Which (Magura) brake adaptors do I need?

[Whatmot1]

Hello, I wondered if someone might be able to confirm which brake adaptors I'll need for my frame & forks to fit my Magura Marta SL's. The frame is a (2007) Voodoo Sobo with IS mounts and the fork is a pair of 2013 RS Sid's with post mounts. I want to fit 160mm rotors front and rear. Based on CRC's guide/website, I'm thinking for the rear I'll need a QM12 adaptor and for the front I was thinking I should be able to bolt the calliper straight to the fork. However, I've read the description for adapter QM20 (on Bike24's website) and it makes it sound like I'll need that? Can anyone shed any light on this? Ta muchly in advance

Rear is to post 160
eg item 221713510959

Assume your martas as post mount, earlier versions were is mounts

Yes qm12.

Why do you need magura adapter? You can buy shimano xtr version for much less.

Ok, that is what I thought. Do I need one for the front, or is it just simply a case of bolting the caliper straight to the forks?

And I don't necessarily need a Magura one but I live/work in Germany most of the time and I can get Magura adaptors over here as cheap as Shimano ones

Caliper direct to fork for 160mm disc.

Again, that's what I thought, thanks for confirming
