Garmin Arm Mk II Improvements
Broken quarter-turn inserts and disconnected Varia lights are a challenge for all Garmin Varia mounting options. These inserts are designed to be sacrificial, but can also weaken and break during normal use as well. At Bup Labs, we have grappled with this problem for years. Our mounts secure the Varia and prevent twist out, but they are still subjected to heavy loading depending on the bike and riding conditions. Bup's latest revolutionary design secures the Varia, prevents twist out, and removes the load from the insert. No other mount on the market does this.
The Problem With Garmin Varia Mounting
Upgrades and Support
THIS UPGRADE PROGRAM ENDED 2/1/2023
At Bup Labs, we are constantly evolving our designs to make cycling safer and provide the best mounting solutions. This wouldn't be possible without the invaluable feedback from our customers and testers who are cyclists of all levels.
If you already have a Mk I Garmin arm, it is designed to help mitigate the load on the insert and hold the Varia without issue. However, due to feedback from various users we identified that certain lots of specific quarter-turn inserts could possibly fail. We created a program to replace the affected inserts for free. There are two options for affected customers:
- Get a free replacement quarter-turn insert kit that replaces the problem insert
- Upgrade to the Mk II arm at a heavily discounted price.
For details see the KB-00008 - Free Garmin Insert Replacement article.
If your Mk I arm does not meet the criteria in KB-00008, there is no need to upgrade to the Mk II for fear of failure. We have thousands of units in the field that are working without issue. Only a narrow band of customers that are affected by the problem above should contact us for a replacement or upgrade.
