Works great! Don’t forget to torque to what’s specified. Otherwise you will strip the flange! No slop or movement in discs;

Best adapter I ever got. Fits nice and looks great! Shimano did a great job with this quality and materials are 10/10 looks perfect on my Giant Trance.;

These are the original Shimano centerlock to 6-bolt adpater with the model number SM-RTAD05. The lockring that it comes with works with the same bottom bracket tool.;

Amazon Junkie

All of the other 6-bolt to centerlock convertors use metal pins to loosely hold the rotor to the adaptor then the lock ring clamps it down. That works OK I have one wheel with that system (DT Swiss) but the Shimano system is better. This uses 6 small bolts to positively attach the rotor to the convertor hub then the lock ring goes on to hold it in place.
I saw another review that complained that the 6 rotor mount screws stripped because he used SRAM's recommend torque of 55Nm to attach them. He failed to read and follow simple instructions. The 6 bolts are just there to snug the rotor down to the convertor they are not stressed. The torque spec for those bolts is 2-4Nm not 55. Not even close. Of course he stripped them. 2-4Nm is 18-35 inch pounds that's basically snugged down just barely tight. Then the lockring gets torqued down at 40Nm and that holds the rotor to the convertor and the whole assembly to the wheel hub. It pays to read the instructions (BTW not included with the kit you have to download from Shimano's website). 55Nm is the torque to use for attaching the rotor directly to a 6-bolt hub and SRAM supplies hardened bolts with the rotor capable of withstanding that torque. That does not apply with this system. Read the instructions don't try to figure it out yourself.
This kit is for thru-axle wheels. You can use it for the 9mm skewer type as well.
All that said it is grossly overpriced for what it is.;

These are so simple and come with bolts to mount any 6 bolt rotor. Easy to install and works perfectly. If you travel at all this is a simple way of taking off your rotors for bike bag so they don't get bent.;
