I was just saying how much better they are than any other fork for the price! I can get one again for $270CAD brand new. Then there's the RCT for 900, or Fox for like 1200
They are very good forks. Looks like they've broken from being ridden whilst over-tightened. So far every pair of broken circuses I've seen have died of the same cause. You should follow the manufacturers recommended torque settings rather that just tighten it as far as you can.
I definitely didn't tighten as far as I can. I put the Allen key in so that the long part was in the bolt, and I'd make it snug from twisting on the little tiny part on the Allen key
