NeilPryde launch Nazaré2 aero road bike with 920g frame

Slimmed down aero bike has 20% lower drag than predecessor, says NeilPryde

NeilPryde have launched the new Nazaré2 aero road bike with a claimed frame weight of just 920g. That’s superlight for an aero frame.

We first showed you the Nazaré2 a couple of days ago and now we have time to go into a bit more depth. It’s less a redesigned Nazaré than a completely new bike.

NeilPryde reckon that the Nazaré2 has up to 20% less drag than the existing Nazaré, called the Alize until Specialized’s lawyers got involved (it sounded too much like ‘Allez’, apparently).

The head tube is built to a 3:1 airfoil profile (the depth of the tube profile is three times the width) while the integrated fork runs into the lowered down tube. The idea there is to reduce the turbulence from the rotating front wheel.

The airfoil profile higher up the down tube combines a blunt leading edge with a trailing edge that tapers off gradually. NeilPryde say that this “cleans up the turbulent airflow coming from the fork and rotating front wheel”.

Closer to the bottom bracket the down tube profile is Kamm-tail, with a wide and truncated tail.

“Combined with a narrower seat tube [this] creates an extended virtual airfoil and results in a more aerodynamic and stiffer bottom bracket,” according to NeilPryde.

They have used Shimano direct mount brakes front and rear to reduce drag further. The front brake is mounted to the front of the fork while the rear brake is located behind the bottom bracket so there’s no need for a brake bridge between the seatstays.

The seatpost clamp is integrated. In other words, NeilPryde use a wedge system with all the gubbins inside the frame, including the tightening bolt. Most other aero road bikes are using similar systems these days to keep turbulence to a minimum.

Speaking of the seatpost, the Nazaré2 is compatible with a 78° Aeroblade SL time trial/triathlon post, although you’ll have to buy that separately. As the name suggests, this allows you steepen the seat angle up to 78°, pivoting you forward around the bottom bracket so that you can get a flat-backed riding position without the need for such an acute hip angle. In other words, it’ll help you get into a more aero position.

The cable routing is internal, except for the front brake cable, the entry point being at the junction of the top tube and the head tube. The battery for a Shimano Di2 electonic shift system lives inside the down tube.

NeilPryde have opted for a Press Fit BB86 bottom bracket. They say that this, combined with their proprietary PU molding process and one-piece stays, results in increased power transfer through the rear triangle.

The Nazaré2 is made from what NeilPryde call C6.9 ultra-high modulus carbon fibre. It’s carbon right down to the dropouts and the headset cups (1 1/8in upper, 1 1/2in lower).

Aero road bikes have been getting lighter and lighter recently, the Nazaré2 being the lightest we’ve heard of so far. That said, manufacturers’ published weights can sometimes be wishful thinking at best. We’d like to get the Nazaré2 on the road.cc Scales of Truth some time.

The Nazaré2 frameset, including Shimano Dura-Ace brake callipers), will set you back £2,699.

A complete bike built up with a Shimano Ultegra groupset and Fulcrum Racing 5 wheels is priced at £3,299

You can also pre-order a Shimano Dura-Ace model with Fulcrum Racing 3 wheels. That version is priced at £4,399.

Erm, not to be stupid guys but your article says NaVaré2 but the bike is clearly called the NaZaré as was the previous iteration of the frame!  39

My mistake. Sorted now, hopefully.
