I built up my Cotic a few months ago. It was a slow process while I assembled bits and pieces. The final build ended up getting an Ohlins RXF 36 fork (overkill, but awesome), Industry9 Torch hubs with Nextie carbon rims, KS Ether 35mm carbon bar, TRP G-spec Quadium 4 pot brakes, XO cranks and an eagle drive train. Total build came in at 11.6kg which I thought was pretty good considering the frame and fork.
The bike is just so much fun to ride! Its way more forgiving and compliant than I was expecting it to be. I've had a few hardtails in my time, but never a steel one and I understand now why people love their steel bikes. Plus, with that beast of a fork I feel like I can just charge at and over anything in the trail.
I thought it would just be a fun 'every now and then' toy, but I've switched to using it exclusively which means that my wife has claimed my Anthem as her own
