This 2nd Generation Bup mount for Topeak Beamrack MTX bike racks will attach a Garmin Varia in place of the OEM reflector. It is designed to match the style of the Beamrack and not interfere with the quick release functionality of the rack.  The mount will securely position a Garmin Varia for optimal visibility and operation free and clear of the items on the bike rack.

INTENDED USE

Usage rating 

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.


2nd Generation Improvements

We switched from the previous quarter-turn insert to the thicker and more durable standard Garmin quarter-turn insert. This insert is stronger and able to absorb greater loads and is directly compatible with the OEM version. Gen 3 vs Gen 2 positioning
Nyloc screws and locknuts Like our standard Garmin Varia mount arms, we added a tab at the bottom to help mitigate the torsional loads on the quarter-turn insert. This makes the mount even more reliable than the previous generation.
This mount will accomodate all Garmin Varia models except the radar/camera Varia RCT 715. Garmin arm CG changes

BUP Shark Tooth (ST)

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 mount positioning creates more leg over clearance for easier mounts and dismounts.
  • Leaves more than enough room for most small/medium and even some large bags.
  • Optional extensions can provide even 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.
  • New elastic safety tethers are thin and exactly the same as the Garmin OEM computer tether.
  • Heavy duty safety tethers are provided with kits for heavier devices such as a GoPro or Garmin Varia RCT715.

Shark Tooth Grip

One huge benefit of the new Shark tooth design is preventing device rotation. Standard action camera connectors typically suffer from rotation under loading which requires overtightening the screw to overcome the rotation. Overtightening can eventually lead to damage or failure.

ST mounts use just one thread locking screw for easy assembly. Just tighten normally and it is locked in place. Easy peasy.

Have Your Cake And Eat It Too

Radar and a GOOD camera? Yes please! Extra room for big saddle bags? Yes please! Pick one or the other? Nope! Bup horizontal mount arms provide a huge amount of space below the saddle AND the option to run two devices at once!

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 and moving a few plugs. Conversion from Garmin or Magene to Bryton (or vice versa) is almost as easy with an extra insert (sold separately).

Magene

Quality

Our mounts bases and arms are 3D printed with state-of the-art bioplastic materials using the most technologically advanced machines in the world. Even small injection molded items, such as the quarter-turn inserts, are top-of-the-line and as good or better than the OEM part.

Frequently Asked Questions

Our mounts are made from a new state-of-the-art material called bio-plastic that is derived from plants instead of petroleum. It is stronger than traditional plastic and able to withstand repeated impacts better. Some components are made from injection molded plastic or steel.

We source all raw materials, manufacture the primary components, assemble, and package the products in the United States. Some accessory items or minor components are imported (noted in the product details).

We currently ship within the U.S., most U.S. territories, Canada, United Kingdom, and Australia. Please see the international shipping page for up-to-date shipping locations and more details.
