Best Overall: UPANBIKE threaded Steerer Tube extender

UPANBIKE threaded Steerer Tube extender
Buy on Amazon

The upanbike threaded steerer tube extender is long-lasting, rigid and fits well with your daily purpose like a dream. It's more of an adapter, or converter, than an extender. The purpose of this stem is to adapt the older headset and threaded bike steering tube to allow the use of the newer and larger mounting diameter stems. It allows installation of 1 1/8" stem. It's the diameter of the lower part of the stem that inserts into your steerer tube.

This part has no system to hold itself and raise your stem. It's tight to install but with grease it isn't impossible, it is much easier to remove than to install. The item is pretty light and very well made.

Why We Like This:
  • Finish is a bit soft and grainy
  • Great inexpensive way to update an older bike
  • Does a good job for conversion,very sturdy for going threadless
  • Simple inexpensive conversion from a gooseneck to a steering tube
