Hunt 40 Carbon Disc Wheelset Upgrade

Please note: This product is available as an upgrade for our Temple Road 1 & 2 complete bikes. This is not available to purchase as a standalone product.

New for 2024, the 40 Carbon Disc was built for riders looking to upgrade their experience with quicker acceleration and lower rotational weight on climbs. These wheels also benefit from the aerodynamic gains offered by a 40mm-deep, U-shaped carbon rim profile.

The 40 Carbon Disc is optimized for 25mm-35mm tyres for fast road riding and racing, increasingly popular all-road terrain, as well as gravel riding

KEY BENEFITS

• Reduced weight means the wheels accelerate faster and with less effort
• Deeper section are more aerodynamic (compared to alloy wheels) which means they maintain speed with less effort
• Great ride quality
• Superb looks

KEY SPECS

• 1433g, a 102g saving over the 4 Season Pro (standard spec as of July 2024), or a 247g saving over the 4 Season All-Road (previous spec).
• Great ride quality thanks to compliant low-temperature resin
• 40mm deep rims which look amazing
• 22mm internal width, ideal for 25-35mm tyres
• Aerodynamic benefits of a 40mm deep, U-shaped rim
• 24 spokes front and 24 spokes rear

RIMS

Unidirectional carbon fibre rim construction, with 3k reinforcement at spoke holes for greater durability. The layup is comprised primarily of Toray T700 fibres which offer high impact resistance and flexibility. V:Absorb resin reduces vibration and massively improves impact resistance. Disc brake rims are not required to handle the high temperatures induced by prolonged rim braking. Hunt have made the most of this and used a new resin which cures at a lower temperature. Lower temperature resins are less brittle meaning they have greater resistance to impacts and dampen vibration more effectively.

HUBS

The HUNT H_Ratchet 36T SGL hubset provides a 10-degree engagement angle with improved durability, offering increased engagement surface area while using less shell materials relative to our race-proven pawl-based systems.

SPOKES

Hand-built with top-of-the-range, reinforced Pillar PSR triple butted J-bend spokes for durability. Triple butted spokes reduce weight and provide greater elasticity to maintain optimal tension and resist fatigue, with an increased 2.2mm diameter at the spoke head, providing more material in this high stress area, all leading to excellent durability and long spoke service life.

BEARINGS

Precision stainless steel cartridge bearings with waterproof grease specially selected for the worst weather.

TECHNOLOGY

The 40mm deep, 30mm-wide carbon profile provides stable and predictable handling while reducing drag across multiple wind yaw-angles. The wider 22mm internal rim bed opens out your tyre profile providing exceptional vibration reduction, improved cornering traction and low rolling-resistance, especially when ridden at lower pressures with modern-width tubeless tyres.  

The HUNT team have paired the wide hooked rim with new H_Ratchet 36T SGL hubs, offering a rapid 10-degree engagement angle, in a reliable, easy-to-service and long-lasting single-sided ratchet drive system. Increased engagement surface area improves power transfer and longevity of the hubs, while using less material compared to a spring-and-pawl system, resulting in a light but robust hub system designed and tested to cope with the torque demands of road or gravel drivetrains. Hand-built with top-of-the-range, easily serviceable Pillar PSR triple butted J-bend spokes and precision sealed cartridge bearings, this wheelset is ready to speed up your road, CX, or gravel rides.
