Going from 6-bolt to centre-lock rotors

Hi all,

My rear wheel died recently and the LBS said given the cheap hub and labour I might as well replace, so I’m buying DT Swiss 1900. Thing is, I can’t find 6-bolt anywhere — just centre-lock. So, do I need any additional tools or anything like that? I’m gonna order the wheel and a new disc, so just checking I can fit it myself.

Cheers,

FM

You can get an adaptor to fit 6-bolt rotors to centre-lock hubs, although if you’ve a new rotor en-route that’s probably not important.

Otherwise, it’s a trad BB tool to tighten the lockring on the rotor. Makes fitting rotors a lot quicker!

They should come with 6-bolt adaptors so will fit either kind of rotor.

You can buy adapters to fit 6 bolt rotors to a Centerlock hub if you want to use your existing rotors. You will need to correct tool to tighten and remove the Centerlock fittings, AFAIK, there are at least two different ones.

No, the DT ones go on with a BB tool.

You can also get 6-bolt adapters if your disks aren’t worn.

The adaptors cost almost as much as a rotor.

What should I get external or internal splined for DT Swiss wheels??

Does it make a difference? Oh bicycle “standards”!

If your new wheel is retail boxed then it should come with a 6 bolt adaptor – they certainly used to.

The last dt swiss wheels I bought came with a 6 bolt adapter, if using centrelock they’re fitted with either a cassette or BB tool depending on the  hub

I’m pretty sure it’s only wheel set pairs that come with all the accessories. Individual wheels I don’t think will come with adapters, expecially “lower” spec ones.

Just got some DT Swiss wheels, bought as single part numbers. Centre lock fittings and six bolt adapters in both boxes, got Shimano and Sram freehubs too!

What’s the big issue with having Centrelock? I had to replace a wheel on my gravel/commuter bike recently, have always had 6 bolt, but Merlin had a CL wheel for a bargain price. So now I’ve got one of each. Just need a cassette lockring tool to fit it. Then forget it.

No, the DT ones go on with a BB tool.

Rotors on my G1800s (370 hub) go on with a cassette lockring tool. I’ve no idea about higher level hubs.

It’s not about level, it’s usually about axle size / application. Boost and MTB wheels tend to use the BB tool on the outside of the lockring; gravel / 142 wheels tend to use the cassette tool on the inside. Larger axles get the larger lockring area, hence the different tool.
