Trek/Bontrager Garmin Quarter Turn Varia Mount
Stop fighting crooked and cumbersome radar mounts on your seatpost. This Garmin Varia mount is designed from the ground up for Trek/Bontrager saddles with the Blendr system, integrating directly into your saddle's rear mounting holes for a clean, purpose-built fit that stays put.
-
Bolt-in integration. Drops straight into the two rear Blendr holes — no clamps, no adapters, no wobble.
-
Built tough. ABS-GF (glass-fiber reinforced) construction handles the miles and the muck.
-
Featherlight. 23g all-in, including stainless steel mounting bolts.
-
Cleaner bike, cleaner mind. Keeps your seatpost uncluttered when the radar stays home.
-
Better line-of-sight. The elevated mount position means your Varia can actually see the road — not your wheel.
- Dropper-post friendly. Mounts to your saddle, not your post, so your radar moves with you and stays clear no matter where your dropper sits.
Compatibility: This mount fits Trek and Bontrager saddles with the Blendr system that have two rear mounting holes (see photos). It can be used with any Garmin Quarter Turn mount products.

Built by cyclists, for cyclists — designed and printed in-house with obsessive attention to fit and function. Like all 3D-printed parts, minor surface texture variation is part of the process. Not happy with yours? We've got you.
