Thru axle centerlock requires a different lockring that is tightened by an external cup BB tool. Like the park tool BBT-9 referenced in their post below.

Centerlock lockrings

This is going on a 12mm axle. Lock ring has exactly the same spline as a cassette lock ring.

which hubs are you using? I'm assuming it is the new front 12x100 mm road / gravel standard w/ 12x142 rear?

I spect. It's a profile wheel set so whatever hubs. I can just change end caps on the axles to go from qr to thru 12mm

Check out the Abbey Bike Tools Crombie. There is now a dual sided thru axle version, but I think the original dual sided tool had longer splines too.

Jason just started offering a saddle angle and height measurement tool that may interest you as well.

The profile product pages lists the front hub as being compatible with qr, 12mm, and 15mm thru axles. It should use the BB splined lockring since the axle adapter will prevent the standard lockring with cassette splines from engaging. The BB style lockring fits the same centerlock standard but it just changes the tool interface to work with the larger thru axle ends.

The standard cassette style lockring will work with the QR adapter but won't with the 12 mm or 15 mm thru axle adapters. Maybe Profile didn't include both sets of lockrings to go with the hub adapters.

Chris King R45 centerlock hubs use the Shimano Y26N98030/ Chris King#PHB355 Lockring for their 12mm thru axles front/rear.

Profile can probably sort this out. Hope this helped.

My older Shimano cassette tool will fit the internal type, but Parks ones will not.
The Shimano one is very thin walled and the splines have a slight taper to ease engagement.
