Just brought a brand spanking new red middleburn chainring the granny ring, well I say just had it a couple of weeks now went up tom my ma and pa's to go and fit it to find its the wrong bolt size :evil: I know I should of checked but always get confused and wasn't sure if my crank is compact or non compact. Anyway the bolt hole spacing is way to big so am I guessing my crank is compact?, if so what size bolt circle is that or whatever you call it. Guess I'm just gonna have to sell it on, gutted as it is in mint condition aswell.
