Trek/Bontrager Varia Mount
Stop fighting crooked 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). Not sure if yours qualifies? Message us at support@backroadslab.com with your saddle model — we'll confirm before you buy.
Stainless steel mounting bolts included.
Garmin Varia radar and saddle not included.
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.
