The favorite Bike of fast Ladies.

When trail riding, comfort is a necessity.  And the Mira offers plenty of it - from the compact, light aluminium frame with reduced standover height and the finely tuned air suspension fork to the Shimano SLX/Deore 3x10 speed drivetrain and reliable disc brakes. Wheel size (27.5 or 29) is matched to frame size.

  • Lightweight lady hardtail w/ size specific wheel sizes (27.5"/29")
  • Solid Shimano SLX/Deore 3x10-speed drivetrain
  • Responsive RockShox air/oil suspension fork w/ tapered steerer
  • Reliable, precise Shimano disc brakes
  • Lowered top tube for optimized standover height

Technology

Hydroforming

Using water or oil pressure aluminium tubes are transformed from their original round shape into their ideal shape determined by STEVENS engineers to perfectly withstand any load without any weight penalty. This means better steering precision on the trail and higher longevity.

Tapered Steerer / Tapered Headtube

Fork shaft (or steerer tube) and head tube are tapered, meaning their diameter increases from top to bottom resulting in a conical shape. The diameter needs to be bigger at the bottom since this is where higher stress is applied - especially when the bike has a higher total weight due to luggage or an e-drive and battery. Also tapered steerers feature a smoother force transfer (like forces caused by hard braking) to the downtube than forks with a continuous 1 1/8" diameter.

Triple Butted, Double Butted

Meaning a frame tube has three or two different wall thicknesses along its length. Triple butted (TB) is the usual technology with STEVENS high-quality frames.
Tubes with different wall thicknesses are optimally adjusted to certain ways of manufacturing or to withstand specific loads. Where the highest loads occur or where tubes are welded, walls are the thickest. Butted tubes allow frame weight to be lower by several hundred grams.
