This is our direct mount option for Prologo™ saddles equipped with accessory mount holes (see picture below). This mount base is attached to the OEM threaded inserts in the bottom of Prologo saddles equipped with this feature. It is designed to securely position a Bryton R300L radar, all Garmin Varia radars*, Magene L508 radar, Wahoo TRACKRradar, GoPro, Insta360, or similarly connected device for optimal visibility and operation.
Our standard kits are made from bio-plastic. Bio-plastic has very strong impact resistance, is comparable to injection molded plastics, and is environmentally friendly. The material is made from organic compounds instead of petroleum used in injection molded or other 3D printed plastics.

Saddle Compatibility
To check if your saddle has the required interface, look on the bottom of the saddle for two threaded holes as shown in the picture. If they are there, this direct mount will work with your saddle. If not, look at our universal saddle options instead.

This mount is intended for use with bicycles used on paved or relatively smooth unpaved surfaces. Our mounts can be used with electric bikes up to class 3. ASTM International standard F2043-13. |
BUP Shark Tooth Carbon Fiber (ST-CF)
What makes the Shark Tooth design different?
- ST Mounts use toothed connections to prevent slipping.
- Connections are very rugged and more than 3x thicker than GoPro type connections.
- Very easy to assemble using the provided thread locking screws.
- Eliminates the variations in GoPro like slot fitments for a more secure connection.
|---- Space ----|
- Our mounts move the device down and rearward to increase spacing.
- BUP mounts angles downward for more leg over clearance.
- Leaves plenty of room for most small or medium bags.
- Optional extensions can provide more space when needed.
Safety is not an afterthought
- Safety band prevents twist out release from impacts, aggressive riding, opportunistic theft, and accidents.
- Safety bands will not interfere with, or mute, radar range or operation.
- Elastic safety tethers are thin and exactly the same as the Garmin OEM computer tether.
- Heavy duty safety tethers are provided for heavier devices such as Garmin Varia RCT715.
Shark Tooth Grip
BUP designed the Shark tooth connector to eliminate device rotation. Standard action camera connectors (i.e., GoPro) typically suffer from unwanted rotation which requires overtightening the screw to overcome the rotation and that doesn't always work anyway.
ST-CF mounts use a thread locking screw that sandwiches the connector together. Easier to assemble and no way it will rotate. Just tighten normally and it is locked in place. Easy peasy.
Garmin
Compatibility
Besides being able to use all major brands of radars, our ST mount arms can be converted from one brand's radar to another. Switching between Garmin Varia and Magene require nothing more than unscrewing the insert rotating it 90 degrees. Conversion from Garmin or Magene to Bryton or Wahoo (or vice versa) is just as easy by swapping one insert for another.

Quality
Our mounts bases and arms are 3D printed with state-of the-art engineering grade materials using the latest manufacturing technologies. Small injection molded items, such as the quarter-turn inserts, are top-of-the-line and as good or better than the OEM part. We only use marine grade stainless steel hardware as well!
