Designed by former World Champion, Olympic silver medalist and G.O.A.T contender Sam Willoughby, the Siren Pro offers BMX racers unparalleled performance on any track. Lightweight and fast-rolling, the 120 TPI, tubeless-ready tire rails turns, smooths out technical straightaways, and provides insane grip on the gate and out of corners.
- Supple 120 TPI shaped casing
- Center slick design for gaining maximum speed
- Super-narrow gaps in the center tread grip the start gate without flexing
- Wider gaps on the shoulder provide max grip when cornering
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
