Have just bought a used Wicked 650b frame and can’t seem to find a few bits of info I need online. Basically just want to know if it can safely take a 203mm rear disc brake and what size disc the post mount on the frame fits without an adapter on it? Also I assume it’s a 30.9mm seatpost?

Hang on, I have one in the shed – let me check it

Is it the 2014 650b?

If so, comes with 200mm rotors and yes 30.9 seatpost

YT Wicked

30.9 with 34.9 clamp
135×12 rear end
215×63 shock giving 158mm travel
I ran a 203 rotor but had to use a combination of washers to get the desired fit…i went back to a 180 as its plenty in all honesty and you dont need an adapter.
From what i found..the easiest waybto.run 200 was using avid brakes and their adapters

Should have said it’s a 2013 afaik. Thanks for the info 🙂 I’ll prob just get a 180 rotor if it means faffing about with washers to get it to fit right.

As above, measured the one in the shed and it’s 30.9 (30.95 on my calipers, tolderance fans)

Rear rotor is 200mm Avid with XO calipers using a +20PM Adapter and a bunch of wshers
