## Overview

The Shimano CENTERLOCK to 6-Bolt Mount Adapter (SM-RTAD05) is a high-quality steel conversion plate designed to fit Centerlock hubs and enable mounting of 6-bolt rotors. It includes all necessary hardware with pre-applied thread locker for secure installation using standard Shimano tools. Ideal for cyclists seeking durable, reliable rotor compatibility upgrades, this adapter is backed by Shimano’s 2-year warranty and is optimized for one-piece rotors to avoid clearance issues.

## Description

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.

Review: It's STEEL and it WORKS! - I needed a new Centerlock adapter to replace an aluminum Bontrager model that I managed to wear out the threads after replacing probably my third rotor (I commute 20-40 miles a day). They did not strip due to cross threading, at least that I could tell, but just from too many removal/install cycles using a calibrated torque wrench (for the final torque step after hand threading). Before I hit the 40nM point, the resistance just went from slight to nothing. Removal saw little bits of thread come out. I was worried they were bits of the Shimano dynamo hub, but they were not magnetic and definitely felt aluminum. That preface out the way, the Shimano Centerlock adapter works fine. It comes with six bolts, with thread locker already applied, and ready to go. Installing it was a cinch using a torque wrench in the usual manner. The locknut portion was easy to start the install by hand, but you do need the appropriate adapter to complete the tightening. If I am wrong, I will correct it, but I am fairly certain I used a Park Tool BBT-49, now the 49.2 model Park Tool Bottom Bracket Tool - BBT-49.2 Black, 39mm , bottom bracket tool along with a 3/8" torque wrench such as this Tekton, which I also use TEKTON 24330 3/8-Inch Drive Click Torque Wrench (10-80 ft.-lb./13.6-108.5 Nm) . The big selling point is that it is steel, so I expect no issues with thread damage. If you need a new adapter, I highly recommend this one, a genuine Shimano piece.
Review: Shimano makes quality parts that just work. - Shimano never lets me down. I found a great deal on new rims for my gravel bike, but had to adapt them to 6 bolt configuration. These worked perfectly and they were easy to install. I now have upgraded rims and better tires on my Giant gravel bike. These are a great value for the money and allow you to adapt various rim brands.

### ⭐⭐⭐⭐⭐ It's STEEL and it WORKS!
*by E***E on July 14, 2018*

I needed a new Centerlock adapter to replace an aluminum Bontrager model that I managed to wear out the threads after replacing probably my third rotor (I commute 20-40 miles a day). They did not strip due to cross threading, at least that I could tell, but just from too many removal/install cycles using a calibrated torque wrench (for the final torque step after hand threading).

### ⭐⭐⭐⭐⭐ Works with 223mm rotors on Orbea E-bike w/modification
*by J***S on March 23, 2023*

As others have mentioned; this is a good adapter and needs to go on one way, even though it looks like it flips both ways. With this adapter, I went from using a 203mm Shimano (XT MT800, ice tech) up to a TRP 223mm rotor (the TRP 223mm 2.3mm thick rotor does not come in center lock). The MT800 is a fantastic rotor, but since I have been riding more trails with extended steep descents + 50lb e-bike, I needed an even more insane rotor. Out of the box install positioned the rotor and speed sensor in contact with the frame (see photos). I lapped/wet sanded and removed just a hair over 1mm of material from the 6-bolt adapter, sanding the side that contacts the rotor (see photo). This solved my problem (before and after photos)! Other than that this works awesome!
