What began as a company the produced sails in the 1970’s, quickly evolved into a world premier manufacturer of windsurfing equipment – with a strong emphasis on composite materials. Not surprisingly, the Hong Kong based, Neil Pryde, entered into the bicycle realm in 2011 – producing some very impressive road bikes – across a range of reasonable price points. In fact, for 2013, they became the bike of choice for the UnitedHealthcare racing Team. Here’s glimpse of their road bike line-up for 2014.
BURAsl
A number of changes were made to the BURAsl to further decrease the frame weight. The carbon lay-up was re-engineered to utilize longer strips of carbon pre-preg instead of shorter pieces, minimizing the number of overlapping layers.
Designed as the evolution of the award winning DIABLO, the BURAsl was performance engineered to achieve the highest stiffness to weight ratio, ensuring the most efficient and direct power transfer.
BURAsl’s front triangle is made from NEILPRYDE C6.9 uni-directional carbon fiber and incorporates our proprietary Exoskeleton technology. External carbon fiber ribs integrated in the key joints of the monocoque front triangle ensure the BURAsl frame responds immediately each time you step on the power.
Carbon fiber front and rear drop outs, a Press Fit 30 bottom bracket and carbon headset cups further reduce the frame weight without sacrificing durability or performance.
That is it: bare minimum weight and maximum performance. The only thing we piled on was the unflinching NEILPRYDE attitude, which weighs nothing.
BURAsl’s front triangle is made from NEILPRYDE C6.9 uni-directional carbon fiber, the highest modulus suitable for bikes resulting in super-light, 710g frame weight with no compromises on stiffness.
Deep section chainstay combined with our One-piece Stays construction result in decreased weight, increased stiffness in the rear triangle and improved power transfer
A high-tolerance control of wall thickness in bottom bracket and head tube is possible through use of PU mandrel and internal layer of 3k carbon fiber
First developed for the DIABLO, external carbon fiber ribs are integrated into the head tube and seat tube joints increasing lateral stiffness and torsional rigidity of the monocoque front triangle.

ZEPHYR
Introducing the all-new ZEPHYR road bike. Designed for the strongest of racers yet compliant enough for sportive cyclists, the ZEPHYR comes with a geometry suitable for the longest of races.
The ZEPHYR shares the same DNA as the rest of the NEILPRYDE range – bikes designed to be raced at the highest level. The front triangle is made from C6.7 carbon fiber and incorporates many of the same features developed for the race proven ALIZE and BURAsl.
OTP Comfort technology was first introduced in the BURAsl, and was the key factor that allowed the BURAsl to achieve the necessary vertical compliance without sacrificing stiffness. The concept has been further developed in the ZEPHYR with the unique tube profiles utilized in the seat stays and fork. Subtle shaping of the seat stays running into the seat tube, combined with specific carbon layup, increases the damping effect of the rear triangle. The curved fork blades absorb vibrations from uneven roads in order to maintain comfort during the longest of races and stability under braking and cornering.
Vertical compliance, stable handling and efficient power transfer are key factors whether you are a seasoned pro or a weekend warrior. The ZEPHYR raises the enjoyment of cycling for riders of all levels.
Tube shapes form the important base for the weight and mechanical properties of a frame. The combination of carbon fibers, modifications to alignment and the application of variable wall thickness increase vertical compliance while maintaining high levels of lateral and torsional stiffness.
Curved seat stays running into the seat tube increase vertical compliance
Variable carbon fiber thickness aids tube flexion
Cantilevered drop-out for vertical compliance
Curved fork blades absorb vibrations for increased comfort while maintaining stability when braking and cornering
RACE PERFORMANCE
Designed to be raced at pro level and utilizing C6.7 carbon fiber, PU Molding and One-piece Staystechnology means no power is lost during the pedal stroke and makes the ZEPHYR responsive enough for the most powerful of sprinters.

