I'm currently using a 180mm rotor with 20mm adapter and want to upgrade to 220mm.

Anyone knows what adaptor I can use from 160 to 220mm?
I couldn't find any PM to PM 60mm from SRAM

Is the fork rated to use a 220mm rotor?

Unless you make your own adapter, the only way to do it would be to mount a 20mm adapter onto a 40mm adapter, if you do this check the pad alignment with the rotor, the pads should full contact with the rotor and never overhang it.

Just checked and Fox states "max 203mm rotors" are supported

Wondering how high is the risk to brake it...

I would use studs (not bolts) and be religious about torque if you do this.

Literally nothing is going to happen. Apart from having more brake.

Thanks twodownzero & cobba!

Still worried if risk is high of braking the mount in the fork, need to make up my mind if worthwhile...

Thanks anyway

It seems that there is one adapter from a company called Alligator,
Although in the picture it shows PM 160 -> 180mm:

Will call them tomorrow to check.

What's the fork and what sort of axle?

Why do you want a 220mm rotor?

Alligator don't mention this XQ37 adapter and there doesn't seem to be any photos of this adapter anywhere.

The only place that mentions that adapter is that Italian shop which also lists it on ebay.

I don't think this adapter exists.

 

[Guilherme]

Yeahhh so that...maybe I will just give up on the 220mm thing and just stick to a 200mm upgrade

Thanks folks!

I don't think there would be a problem with a 220mm rotor on that fork, I've got a old Manitou fork with a QR axle, it says it has a maximum rotor size of 210mm.

There's only 8.5mm difference in the radius of a 203mm rotor and a 220mm rotor.

It's up to you how you proceed, you've seen how you can fit a 220mm.

 

[fmendes]

I'm assuming you have tried the most common solutions, such as finned metallic pads, ICE rotors and 203 mm? These work fine for me, and I weigh 270 lb.

I'd not try to guess too much on the braking department, specially if you demand them too much.

Just in case anybody stumbles across this thread someday, I can confirm the XQ37 is real despite the prior lack of photographic evidence.

Nice confirmation! Will have to look to see if they have 160-223...

Galfer has a 160-223. I use it on a Rockshox Pike with their Wave disc, no Problems.

I couldn't find the Alligator version anywhere in the US. Here's a link to the Galfer SB003 +63mm adapter that I just ordered from their US site for a whopping $27. As a note I don't have Hope brakes. An adapter is an adapter as long as it clears my Saint caliper.
