Superstar Shimano Stepped Type Chainring Bolts for some 110BCD Asymmetric - ie R9000 R9100

4 BOLTS ONLY - for use with cranksets like Shimano Dura Ace R9000 where the single ring bolts directly into the outer ring and the bolt has a step in it. if your bolts do not have a step in it you need standard bolts HERE . This DOES NOT fit SRAM'S 4 bolt OE cranks (eg S350, Apex OE) which has stupid non-standard angles!

Superstar Components UK Made chainring bolts feature a high quality anodised and laser etched finish. They are manufactured from aerospace grade 7075 T651 aluminium ground barstock for ultimate strength and precision. With hex fittings on both ends fitting these couldn't be easier.
