Nicelly made although careful not to overtighten the bolts as they are quite a soft alloy and strip easily. Also works for adapting 140mm rear post mount to 160mm (what I'm using it for).

203 rotor adapter

Seems fine, does what it's supposed to. Seems better finished than the SRAM adapters.
Bike came with 180mm front

Bike came with 180mm front and 160mm back rotors and under some tracks I notice them feel off after they warmed up. Switching to 203mm on both made the lever force easier and no heat problem on long decents. Super happy!
