“So long, on the track you’re practically riding in your own slipstream”

The longest of longboi’s, this sprint stem extends your reach out for a more aerodynamic position to get the most out of the UCI geometry regulations.

The Elite Longboi is the stiffest stem we have tested to date! The stems have exceeded 2x the fatigue and static overload ISO requirements for racing bicycle steering components.

Designed in collaboration with Cycling New Zealand for Tokyo Olympics.

Specifications:

• UCI certified for competition use
• JKA certified for Japanese's Keirin Racing 
• ISO 4210-5:2023 certified (tested to 2x the ISO requirements)
• 120mm to 200mm lengths
• +/-6, +/-12 or +/-16 degree angle options
• Reversible mounting capability (angled up or downward)
• Aero design developed using CFD software
• Rear mounted stem cap bolts for reduced aerodynamic drag
  
• Titanium hardware for weight reduction
• Low profile steerer tube clamp for greater integration with notched headtube framesets
• Material: Hard anodised 7075-T6 aluminium
• Weight: 150mm/6deg - 250g
• Steerer diameter: 1-1/8th
• Bar clamp diameter: 31.8mm
• Bar clamp width: 48mm
• Steerer clamp stock height: 32mm

Notes:

• Recommended to use a long hex driver to torque up the reverse facing screws
• Replacement screws are available here
• 5Nm Fastening Torque (Ensure use of a torque wrench)
• Recommended to use copper grease on screw threads (grease not included)

Geometry:

Traditional stem measurements like length and angle don’t easily show you where the stem actually places your handlebar. This calculator uses your bike’s head tube angle to determine the exact reach and stack coordinates of the Elite Longboi Stem - giving you precise data to optimise your fit.
