MIDDLEBURN RO1 SQ 110BCD SQUARE TAPER TYPE DOUBLE ROAD SPIDER

This Middleburn spider is compatible with the Middleburn RO1 Square Taper cranks which require a double 110 BCD chain ring set up. Do not use this spider on RO2 X Type cranks unless you are trying to achieve a specific chainline. If you are in doubt please contact us and we will help.

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

The chain line is a standard road of 44mm between the outer and inner chainring as standard.
