Nothing mate, just PM me your address, it is what I'd call functional, the clamp is nice but the bit that connects to the caliper will need a little polishing
I hope I can use less than 42 teeth because I have two 36t CNC rings and Slalom MRP's ! I'm actually mocking this part up on my floor over last cpl weeks, I was gonna try n run a front mech but I think the chain height would be an issue with even 26t small ring (would hit swingarm, chain too low) but my bike came with a 36 or 38t ring and bash, visually it looked ok and turned. It all bolts up ok anyway. I do have the AC 42t ring but my MRP's are too small for it (no sale sorry!)
