## Overview

Trusted by thousands with a 4.6-star rating and backed by Shimano’s 2-year warranty, this adapter ensures reliable braking performance for daily commuters and enthusiasts alike.

## 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: Great adapters - Work great and don't come loose.

Work great and don't come loose.

### ⭐⭐⭐⭐⭐ Shimano makes quality parts that just work.
*by A***R on June 27, 2025*

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.
