Summary: High precision ground binding

The HI-TECH TRECH ST5 is a centerpiece of the rear train of chassis Birelart Charles Leclerc and Ricciardo Kart. This kit includes high-strength aluminum support (bearing) and precision bearing.

The specificity "St5" Designates a performance-oriented design, providing rigorous retaining from the tree while allowing maximum freedom of rotation. Format 50/40 (80mm outer diameter / 50mm interior) is the standard for 50 mm shafts on gearbox (kz) or high performance frames.


- Why choose the Hi-Tech St5 Birelart version?

  1. FREELINE QUALITY: Made by FREELINE (the official Birelart accessory brand), ensuring perfect compatibility with your chassis.

  2. ST5 Hi-Tech machining: The bearing is designed to optimize the flexion of the chassis. It allows a homogeneous distribution of constraints on the frame tubes.

  3. High speed rolling: Comes with a high quality ball bearing capable of supporting the intense shift loads.

  4. Anodizing Racing: Neat finish that protects against corrosion and facilitates cleaning after sessions in the rain.


💡 Michel's trick

"The axle landing is what makes your tree round or not! My Pro Council: When you ride your ST5 bearings, never squeeze the frames at the chassis before slipping your shaft of 50 mm inside. The trick: The tree serves as a centurizer. Once the tree is in place, tighten your beaux cross. If you squeeze the levels in empty, you risk creating a micro-constraint that will curl your bearing. And do not forget: a clean rolling is a fast turnover. If it scratches when you run the tree by hand, it's time to change! "


- Mounting & Maintenance Guide

  • Alignment: Check that the three bearings (for KZ chassis) are perfectly aligned to avoid brightening the back shaft.

  • Tightening of the needle: Once the tree is centered, tighten the bearings on the shaft (use light net brake) to prevent it from slipping laterally.

  • Cleaning: After each output, clean the outside of the bearing. Avoid the high pressure jet directly on the flanges of the bearing so as not to hunt the inner fat.
