Urban Stem Adapter
This mount was designed for bikes that already come fitted with an SP Connect stem interface. It lets you swap that existing SP Connect stem component for a Quad Lock interface, so you can use Quad Lock heads and accessories without needing to replace your whole stem or cockpit setup.
Please note:
- This product is not sold through our usual customer sales channels and is primarily supplied via retailers for specific bike setups.
- It provides a secure, low-profile replacement for compatible stems.
- Compatible with Quad Lock 360 heads and select stem designs (including JD and Satori).
If you're not sure whether your bike is compatible, please check with your bicycle manufacturer or contact our support team before installing.

What cycle applications are NOT suited?
This mount is not recommended for mountain biking or off-road use. It’s designed primarily for smoother urban and city environments, so it may not provide the level of stability required for rough terrain, jumps, or aggressive trail riding. For more demanding conditions, we recommend using a mount specifically built for high-impact and off-road applications like our other cycle mounts.
What cycle applications are suited?
This mount is ideal for everyday urban and city riding. It’s designed to handle regular commutes, casual weekend rides, and navigating through traffic with ease. Its slim profile and secure hold make it perfect for cyclists who want a low-profile, reliable phone mounting solution for paved roads and bike paths.
