Description:Eliminating damage and providing additional support to the fragile top of the bike fork

Can firmly connect the bike front fork and stem

Wide Usage: Tools to help you replace your old broken bicycle, useful accessories for MTB, mountain bike, road bike, folding bike, etc

With a total length of 45mm, our expander plug should cover most stem’s stack height

The bolts of the stems are evenly tightened with our expander plug inside

If using a smaller so-called extra lightweight expander plug, the bolts of the stem may cause stress and crack the bike fork’s steerer tube

A damaged fork may break if continued to be used, posing fall or injury hazards
