Pair of vintage MKS Esquartz, I believe they are 102's and not the 107's. Overall in good shape, with good bearings. They will clean up nicely. I figured I'd offer them here before I put them on ebay. $25 +shipping, will also take trades. I'm looking for a vintage red BMX chainring, 40-44t 110 or 130bdc but open to trading for other parts too.
