I have just acquired a really tidy Middleburn RS 1 crankset, gorgeous condition aand machine work, but it's weird, as it has what looks like a CD spider i.e 94/58 BCD, the outer BCD is definitely 94, but the granny ring bcd is slightly smaller than 58 and a 58 will not fit.
The Spider looks original and thought it odd as the really early Middleburn chainsets were all 110 or 130 to the best of my knowledge, so what the 'ecks the bcd on the inner then? Anyone?
