The Pro Stem LT OS in 90mm black is adjustable from 30 to 40 degrees, offering high - performance for your cycling needs.

Using this stem is easy. First, make sure your bike's handlebar has a 31.8mm diameter that fits the clamp. Loosen the clamp bolts, adjust the stem to your desired angle between 30 and 40 degrees, then tighten the bolts firmly. When riding, check occasionally that the stem is secure. For maintenance, keep it clean by wiping it with a dry cloth regularly. Avoid using harsh chemicals as they may damage the finish. If you notice any signs of wear or looseness, have it checked by a professional.
