400ex Biopace chainset in good condition. Outer 52t chainring only, fitted with short chainring bolts. Intentionally converted from the original two speed setup a while back. In good overall condition, chainring runs absolutely fine, teeth in good nick.
Will double check crank length but I think it’s 170mm.
PS Just in case you’re not sure, you don’t have to stick with the biopace ring, can replace with any 130bcd ring.
PM if interested, can collect from Tower Bridge or Highgate Road
