Very low mounting with headset cap Lightweight aluminum Only compatible with M6 threads. For mounting the mobile phone, an additional SP Connect Phone case required Note The Micro Stem Mount Alu is particularly useful when used with road bikes. Since our product is mounted directly on the frame of the road bike, you should also make sure that the bicycle stem is flat enough beforehand. The Micro Stem Mount serves as a flat mount option, but if the bike stem is steep or uncomfortable, we recommend the universal or handlebar mount.
