General Information
I think this is the earliest 144 BCD version of the Edco Competition crankset. The later versions were, I believe, 130 BCD also posted on this database, that definitely had shorter spider arms than this first version. This particular set also does not have the "Made in Switzerland" marking under the "Competition" label on the drive arm, but has it on the left non-drive arm. Chainrings look very much like they were made by Stronglight, but does not have they usual "S" engraved on them. I suspect that Stronglight was a supplier to Edco back then, just as Simplex was. The dust caps are also very similar to what is used on some mid 80's Stronglight cranks, specifically the Delta. Crank weight is surprisingly not that light compared to other cranks. Shape is not as unique as when it first came out as Campagnolo came out with cranks that look very similar. But proptions on this one is still very pleasing after over 30 years.
