I have a classic SPC Universal Bike Mount with straight rails. How can I upgrade to the new system with half-circular rails?Updated a month ago

You can easily upgrade your existing SPC Universal Bike Mount to the current system with half-circular rails – without having to purchase a completely new mount. Simply replace the existing SPC mounting head (with straight rails) with the appropriate upgrade head:

•   Head SPC+ Brake, Micro Bike, Uni Bike, Mirror  

How the upgrade works:

1. Remove the existing SPC head (straight rails) from your mount.
2. Install the Head SPC+ Brake, Micro Bike, Uni Bike, Mirror instead.
3. After that, you can enjoy the many benefits of the current system.

In short: Only the head is replaced – the rest of the mount remains the same.
