the thread lock.

I would say to stop for tonight and have a fresh look tomorrow. As you say it could be the time you are home to Mr Cockup if you carry on.

Bigger spanners out and kettle on…

Mr Cockup on my shoulder..

Kettle worked, hurrah! and thanks “Dirty Dog”
Got to love this place.

Very glad I was wrong. Good job and good advice!

Yay 😀
