The MITH Race RS puts RockShox coil suspension at the centre of UNNO's full-power enduro bike. A red ZEB Ultimate fork and matching Vivid Coil Ultimate shock sit against the forged-carbon finish, with 170mm of travel up front and 160mm at the rear. It's a build for riders who want to spend their climbing time earning another demanding descent.
The Avinox M2S drive unit supplies up to 130Nm in regular modes and 150Nm in Boost, with a maximum output of 1300W. An integrated 800Wh battery gives this long-travel platform a substantial energy reserve, while the top-tube touchscreen and wireless handlebar controller keep the system within easy reach. The supplied charger is the 168W, 4A unit.
A coil build with room to move
The Vivid Coil uses a custom UNNO tune and a spring rate matched to each frame size. A 63.5-degree head angle and mixed wheel sizes suit the bike's descending focus: a 29-inch front wheel for rolling through rough ground, with a 27.5-inch rear wheel that leaves more room to move over the back of the bike. Reach runs from 430mm in S1 to 490mm in S3, so the size choice is worth making carefully.
SRAM S1000 AXS T-Type shifting, Maven Base brakes and DT Swiss H1900 wheels make this a purposeful complete build. Schwalbe Magic Mary Gravity Pro tyres use Ultra Soft rubber at the front and Soft at the rear. The OneUp alloy bar and forged stem keep the cockpit straightforward, and cables enter the frame directly rather than passing through the headset - a useful detail when maintenance comes round.

A coil shock tuned for the MITH
The Vivid Coil Ultimate has a custom UNNO tune and a size-matched spring, giving the Race RS its own suspension character. Paired with the 170mm ZEB Ultimate, it makes this a compelling choice if your riding centres on rough, sustained descents.
Power for the climb back up
The Avinox M2S delivers up to 130Nm in regular modes and 150Nm in Boost, with an 800Wh battery integrated into the frame. The two-inch top-tube touchscreen and wireless controller put ride information and assistance controls close at hand, ready for the next lap.
Descending room, deliberate sizing
A 29-inch front wheel, 27.5-inch rear wheel and 63.5-degree head angle give the MITH its descending focus. The smaller rear wheel leaves space to move on steep ground, while three frame sizes offer 430, 460 and 490mm reach. Choose by fit and handling preference, with the geometry table as your guide.
A complete build for demanding trails
SRAM S1000 AXS T-Type provides wireless shifting across a 10-52t cassette. Maven Base brakes use 200mm HS2 rotors, and DT Swiss H1900 wheels carry 2.5-inch Magic Mary Gravity Pro tyres. The Ultra Soft front compound prioritises grip, with Soft rubber at the rear.
