The Purpose _

<h1>Sprint SL hubs</h1><i>All-new Sprint SL hubs featuring the same reliable engagement at a lower weight package. The hub shell is 6066 series alloy, offering a greater strength-to-weight ratio than lower 6000 series alloys. Large 15mm diameter hub axles for climbing and out-of-saddle sprinting responsiveness. Circular dropout interface steps ensure a secure fitment. </i>

The Purpose _

For riders competing in disciplines where absolute aerodynamic efficiency is critical, the engineering team at HUNT Bike Wheels saw the potential for wider, front and rear-specific rim profiles to provide considerable time savings while offering improved stability in crosswinds. Stability and predictable handling characteristics allow the rider to maintain a low, aerodynamic position on the bike despite changing wind conditions.

KEY FEATURES_

Aerodynamicist Rims

Aerodynamicist rim profile, exclusively engineered and wind tunnel tested by HUNT's in-house engineering team, featuring a hooked and ETRTO-compliant tubeless-ready rim, designed for tubeless tyre compatibility.

<h1>Spokes</h1><i>We chose the top-of-the-range Pillar Spoke Re-enforcement PSR XTRA models. These butted blade aero spokes are lighter but also provide a greater degree of elasticity to maintain tensions longer and add fatigue resistance. PSR spokes feature the 2.2 width at the spoke head providing more material in this high stress area. The nipples come with a hex head so you can achieve precise tensioning. Combining these components well is key which is why all HUNT wheels are hand-built.</i>

CeramicSpeed Bearings 

CeramicSpeed bearings are renowned for their low rolling resistance, and are chosen by the top international athletes and teams. HUNT and CeramicSpeed partnered to launch the LIMITLESS project, and have been creating class-leading wheel systems since.

Wind Tunnel Tested

Developed by HUNT's in-house engineering team, with years in the wind tunnel spent testing every last detail. We've left no stone unturned in designing this wheelset from the ground up to be very fastest in the world within its class.

Sprint SL Hubs

Light, reliable, race-winning, and easy-to-service. Sprint SL hubs feature a 48T heat treated stainless steel ratchet ring combined with 3mulit-point pawls. The system delivers a fast 7.5°engagement angle and proven durability.

TECHNOLOGY _

As shown in the graphs, the HUNT 8387 Aerodynamicist Carbon Disc wheelset produces exceptionally low drag values when compared to numerous leading relevant competitors with both 25mm and 28mm tyres (see white paper for full tested competitive set). The DT Swiss Dicut 80F / 80R produced the lowest aerodynamic drag from the competitor tested and became the benchmark competitor for further testing.

The 8387 Aerodynamicist Carbon Disc provides an advantage over most competitors when it comes to all out speed. When combined with a 25mm tyre, the HUNT 8387 Aerodynamicist Carbon Disc wheelset follows the leading DT Swiss Dicut 80mm Wheelset (1777g) by 0.17W according to the Mavic Std WAD (Wind Averaged Drag), while offering a stable steering moment profile resulting in predictable handling. However, when simulating the performance considering the asymmetric wind conditions at KONA (World triathlon Championships), the HUNT 8387 Aerodynamicist is the leading performer in the wheelset class tested. After extensive testing, a 25mm tyre proved to be the aerodynamically superior setup. The 8387 Aerodynamicist is still a very competitive wheelset when combined with the 28mm tyre, with maximum differences of 0.34 Watts from the 25mm tyre option.

Tyres Info
HUNT recommends a 25-28mm tyre for best performance, tyre widths between 22mm and 47mm are also safe to use.   Note: best performance is usually gained by using tyre pressures lower than the maximum, you can see our blog post about this, read here.  Tubeless-ready for lower weight and rolling resistance.  You must not exceed the maximum tyre pressure limits set out in the table below or the maximum limit set by your tyre manufacturer if this is lower.

HIGH SPECIFICATION COMPONENTS _
CERAMICSPEED

CeramicSpeed's world-renowned, low-friction bearings. With CeramicSpeed bearings in your hubs, tests show that you will save between 6–9 watts, compared to using standard bearings. As chosen by top athletes and teams around the world.
AERODYNAMICIST RIM PROFILE

Our Limitless research and extensive wind tunnel tests found that wider rim profiles yield optimal aerodynamic benefits for riders. The more 'blunted' spoke bed area creates predictable airflow at a wider variety of wind yaw angles, with the air ‘hugging’ the rim as it passes across it, staying attached to the surface as long as possible before the point of separation. Traditional V-shaped rims tend to create turbulence in the form of stalls.
FREEHUB BODY

Featuring 3x treble-tooth pawls and a 48 tooth ratchet ring results in an impressively low 7.5-degree engagement angle, and excellent resistance to wear under heavy loads. The Sprint SL freehub has strong individual pawl springs which drive a consistent engagement. There is also a Steel Spline Insert re-enforcement on Shimano cassettes to provide excellent durability against cassette sprocket damage.
