Classified Powershift Boost Hub System: The Game-Changing Two-Speed Gear System for Mountain Bikes

The mountain bike industry has been dominated by SRAM and Shimano for decades, with both companies producing high-quality components favored by professional riders and casual cyclists alike. However, a new contender has entered the market with a potentially game-changing innovation. Classified, a Belgian cycling start-up, has unveiled a revolutionary new drivetrain system that offers a significantly wider gear range than even SRAM’s top-of-the-line Eagle system. This development is poised to shake up the mountain bike industry and has many enthusiasts excited about the possibilities it presents.


Classified has recently released their Powershift Boost hub system designed for mountain bikes. The system features a two-speed gear system located in the rear hub, allowing for the range and gearing of a 2x setup without the need for a front derailleur. The system is compatible with 11- and 12-speed mountain bike groupsets and comes paired with an 11-40t 12-speed cassette and a bar-mounted remote named the Ringshifter. Classified claims that the system can be shifted under loads of up to 1,000 watts, and shift speed is 150 milliseconds in either direction. The hub is available in three options: a hub set with a hub shell for €1,549, without a hub shell for €1,449, or as part of a Classified wheelset for €2,699. The new M25/30 hookless carbon wheelset has a 30mm internal rim width and 25mm depth. Classified claims that the Powershift Boost hub is paired with the largest gear range of any drivetrain on the market to date. The one-piece steel cassette has a gear range of 530 per cent, designed to avoid cross-chaining with a sprocket jumps cassette of 11, 12, 13, 14, 15, 17, 19, 22, 25, 29, 34, 40. Classified has also debuted the Ringshifter, which is a wireless shifter mounted to the handlebar that controls the two-speed hub. It weighs 24g and can perform 10,000 shifts before needing to be recharged with a USB cable.


In conclusion, Classified’s entrance into the mountain bike market is a game-changer for cycling enthusiasts. With a wider gear range than SRAM, riders can tackle steep inclines and intense terrain with ease. Not only does Classified offer performance-enhancing components, but the brand also boasts a sleek and minimalist design. It’s clear that the future of mountain biking is evolving, and Classified is leading the charge. Stay tuned for more innovations from this dynamic brand. Happy trails!
