MIDDLEBURN RO1 SQ 110/58 BCD INCY SQUARE TAPER TYPE DOUBLE ROAD SPIDER

This Middleburn spider is compatible with the Middleburn RO1 Square Taper cranks which require a double chainring set up with a 110 BCD outer and 58 BCD inner.

Middleburn 5 arm 110 and 58 BCD are machined from 7075 T6 aluminium for maximum strength.