ALIZE design reflects the balance between elegant engineering and insane speed. It draws on NEILPRYDE’s 40 years of experience working with the wind and 25 years of carbon fiber expertise.
BMW Group DesignworksUSA’s computational fluid dynamics analysis and NEILPRYDE’s optimised tube profile techniques combined to minimise drag while maintaining stiffness and the assured handling you expect from a pro-level race bike. Wider tube profiles have been incorporated to delay flow separation and maintain torsional rigidity. The unique down tube changes shape to manage both laminar and turbulent airflow, and the extended Kamm-tail creates an aerodynamic, lightweight and stiff bottom bracket.
The optional 78°sl TT/Tri seat post transforms the ALIZE from a traditional road geometry to a triathlon or time trial specific set up. Perfect, if you’re looking for one bike that can do it all.
The new ALIZE has been further upgraded:
All this makes the ALIZE the perfect aero race bike if you like to breakaway from the peloton, tackle the longest of training rides or throw in the occasional triathlon… just because you can.
Traditional 3:1 airfoil in head tube to manage relatively smooth, laminar airflow.
Airfoil shape combining a blunt leading edge with a longer trailing edge cleans up the turbulent airflow coming from the fork and rotating front wheel.
Kammtail airfoil, with a wide and truncated tail, combined with a narrower seat tube creates an extended virtual airfoil and results in a more aerodynamic and stiffer bottom bracket.
Traditional kammtail airfoil shields rear wheel.
Utilizing NEILPRYDE’s One-piece Staysdesign and PU Molding process enabled the aerodynamic ALIZE to be further developed into the ultimate race bike.
PU Molding in head tube and bottom bracket shell ensure high tolerance control of wall thickness.
1-1/8 upper and 1-1/2 lower headset bearings.
NEILPRYDE Aeroblade road or optional 78o SL TT/Tri seat post.
Specific carbon lay-up in the rear triangle ensures a more compliant ride than traditional aero road bikes.
Carbon fiber headset cups and front/rear dropouts.
Three bolt bottle mount for reduced drag with lower position when using one bottle.
BAYAMO
The razor-sharp triathlon bike.
An aerodynamic, responsive and comfortable racing machine.
Designed in collaboration with BMW Group DesignworksUSA using sophisticated Computational Fluid Dynamics simulations, extensive wind tunnel testing and input from the UnitedHealthcare Pro Cycling Team’s TT specialists, BAYAMO is fast and trim, meeting the highest standards for aerodynamics, stiffness and comfort.
BAYAMO features NEILPRYDE’s unique Kamm-tail airfoil. While a traditional airfoil profile performs well at narrow yaw angles, it is inefficient at the wider yaw angles of up to 30° experienced by a rider during time trials and triathlons. The narrow profile and long trailing edge of a traditional airfoil are also structurally unsuitable for withstanding the dynamic forces of a powerful rider.
The profile of the NEILPRYDE Kamm-tail airfoil is 10% wider than those found on other leading time trial bikes. This has the dual benefit of delaying flow separation, further reducing drag, and providing an inherent shape that is up to 60% stiffer than traditional airfoils.
The result is a frame that balances aerodynamic performance with the stiffness to weight ratios necessary for a professional level race machine.
ULTIMATE AERODYNAMIC PERFORMANCE
Deep section head tube for improved aerodynamics and management of laminar airflow, combined with the subtle integration of the Kamm-tail airfoil in the down tube to manage turbulent airflow from the rotating front wheel.
Chamfered trailing edge of the Kamm-tail airfoil in the down tube dramatically improves aerodynamics and decreases drag at wider wind angles.
The Kamm-tail is seamlessly integrated into the trailing edges of the fork, seat tube and seat stays, further increasing stiffness-to-weight ratio and improving aerodynamics
Down tube is 10% wider than those found on other leading time trial bikes, and results in an inherent shape that is up to 60% stiffer than traditional airfoils.
PU Molding in head tube and bottom bracket shell ensures high tolerance control of wall thickness.
