Why We Like The Centerlock to 6-Bolt Rotor Adapter

Shimano's Centerlock to 6-Bolt Disc Rotor Adapter is a pretty straightforward article. It slides onto the centerlock mount on your hubs, leaving an interface to mount a six-bolt rotor. It includes a six-bolt washer, a lockring, and a circle clip to secure the conversion, and a standard Shimano lockring tool is all you need to install it. It's a home mechanic's job, but note that each kit only adapts one centerlock hub, so you'll need two for an entire bike.

Please note that this kit is not compatible with most 2-piece rotor designs. These rotors typically feature an anodized black center carrier that is bolted to the steel outer rotor, and they can create clearance issues when used with this kit. Stick to one-piece rotors for optimal compatibility.

My wife’s Felt all-road has Ultegra DBs with Avid 6-bolt rotors on Stan’s Grail hubs. So, this adapter will allow CL Shimano rotors? I’m new to DBs, so I want to get this right! Thanks!!!

An elegant solution for one-piece rotors

I bought this to convert my Shimano XT centerlock hubs and make them 6-bolt compatible since I already had 6-bolt rotors. This product is extremely easy to install, and they stay secure. It doesn't seem to significantly affect rotor location as I didn't have to adjust my caliper very much after installation. I used with standard, one-piece rotors without issue. As mentioned below, this will not likely work with two-piece rotors. The price is hard to beat, and shipping was quick. Thanks Backcountry!

Check Your Rotor First

I'm sure these would work perfectly fine for standard one-piece or other compatible rotors, however they are not compatible with my Sram Centerline two piece rotors. The adapter's flange face measures ~2.228" at the widest point. The rotors have a recessed mating face of ~2.175" so it isn't possible for the two to sit flush. Another thing to note: this adapter didn't quite work in the manner I hoped. I was looking for an adapter that kept the rotor bolts exposed, allowing the rotors to be swapped in the field easily with a T25 rather than lockring tool/wrench. That's not how this adapter works. I don't think what I'm specifically looking for exists so I'll probably need to find an alternate solution like a pocket lockring remover tool.


I have a Scott genius with centerlock Shimano SLX brakes. I'm planning to put a new rear wheel, likely the Race Face Aeffect SL 24mm, which is a 6-bolt. Will this converter enable me to use my existing rotors on the new rear wheel?


Can I use a clark rotor with a shimano centerlock to 6 bolt adapter

Problem solved

Have 6 bolt rotors and need them to be centerlock? This will do the trick for you at a cost effective price.


Will this work for putting it on shimano saint hubs to advid brakes


Related to the previous review-- are there any centerlock to 6-bolt adapters that work with RT-86 and RT-76 (w/ aluminum spiders)?

I would also like to acquire this information. Have you found a solution?

User Error? or Manufacturer Error?

Broke a wheel, so I ended up getting a new wheelset with centerlock hubs. I thought I'd save some money and try these. I couldn't get this thing to work on my XT icetech rotors. The rotor alignment was all off once i put my wheels back on. I tried every assembly variation I could come up with. Spend the extra $ and just upgrade to centerlock rotors.

Its not an error. These adapters do not work with aluminum spiders found on higher-end rotors. CC should really have not left that out of the product description: "Due to the aluminum spider SM-RTAD10 & SM-RTAD05 cannot be used with Shimano RT86 or RT76 6-bolt rotors"

no user error - i had a bolt head round out from this kit. i was using a Bikehand torque wrench, and it was the last of 12 needed to secure 6-bolt rotors to a CLD hub front and rear. i knew i was screwed and when the lock ring rubbed on the fork, i prayed i could remove the rotors and not lose the entire wheel in the process. i am a lifelong Shimano fan but with TRP rotors and brakes on Shimano hubs, this kit was a bust for me. and since the 160 6-bolt rotor is also permanently affixed to the kits washer and shim, i lose out on being able to return the kit or sell the extra 160mm rotor. all around loss of $$$ than had i just sucked it up an got lock rings and CLD rotors in the first place as my instincts were telling me to do.
