50/50 Prime Jon Fromm - White/Gold

  • Hedon Apparel Sweaters

50/50 Prime are frames for aggressive skating, based on revolutionary Core System 2 concept, which means a mix of an sturdy, aluminium core and replaceable, plastic side walls. Getting back to market from little hiatus, 50/50 offers a solution that perfectly matches the current equipment trends. With aluminium frames getting more and more popular among aggressive skaters, the need of proper energy transfer is the key feature looked for. Yet, the most of the available aluminium frames are designed for skatepark use due to lack of good grinding properties while street skating. In response to this problem, 50/50 introduces the fix in the form of Prime frames.

Mounted with only two, outer wheel axels, the plastic side walls will assure smooth grinds on every kind of obstacle. Easy yet smart way, giving us a universal frame, which we can count on in all conditions.

Commonly used as anti-rocker frame, can be a great alternative to skating with eight wheels down thanks to large 120 mm split between middle wheels (flat setup is possible with maximum wheel size of 60 mm). The groove is wide and quite deep — it facilitates the correct lock with any of royale based tricks. Single tool 8 mm axles for easy wheel replacement.

Thanks to its unique aspects, the 50/50 Prime frame gives the user unmatched durability. Rigid. Aluminium core is covered with lifetime warranty while the plastic sidewall can be changed anytime. Also, with the wide access to 3d printing technology, nothing stands in the way in making the sidewall by yourself. The internet is full of free and ready-to-print projects, which additionally can be modded for any custom needs. We can easily transform the 50/50 Core into a freestyle or even hi-lo frame. The possibilities are only limited by our imagination (and of course our designing skills).

The premiere version of 50/50 Prime is the pro model of a technical blader from California — Jon From. Jon was actively participating in the development process, by testing all the prototypes. His signature frame comes with bright white side walls with a printed logo in metallic gold, matching golden axels and anodized core.

Founded back in 1994 in California, Fifty/50 brand was established by Jess Dyrenforth and Ted Simpson. One of the oldest rollerblading company on the market, it broke the trends by making the products aimed exclusively to aggressive oriented customers. Fifty/50 was created to fulfil the growing needs of freshly emerged sport and quickly became manufacturer of specialized parts for inline skates.

The company started it all with the production of first after market grindplates. Made of characteristic mix of aluminium and plastic (hence the name Fifty/50), the grindpplates noticeably facilitated any grinding experience. It was the first, big success of the brand, followed by wide offer of signature products of well known skaters at that time. Next, the company came up with the idea of designing the after market frames to catch up with constantly growing demand.

Premiere, one piece Fifty/50 frames were made with CNC method and were quickly adopted by aggressive skating community. As the UFS had been not invented yet, the different mounting standards were quite problematic. Fifty/50 products came included with dedicated adapters for every type of skate boot. Yet, the cost of the machined frames was too high, and the materials weren't ideal, so Fifty/50 decided to switch to moulded frames. To make assembling a bit easier the idea of adapters was still here, but this time they were made of UHMW. The whole part was called 'Juice System' and it was another milestone in the company's history. This great solution became very popular among most of the professionals. The brand had earned the respect and trust of the customers and boldly entered the upcoming new decade of 2000.

Once the UFS mounting system became a standard, more and more frame manufacturers started to appear on the market. The brand tried to stay afloat for some time, yet growing competition unfortunately pushed it back. Occasionally, we could find small drops of products here and there, yet the brand almost disappeared for next few years. Around 2017 though, one of the original member of Fifty/50 crew Lawrence Ingraham decided to bring the idea back. Luckily the comeback was warmly accepted by the community and since then the company has been a solid provider of after market inline skating goods.

Nowadays Fifty/50 focuses mainly on frame production but also offers wide selection of inline skating wheels, backpacks and useful accessories. Professional skaters such as Stefan Brandow, Chris Farmer, Jon Fromm and Sacha Lopez have been constantly striving for the company's good image.

Fifty/50 offer includes products like classic and proven Balance frames, as well as modern solutions like Prime frames. A unique idea of a flat frame with aluminium core and replaceable plastic sidewall is getting more and more attention nowadays, making Fifty/50 a respected part of our industry.
