Description

Tangent BMX chainrings are CNC cut from 6061-T6 aircraft grade aluminum in the USA to create a product that is precisely manufactured for your race rig's drivetrain. This is one component which needs to be 100% dependable. A dropped chain can end in not only a lost race, but can also leave you vulnerable to face planting the hill or track at high speed.

Features

4 bolt, 104mm BCD. Drilled for a 104mm four bolt crank, with a five bolt option offered as well.
36T to 50T available. Sizes run from 36 up to 50 tooth, so you can set the gearing your track calls for.
High tooth profile. The tall tooth profile is there for accuracy, because a dropped chain can cost more than the race.
CNC cut 6061-T6 alloy. Machined in Sacramento from 6061-T6 aircraft grade aluminium, 2.4mm thick at the chainring bolt.
Seven colours. Black, gun-metal, white, red, blue, gold and purple, for single, 7 or 8 speed chains.
