The ability to have smaller jumps between cogs could prove an advantage in [cross-country racing](https://www.bikeradar.com/advice/fitness-and-training/cross-country-racing-guide/) too. Will Classified be able to change MTB gearing once again? The brand claims it uses a ‘unique magnetic spring back mechanism’ to improve feedback through the shifter. Only time will tell. The Powershift Boost hub is paired with a new Classified 11-40t 12-speed cassette. [gravel bikes](https://www.bikeradar.com/advice/buyers-guides/best-gravel-bikes/).

SRAM voltage envelope below 0.5-V for the first time (eeNews Europe)

PowerMiser Plus SRAM is ideal for power critical Edge-AI applications that must provide significant inferencing power with acceptable battery life.

Whilst a bespoke optimisation offers the opportunity to engineer the optimal fit for the target application, sureCore has a range of power-optimised, standard products that deliver market-leading power profiles so urgently needed by these applications. This successfully delivered the low voltage solutions needed by our customers enabling them to hit their challenging power targets.” For one customer, sureCore ported the PowerMiser Plus architecture to a leading 12nm process interfacing to logic operating at 0.45 V whilst delivering 400 MHz performance at the worst-case corner. SureCore has exploited its low power design capability to create a new range of ultra-low voltage SRAM products, called PowerMiser™ Plus, that can operate down to 0.45-V. Key to delivering the power savings demanded is the wholesale shift of the application to a lower operating voltage which is fine for the logic, of course, which can still deliver relatively high performance. Whilst operating at 0.6 V nominal and delivering 400 MHz worst case, the memory was also characterised to operate at 0.5 V providing dramatically extended battery life.

Classified 2x Goes Off-Road in Single 12sp Shimano/SRAM ... (Bikerumor)

Classified 2-speed internal Powershift MTB hub brings 2x drivetrains back to mountain bikes with one new 12-speed cassette for both Shimano & SRAM ...

The Shimano AND SRAM compatible cassette includes the following gear steps: 11-12-13-14-15-17-19-22-25-29-34-40. Also new but pretty obvious, the new MTB system is Boost spaced, which means it isn’t a direct swap with other Powershift internals. Classified says Powershift MTB 12sp delivers 16 unique gears (after factoring out duplicate ratios) with a bit of a combination of derailleur & hub shifting. But the Classified Ringshifter remote is completely self-contained and wireless – and rechargeable with a proprietary USB dongle after 10k shifts – making it incredibly quick to install in between your grip and brakes. That’s right, with wireless electronic shifting and just one 11-40T Classified cassette, Powershift will bump up your MTB gearing range to 530% whether you are riding a Shimano 12sp or SRAM Eagle 1x drivetrain… Pairing the 11-40T cassette with the internal reduction gear allows mountain bikers to size up their chainring by about 10-15% while getting both easier AND harder gears thanks to the system’s broad 530% gearing range.

sureCore reduces SRAM voltage to 0.45V (Electronics Weekly)

sureCore, the Sheffield low power SRAM IP specialist, has created a new range of ultra-low voltage SRAM solutions, called PowerMiser Plus, that can.

This successfully delivered the low voltage solutions needed by our customers enabling them to hit their challenging power targets.” This meant that the use of power-hungry level shifters within the SRAM were avoided, thereby further optimising power consumption. For one customer, sureCore ported the PowerMiser Plus architecture to a leading 12nm process interfacing to logic operating at 0.45V whilst delivering 400MHz performance at the worst-case corner.

24-speed Classified MTB Drivetrain is Wireless and Technically 1X (Singletracks.com)

The Classified Powershift drivetrain pairs a 12-speed cassette with an internally geared, wireless, 2-speed hub that effectively serves the same purpose as ...

This allows Classified to save significant weight on the 248g cassette, bringing the total system weight with the hub to within about 170g of a Shimano XTR or SRAM XX1 cassette plus hub combo. Pricing for a Classified wheelset with a Powershift system is set at €2,699; a Powershift set by itself costs €1,549. The Classified Powershift hub weighs 485g which is significantly heavier than a traditional mountain bike hub like the Industry 9 Hydra that weighs about 300g. The electronic hub is powered by a battery that’s located inside a special thru axle. The Classified Powerhub is internally geared with two gears. Classified has a unique drivetrain system that’s been getting a lot of press in the road and gravel bike worlds, and today the brand is taking the wraps off their MTB group.
