5DEV 8 Bolt Spider 104 BCD BMX

The 5DEV 8 Bolt Spider 104 BCD BMX is a CNC machined 7075 aluminum crank spider that lets a SRAM 8-bolt crank run a 104 BCD chainring, the common BMX bolt pattern.

A crank spider is the star-shaped piece that bolts to the crank arm and gives the chainring something to mount to. This one fits cranks with the SRAM 8-bolt interface, which covers 5DEV's RGXC Titanium Cranks, the 5DEV Cam Zink Signature Freeride Crank + Chainring and the 5DEV Titanium MTB Cranks, all of which are suitable for BMX use. With the spider fitted, those cranks take any 104 BCD BMX chainring.
