EB14: Neilpryde Nazaré 2 Aero Road Bike Drops Grams and Drag
The Neilpryde Nazaré 2 is the second generation of their aero road bike. Formerly the Alize, the Nazaré was renamed after a famous surf break off Portugal to avoid potential trademark concerns.
It’s a lightweight aero road bike that builds off their development work with BMW, further tweaked by their in house designer, Kevin Quan. He used to work with Cervelo and now runs his own design studio doing projects for Parlee and others.
They looked at each tube section to see how the air flowed over each one, then how it all flowed together. They showed me several CFD videos at the booth that illustrated the drag and turbulence and there were notable improvements around the headtube in particular. Beyond simple tube shape manipulation, there are a few clever touches elsewhere on the bike…
From the very front, it’s slipperier, getting a more aero fork. Behind it, the down tube was dropped to sit closer behind the front wheel. The top of the downtube uses a longer trailing edge and more blunt leading edge to move through turbulent air off the front wheel.
As the downtube moves toward the BB, it gets truncated at the rear and gets a more traditional air foil frontal profile. That pushes the air flow wider around the seat tube so there’s less forceful air flow hitting that tube.
That’s aided even further now that the seat tube is narrower. The seatstays are also aero shaped.
BB shell is dropped to shield the rear brake, which also keeps the cable tucked inside the frame all the way into the caliper. It’s one of the cleanest executions we’ve seen.
Build options for complete bikes only include mechanical groups, but pockets, covers and grooves within the frame allow for completely hidden cables and wires and batteries. That larger panel with two bolts covers an internal Di2 battery mounting position.
The frame is built from their 6.9 carbon, which is their higher end fiber. The BB shell is asymmetric, a design used across several of their bikes to maximize real estate for the chainstays and improve power transfer.
It’s available now, pricing and options are:
- Frameset with 9000 DM brakes $3,795
- DA9000 complete matte blue $6,095 fulcrum racing 3 carbon bar
- Ultegra mech bike gloss black $4,695 fulcrum racing 5 alloy bar
Frame weight is about 920g for a large, pretty good for an aero frame.
