Farr-ST Supa-X Bar + Supa-X Stem Combo

US $195.00


It’s no secret that the 31.8mm oversize standard is stiffer than the traditional 22.2mm used in the past.

With quite a few brands now offering 31.8 as their default option for adult riders, we wanted to take the concept even further.

Having already seen the strength and rigidity benefits of widening the clamping area with our HeadSpace range of stems for MTB, we knew there could be a performance benefit for BMXers.

Today’s PRO riders are putting their equipment to the test in ways not seen in the past. These demands coupled with modern riding styles and techniques mean that a stiff and precise front-end is not only essential but also beneficial for faster and more efficient lap times!

With our new SUPA-X handlebar we have taken the oversize and stiff concept to the next level …. Featuring the widest 31.8mm clamping area in the market these bars are ready to attack the track!

We worked with Jordan Callum on this concept and developed a Signature Model based on his preference for width, rise and sweep.

Featuring triple butted 4130 chromoly tubing coupled with our exclusive bending molds, these bars are unlike any others on the market.

Compatible with all 31.8mm stems … we do however suggest matching them to our SUPA-X stems, which are in the works, for the ultimate stiffness gains!

  • Triple butted 4130 Chromoly Tubing
  • Wider 31.8mm clamping area

  • Matte Black
  • Weight : 1011g


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 )
