Farr-ST Supa-X Stem Jordan Callum Signature Series


The 2nd part of our SUPA-X story.

With arguably the strongest and stiffest handlebar on the market, we have designed a stem that not only compliments the handlebar but raises the stiffness bar even higher!

Featuring a wider clamping area than any other BMX stem currently on the market, the new SUPA-X brings next level stiffness and efficiency to your cockpit.

The 70mm width at the handlebar is significantly wider and features a unique Moto-Style 1pc Top Clamp to complete the look!

Available in 3 extensions – 45, 50, 55mm.

The PRO’s now have a Bar + Stem Combo worthy of their maximum efforts out the gate and on the track!

  • CNC Machined Alloy
