This kit requires a compatible BUP mount base.
The BUP RTL510-515 SL mount arm positions the radar horizontally for clearance below the mount point. There is no issue using the RTL510 or RTL515 Varia in this manner (Specialized bike racks with integrated Garmin radars do this). This add-on kit is ideal for bike racks that have reduced clearance over the rear tire or saddle setups with large saddle bags.
This add-on mount arm kit uses the standard quarter-turn connector used by all models of Varia radars except the RCT715 (See Garmin RCT715 kit). This kit includes everything needed to attach your RTL510 or RTL515 to our supported mount bases and includes a safety tether.

Features of the Garmin Varia RTL510/515 SL arm kit
 |
Our quarter-turn inserts are the same as the Garmin OEM quarter-turn inserts. These inserts are thicker and harder to flex but unfortunately much more expensive to manufacture. That is why virtually all 3rd party computer and Varia mounts on the market use inexpensive inserts with two holes for flat head screws. They are thinner and more prone to failure. |
|---|
| The 515 SL mount arm has integrated hooks to hold a strong rubber retention ring that prevents accidental release. The integrated tether hook attaches the entire arm to the bike to help mitigate loss in the event of a crash. |  |
|---|
 |
Because the Varia is mounted sideways, the center of gravity is well balanced and much less likely to pivot under loading. The horizontal layout allows the arm to be attached to bike racks even when the accessory mount is tucked under the rack. |

All BUP mounts are manufactured and hand assembled in the USA

What are these products made out of?
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.
Where are your products made?
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).
Do you ship to my country?
We currently ship within the U.S., most U.S. territories, and Canada. Please see the international shipping page for more details.
