Bringing this thread back from the dead. Well, after the machinist guy took my broken carbon halfpipe, now he won't answer my calls, and I've never heard from him since. So the other day I felt like tuning the factory lower pig iron. I got 6g off of it. Not bad, but a custom made part wold of been better. I could also grind more aluminum away, but I was trying to be conservative. I basically cut the extensions off where it cradles the rail, and I ground it smooth. I also ground out the inside of the half pipe too.
this got the whole post with hardware down to:
here is a close up of the new assembly. The original aluminum insert was starting to get worn. So I switched it out for the gold one shown, I harvested it from a broken KCNC seatpost collar. I had to drill the post out the next size bigger, but it works great, and I can now use the next size smaller bolt too. Went from a 5mm allen bolt to a 4mm.
Everything all together, The saddle weighs 133g, even know it says 125g on it. Damn fibbing Italians. I still want to see if I can get a machinist to make me one, or if I pick up another pig iron, I might go a little more radical with this one. I am sure I can get it down sub 15g
