Farr-ST Supa-X Stem 31.8 – Various Lengths Available

$150.00 AUD

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!

Note : this stem uses a ZERO GAP DESIGN for stem clamping at bolts 1 + 2. This design ( also known as Moto-Style ) increases contact area of the bar/stem interface but requires the correct assembly process to be followed – it is important that bolts 1 + 2 are correctly torqued to 10Nm FIRST and then only the front bolts – namely 3 and 4. The front bolts should NOT be tightened down so that the stem cap touches the body – there should be a 3~4mm gap in the front of the stem cap. ( where bolts 3 + 4 are located )
