These spiders also accept the SRAM X-SYNC 104bcd 12 speed Eagle chainrings as these have the 88mm ID fitting and NOT 90mm as usual. These chainrings are available in sizes 32, 34, 36 and 38t as well.

IMPORTANT - The interface on ALL Middleburn spiders is the same and so you can fit ANY spider onto any cranks BUT fitting X Type spiders onto SQ Taper Cranks or vice versa will have an effect on the chain line and change it from it's designed specification. If you are doubt what spider can be used on which type of cranks please email us and we can help.
