My current one has done me great service on my several old MTBs and previous road bike - all QR skewers ofc and my previous brake discs have all been the 6 bolt versions.
Now I've got myself into today's biking world, I find the thru-axle spacer is preventing the tool teeth reaching the brake disc centrelock lockring, though still ok on the cassette side.
So I need one with sufficiently long internal clearance to reach over the spacer on the disc side - anyone able to point me to such a thing?
