4 arm spider from DMR Axe cranks but it will fit most cranks using the Sram direct mount interface (ie Praxis, Sram, DMR and more). The 'bed' for the crank arm is suited for the DMR AXE crank so we cannot guarantee that your crank arm will fit in this gap. However, the AXE is very chunky, so most other cranks should fit in this gap

The spider can have either 1 or 2 rings mounted to it. Bolts are included to mount the outer ring

Chainline is 49mm, the same as a non-Boost crankset

Please note our opening hours are 9am to 4.30pm, Monday to Friday. Any questions asked in the evening or at the weekend will be answered next working day.
