EB14: Neilpryde Nazaré 2 Aero Road Bike Drops Grams and Drag

2015 Neilpryde Nazare 2 aero road bike

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.

Did you weigh it? Their Bora SL is very “optimisitcally” spec’ed.

looks like a bad copy of an old s3.

looks terribly ugly and not very aero. Downtube appears to have a “diamond” profile similar to the Kuota “aero-bricks” from years past.

Yeah, those cables near the stem are SO aero!

Gosh, I just can’t believe how manufacturers can ignore such things when publicly exposing their product to thousands of people…

Wow. Clean as can be at the BB, hideous execution at the headtube/stem.

At least they got rid of all the Target logos all over the bike. Though the one on the head tube still makes me think I should go get some discount toilet paper.

Anyone putting their rear brake under the BB is just doing it for appearances. It has almost no effect on drag. even Cervelo gave it up for the S5, not that I worship Cervelo or anything.

Yikes I actually feel bad for the bike after reading these comments. But I do get most of the points made, especially the cables near head tube. I would also add that the head tube area looks too boxy and tall. It seems companies are struggling with using the right geometry for target market while still making a good looking frame up front.

They could have done some things with this demo to make it look much better.

This is a really nice looking frame, but any frame that has the cables running on the top tube behind the stem make me sad.

Any builder who puts a brake at the bottom bracket should have a Howe case dropped on their heads!! It does nothing for aerodynamics and only makes life difficult for mechanics.

If a shop ever did a cable job on my bike that horrible I would never go back. Can’t believe NP let the bike be photographed with that cable hack job…

Under BB brakes = Hidden nipple tubular wheels, the devils doing. Neil Pryde does do beautiful carbon work though.
