STAY STRONG MOTION 4-Bolt Chainring
Unable to load pickup availability
Description
The Stay Strong Motion chainring is the brand's 4-bolt benchmark for BMX Race. Fully CNC-machined from solid 7075 aluminium — the strongest aerospace-grade alloy used for racing chainrings — it is 4 mm thick for stiffness that ensures power transfer without deformation off the start gate.
Its 104 mm BCD (BCD 104) makes it compatible with the vast majority of 4-arm cranksets and spiders on the market. Stay Strong logos are laser-engraved and the bolt seats are recessed, for a flush fit without protrusion.
Available here from 40 to 52 teeth, it covers both short gearing and high gears for Cruiser and Elite category bikes. Stay Strong was born from a support movement for rider Stephen Murray, initially as a charitable organisation before becoming a fully fledged component brand.
