  • ★ Please confirm your bike handlebar diameter is 31.8mm (1-1/4″) before order!!! Otherwise, the item is not suitable for your bike.
  • ★ The bike stem is sturdy, well designed and easily adjusted, which is preferable to removing the handlebar stem and exchanging it for one with a different angle.
  • ★ The installation is easy because the specs were accurately represented. There is a “degree of angle” indicator on the adjacent parts to allow you to set your angel correctly. The stem has a opening that allows you to see where the handle bar is positioned.
  • ★ This is a pretty nice riser, good adjust-ability. Depending on the thickness of your handlebar, you may need to install a shim. Be sure to use glue on threads if any loosen up.
  • ★ Use the adjustable stem to achieve a more comfortable riding position, the pain caused by the original setup in shoulders/arms/back had to be corrected. This stem and a riser handlebar did the trick, allow you to sit more upright on bike which is better for your back.
