Wheelset Gravel HP64X6L 6-bolt Heuer

Wheelset Gravel HP64X6L 6-bolt Heuer

The Gravel HP64X6L Carbon wheelset was developed for demanding use on unpaved paths and trails. It is aimed at gravel and cross riders who value low weight, high stability and efficient power transmission.

At the heart of the wheelset is the stable and stiff Heuer hub set with smooth-running industrial bearings: Heuer X64V and Heuer X64. The wheel hubs are characterized by the precision of the manufactured bearing seats and the stable axles.

Our aim is to save weight, but not in the areas that are necessary for stability and durability.
Overall, this is the "easiest" way to save watts.

For this purpose, we use CFRP rims with particularly high-quality carbon fibers, which increases the fiber volume proportion and reduces the rotating mass of the wheels due to the lower use of resin.

In the HP version, we consistently focus on maximum lightweight construction. We achieve this through:

• Extremely lightweight SL rim construction (40 g lighter per rim compared to EQ64X6L!)
• 24 spokes for optimum balance of stability and weight
• Aluminum axle in the rear wheel for additional weight advantage
• Maximum system weight: 105 kg

The following options are available on request:

• Setup for 5 mm quick release instead of thru axle
• Colored hubs available on request, partly in stock
• Tubular rim instead of tubeless ready
• Steel axle in the rear wheel for more stability with low additional weight (standard in the EQ version)
• Smooth-running bearing with adjacent seal

Performance features:

1. Rims:
   • 30 mm rim height for optimum balance between smooth running and lateral stiffness
   • High proportion of high-quality carbon fibers for reduced rotating mass
2. Hubs:
   • Specially developed gravel hub X64
   • Inclined flanges to minimize the spoke load
   • Precise CNC production in Aichwald
   • Adjustable bearing play for silky smooth running
3. Freewheel options:
   • Support for various standards (Shimano, SRAM, Campagnolo)
   • Selectable freewheel angles: 12° (30 clicks), 6° (60 clicks), 3° (120 clicks)
   • E-bike version with reinforced freewheel available
4. Wheel design:
   • Tubeless Ready for improved grip and riding comfort
   • Asymmetrical rim design (12 spokes, double-crossed)
     for optimized lateral stiffness and uniform spoke tension

The Gravel HP64X6L Carbon wheelset combines technical precision with high load capacity to meet the requirements of demanding gravel and cross tracks.

Note: The hubs and components are available in various standard anodized colors. Slight color variations may occur due to the alloy components of the aluminum.
