Product details
Seba UFS Street are definitely one of the most interesting and at the same time underappreciated aggressive inline frames on the market right now. They were designed in a very smart way: their walls are not flat, but are cut-out to leave only outline of the frame to have contact with grinded surface. The less contact area means less friction, which means that they slide better on soul and more importantly, topside tricks.
Another thing worth praise is their rockering system. You can adjust axles position by 2 mm, which allows you to make your setup more agile or experiment with different wheel sizes. The frame will fit 4 x 60 mm flat setup, with all axles positioned down.
It is also possible to use a lower height, mixed wheel size flat setup. Just use 60 mm wheels in outer positions, rocker them up and place 56 mm ones in the middle and rocker them down. In addition to lower height this will help to reduce wheelbite. Rockering opens up a lot of possibilities when it comes to wheel setups and makes Seba UFS Street a very sensible choice for riding flat. Of course, nothing stands in the way of using these frames with antirocker setup.
It is worth to point out that if you have experience with earlier versions of the frame, which came stock on a couple of first generation Seba CJ skates, these underwent some changes in comparison. Their groove is wider and you can use bigger wheel sizes with them. They come in several different colours, too. They match Seba CJ and SX custom kits but furthermore, also those released for FR Skates FR line, which in turna are compatible with new UFR street skates from the brand. Thus, there’s a possibility to achieve some rad colour schemes in two different boot types.
A huge advantage of these frames is included hardware. Axles and spacers are of great quality – you do not have to worry about damaged allen key slots or screw threads.
There are three frame sizes available:
- S: 250 mm long, recommended for boot sizes EU36-EU40
- M: 260 mm long, recommended for boot sizes EU41-EU43
- L: 270 mm long, recommended for boot sizes EU44 and bigger.
Of course, all length variants are UFS compatible, so if you, for example, want to experiment with a long frame with rockered setup, mounted on a smaller boot size, the option is there.

About manufacturer

Seba Skates is a highly recognized brand in the inline skating community, particularly known for its freestyle slalom skates. Its story dates back to 2005, when French freestyle champion Sébastien Laffargue decided to create skates specifically tailored to the demands of this dynamic discipline. At the time, the market was dominated by all-purpose models that did not meet slalom’s specialized needs, so Laffargue developed a line of skates designed to fill this gap.
From its inception, Seba has prioritized high-quality construction and top-notch performance, focusing on control and efficiency. These skates quickly gained a following among freestyle slalom and urban skating enthusiasts, especially thanks to ongoing innovations such as customizable components (adjustable cuffs, diverse frames, and liners). Around 2019, a new brand — FR Skates was introduced, and part of Seba’s existing lineup was split between the two companies. From then on, each brand has evolved independently, although they continue to share certain technological solutions.
Today, Seba Skates offers a wide range of models: from basic urban skates (Seba E3) to those designed for aggressive and wizard skating (Seba CJ), as well as integrated boot options (Seba GT, High Light). In the freestyle slalom category, standouts include the Seba Trix and High Light Carbon, while long-distance enthusiasts can opt for the Seba Marathon. The brand also caters to young skaters with children’s models like the Seba J and ST MX. Thanks to this diverse portfolio, everyone—from beginners to experts—can find a suitable pair of Seba skates.
