    New chainring doesn't pair with old chain

    So i just replaced my cranks and chainring, going from a Truvativ Touro 48t chainring to a Sugino Messenger RD 44t chainring - the Sugino is 130mm and I suspect the Truvativ was 144 or something like that. My problem is that my chain does not settle into the new chain ring - it fits into a couple notches but then starts to ride out of them.

    From what I can gather all modern chains are the same, but this has really got me confused. The Sugino ring is for 1/8x1/2 chains, so I can;t figure it out. What gives?

    Thanks in advance.

    Your old chain is 3/32". You need to replace it with a 1/8" chain as your new chainring is 1/8" thick. Track or BMX chain is what you need.

    Does it ride out in this manner?

    It's really nothing special. It's an old Litespeed Classic single speed conversion.
