Aluminum alloy chainring bolt set
Color: SILVER ANODIZED
Size: Single speed (BMX)
These will tighten down to 6mm (so the thickness of your crank spider or power disc plus chainring must be thicker than 6mm. The thinnest combination in our Chop Saw brand is 6mm. If you want to run a steel spider, these will not definitely not tighten down).
