Spusu Road Bike Ultegra Di2 2026

Spusu is an Austrian mobile network provider and has been a fixed part of the domestic market since 2015. The name stands for "speak and surf" - short, memorable, and entirely in line with the company's philosophy: communication should be simple, honest, and transparent. Calls and internet usage are made via the Drei network. Spusu was founded by Dipl.-Ing. Franz Pichler, who continues to lead the company as owner and managing director.

With the motto "Mobile service without hidden costs", spusu has made a name for itself. And not just with attractive tariffs, but also with customer service that is genuinely accessible. Most inquiries are resolved within a few minutes. It’s no surprise then that the company has been repeatedly awarded as a test winner. Today, spusu counts around 700,000 customers in Austria, Italy, the United Kingdom, and Switzerland, employs over 300 staff, and generated a revenue of 81 million euros in 2024. 

In the meantime, spusu has expanded far beyond mobile services: in addition to the development of regional fiber-optic infrastructure and its own wine division, the company has also been dedicated to bicycle manufacturing since 2022. In its in-house workshop in Wolkersdorf, Lower Austria, high-quality bikes are developed, built, sold, and serviced.

The bikes are available in stores in Vienna, Baden, Vöcklabruck, and Wolkersdorf or online.

Across all frame sizes, the geometry clearly exhibits a sporty character. Relatively short chainstays and compact wheelbases ensure agility, while the combination of steep seat angles and reasonable head tube lengths creates a balanced blend of efficiency and comfort, depending on the size. This is designed to provide an appropriate riding position for both smaller riders with compact proportions and taller riders with more stack.

Our test bike in size 54 sits in the middle of the range. With a stack of 557 mm and a reach of 381 mm, it offers a sporty-neutral fit that allows for a slightly stretched but not extreme riding position. The seat angle of 74° positions the rider efficiently over the bottom bracket, which is beneficial for climbing sections. The head angle of 73° combined with the 45 mm fork offset delivers direct and precise steering.

The geometry of the size 54 is primarily aimed at sporty riders with a height of approximately 170 to 180 cm, who are looking for a classic road bike geometry for training, ambitious tours, and races while valuing a direct and very agile riding experience.

Particularly striking is the enormous stiffness of the frame and fork, which ensures exceptional sprint strength and high steering precision. Together with the crisp geometry, the bike delivers very agile handling, supporting quick directional changes and sprint-ready acceleration. A small note: Due to the relatively steep head angle in combination with the mounted wide tires, there can be toe overlap during tight steering maneuvers – when the front wheel is turned sharply, the shoe can quickly come into contact with the tire.

With the third generation of the ARC 1100 DICUT DB , DT Swiss brings its most versatile aero setup to the road yet. The wheels are offered in 55, 65, and 85 millimeter rim heights. All models share the 180 DICUT hub with Ratchet EXP system, SINC ceramic bearings, and the new DT aerolite II spokes. The entire setup was developed with a clear goal: greater aerodynamic efficiency, improved ride stability, and a balanced combination of weight and stiffness, tailored to various use cases.

For our review, we had a wheelset with a 55-millimeter rim height at our disposal, equipped with a Continental AERO 111 in 29C at the front and a Continental GP 5000 S TR in 30C at the rear. The setup was complemented by matching TPU tubes from Continental.

That wider tires are increasingly being used in professional cycling is no longer a secret. However, for them to reach their full potential, an appropriate internal rim width is required. The new ARC models feature an internal width of 22 millimeters. Technically, an even wider design would have been possible, but the focus was on achieving perfect compatibility with the 29-millimeter-wide AERO 111 tire, which has now established itself as the new aero standard.

A larger internal width directly affects the frontal area of the wheel. To compensate for the associated aerodynamic disadvantages, DT Swiss relies on a V-shaped rim profile. According to wind tunnel tests, this design not only delivers the lowest measured base drag but also reduces steering torque. The result is stable and controlled handling that impresses even in crosswinds.

The details were not skimped on either. Thanks to the in-house modular system and the pooled expertise, all components were precisely matched to each other. The goal was a wheelset that not only impresses aerodynamically but also offers first-class ride performance. The specially aero-optimized spokes make an important contribution to this. Their number has been reduced to 20 on the front wheel, which slightly lowers air resistance while also saving weight.

In the coming weeks, we will ride the wheels as often as possible under a variety of conditions. Our focus is on everyday usability and durability. When it comes to aerodynamics, however, we have no choice but to rely on the data provided by DT Swiss. Thanks to the detailed analyses, it should still be easy for aero enthusiasts to assess the performance according to their own requirements.

For us personally, aside from aerodynamics, two points are particularly important: high stiffness and minimal susceptibility to crosswinds.
