Profile Spider BMX 5 Bolt 110 PCD

This is the bolt on single chainring spider for Profile Racing 3-piece race chromoly cranksets, in the 5 bolt 110mm BCD pattern. It uses a standard sprocket bolt and works on 19mm (.75 inch) bottom bracket axles only, so check your spindle size before ordering.

The chainring can be mounted on the inner or outer face of the spider, which gives you some room to sort your chainline. It works best with the Profile internal bearing Euro, American, Mid or Spanish bottom brackets. The 5 bolt version weighs 71g and comes in silver or black.
