To anyone who has a Cycle underground Chain-ring, Can you tell what Chain brand are you using? As I tried fitting a Wippermann Rotstern chain 1/2 X 1/8 onto a cycle underground 4mm Chain-ring. And chain catches on the sides of teeths when you rotate the chain-ring the chain is binding onto the chain ring teeth. I fitted my old KMC chain back on it works fine… but it’s a bit stretched and needs to be replaced, so I have ordered another KMC, see what happens. Thanks. ---

KMC kool: super smooth and quiet ---

KMC Superkool. The CU teeth are quite chunky. Check that your chainline is good. ---

The CU chainrings have a different tooth profile from the regular 1/8 chainrings from say, Sugino or Shimano. The tooth profile is not chamfered, but rather is square. This is a ‘good’ thing in that it’s possibly more durable (although I’m not sure if I believe this). On the downside this square profile might cause a few compatibility problems with chains like you mention. I use a Izumi nickel-coated 1/8 chain and it was noisy to begin with, but it’s pretty good now. ---

I’m running an izumi chain on mine and it’s fine. Bit of noise to begin with but gone after a few short rides. ---

+1 for the KMC Kool. The chunky angluar shaped links i gather are some sort of bmx thing, but out of the three chains i’ve been swapping between lately it’s by far the quietest. It does seem maybe a fraction wider than usual too which might help you out. ---

Thanks everyone for your replies, I thought it was just me that might be having this problem… I will be getting a new KMC Z510 chain today. Thanks again for the advise.
