RACE BIKES SE Racing STR-1 Quadangle Pro BMX Race Bike-SE Blue

The SE Racing STR-1 Quadangle has finally arrived. It was only a matter of time for SE to recreate Stu Thomasen’s original bike, SE Racing STR-1 Quadangle. Stu won the Pro title in 1979 on his STR-1. This unique design with double down tubes wrapping underneath the bottom bracket shell and continuing around the looptail rear end and ending at the seat tube. Welcome to the vintage BMX world. The SE Racing STR-1 Quadangle is a true throwback to the good old days of Stu. Showcasing memories and riding dreams become a reality. As they say you can’t buy happiness, but you can buy a bike.
