A practical choice for riders, workshops and rental fleets that need a 90mm stem with a wide range of fit adjustment.
The PRO LT Adjustable Stem is a practical way to change your handlebar position without committing to a fixed-angle stem. With -30° to +40° of adjustment and clearly marked angles, you can raise or lower the bars to suit different riders, riding styles or bike setups.
Built from 3D-forged 6061 aluminium, the 90mm version keeps the specification straightforward while providing a durable alloy construction. The Headlock system secures the front clamp, while the removable four-bolt face plate makes handlebar installation easier and helps distribute clamping load evenly.
This stem is well suited to road, gravel and off-road bikes with a 31.8mm handlebar clamp and 1-1/8-inch fork steerer. It is particularly useful for test, rental or shared bikes, where quick fit adjustments make it easier to accommodate a range of riders.
