Simplon is entering the fourth round with its long-running favorite, the Pavo. At first glance, the Simplon Pavo IV appears as the lightweight/aero hybrid it aims to be.
It presents itself in a completely tidy, dynamic look. No cable clutter in the front area, everything is internally routed through a special headset. The frame appears streamlined, unlike its more armored aero sibling model called Pride from the Austrian manufacturer by Lake Constance. It makes the hearts of weight weenies beat faster with a weight of only 800 g.
Finely built, with correspondingly light components and wheels, according to the manufacturer, a realistic minimum weight of 6.7 kg can be achieved with the Pavo IV.

The Vorarlbergers didn't go quite so wild with the test bike. The model equipped with Sram Force eTap, priced at around 8,000 euros, settled at 7.8 kg in size XS - this including a bottle holder.
XS? Yes indeed. As a test subject, Vanesa gets the beautiful opportunity to put the Pavo through its paces in a long-term review. Thus, numerous meters of altitude in the Bucklige Welt and elsewhere await the pair for a season.
To kick things off, here are all the facts about the bike and Vanesa's first impressions.

 The Pavo IV sets standards in the fusion of lightweight construction and aerodynamics – with a frame made in Europe.

Pavo IV Frame Technology

Lightweight construction and aerodynamics are often two opposing poles in bicycle frame building, whose optimal balance is difficult to achieve. Simplon's developers also had to face this challenge. The new frame design is based on complex flow simulations, in which every tube and every connection was optimized to achieve the best balance between low air resistance and minimal weight. To maximize stiffness, Simplon uses high-quality carbon fibers from the Japanese specialist Toray and relies on full-monocoque manufacturing in an autoclave at a manufacturer in Portugal. This is complemented by 3D-printed parts such as the front derailleur mount and stem spacers, which offer additional precision and lightness.

Autoclave Carbon Manufacturing vs. Hot Pressing Process

In contrast to the hot pressing process, which many renowned manufacturers in Taiwan and China rely on, autoclave carbon manufacturing offers even higher material quality and strength thanks to higher pressures, more uniform curing, and precise control over material properties. However, it is more expensive and time-consuming.

Here is the translation of the provided German text into English, keeping the formatting and line breaks as requested:```

Autoclave Manufacturing Hot Pressing Process
Quality Very high strength and stiffness, as air bubbles and irregularities are minimized. Good strength and stiffness, but possibly not as high as with autoclave manufacturing.
Precision Uniform curing and exact control over material properties. Can lead to less homogeneous products as control over the process is not as precise.
Cost/Benefit Expensive and time-consuming Cost-effective and faster

Similar to the hot pressing process, the carbon fiber layers are impregnated with resin and placed in a mold. After that, however, the entire mold is packed into a vacuum-sealed bag and placed under vacuum to remove air bubbles and distribute the resin evenly. Finally, the mold is moved into an autoclave (a type of pressure oven), where it is exposed to high temperatures (typically between 120-180°C) and high pressure (up to 10 bar). This cures the resin and bonds the fiber layers into a solid and homogeneous part, which, thanks to the higher manufacturing precision, requires little or no post-processing.

The result is impressive. Fully equipped, the Pavo IV is supposed to stop the scales at 6.7 kg. Vanesa's test bike settled at 7.8 kg with the Sram Force Etap AXS, aluminum wheels, and bottle holder.

Geometry

Even though the model name "Pavo" traditionally suggests something different, the fourth generation is a true all-rounder with a comfort-oriented racing bike geometry.
Thanks to the high head tube, the moderate steering angle, and the relatively long wheelbase, there is an upright, compact sitting position with stable handling. The short chainstays and the seat tube angle, steep at 75 degrees across all frame sizes, ensure high agility and the necessary pressure on the front wheel.

In Vanesa's review bike, the STR value of 1.42 indicates a relatively upright riding position, which should allow for good control and reduce the load on the back and neck. Generally, all values from 1.41 (XXS) to 1.53 (XL) show that the Pavo IV is more suited for long distances and cycling marathons than for aggressive racing situations.
With the general range of sizes, Simplon once again shows a heart for shorter people. Individuals under 1.60 m in height often struggle to find high-quality sports equipment. Vanesa, who is 158 cm tall, chose the XS (49 cm) size, and with a further available 46 cm frame, there is still plenty of room for smaller sizes.

Vanesa's First Impressions of the Pavo IV

Some further characteristics of the Pavo IV that stand out even before the first ride include the specially shaped seat post with a cutout for more flex and comfort, as well as the relatively comfortable frame geometry. Comfortable riding ultimately means fast and efficient riding. The frame leads with a steep seat tube angle of 75° and rather short chain stays, transferring the power from the pedal to the rear wheel and giving the handling a lot of agility.

The DT Swiss ER1600-30 Alu wheels contribute to comfortable riding behavior and make - despite their cost-effective entry price - an overall quality impression. Schwalbe's Pro-One in 28C further enhance the noble Pavo look with their Tan Walls. For those who find this wheelset not comfortable enough, tires up to 34 mm can be used.

Vanesa on the road

So I joyfully take the Pavo on its first review ride to Semmering and start right from kilometer 1 with an 8% incline, to get a first impression of the actual mountain suitability of this vehicle.
The altitude meters just tumble down. With the gearing of the Sram Force eTAP AXS Disc, I am well served: The combination of a 48/35 crankset at the front and a 12-speed cassette with 10-36 teeth provides me with enough gears for every situation and smooth gear changes without too large jumps. With the comparatively long crank arm of 172.5 mm, I manage well, and from a 10% gradient, I feel that the extra leverage brings me forward faster and more efficiently than with <170 mm. But I am also well-equipped for flat valley roads and descents, so that I never completely run out of gears even on speedy Semmering descents. The Pavo IV seems made for long days in the saddle.

In the coming weeks and months, I will continue to test the Simplon Pavo IV thoroughly to see if my initial positive impressions are confirmed and if the bike fulfills all its promises.
