What Our Gearhead(R) Experts Are Saying:"I switched to the Saddle Rail Mount for Rear Radars because I wanted my Garmin Varia in a cleaner position than the seat post allowed on my road bike. The 25mm pivoting arm let me dial the angle in precisely, and the rubber shims gave me confidence that my carbon rails were not taking any risk from the clamp. The radar sits tucked neatly under the saddle, and the position is ideal for both vehicle detection and visibility from behind."Seat post mounting works until it does not. A dropper post, a seat bag, an aero post with no clamp point, or simply a preference for a cleaner setup can all put your radar in a compromised position or out of commission entirely. The KOM Cycling Saddle Rail Mount for Rear Radars moves the attachment point to the saddle rails themselves, positioning your Garmin Varia or Wahoo Trackr directly under the saddle where it has a clear and unobstructed view of approaching traffic. The 69mm rail clamp and 25mm pivoting extender arm give you the adjustability to get the radar angle exactly right, regardless of your saddle geometry, and the mount installs on either the vertical or horizontal sections of the rails to work with your specific setup. Integrated rubber safety shims protect alloy and carbon rails alike, and an included oversized spacer extends compatibility to 9mm and 10mm rails. The polycarbonate construction keeps the whole assembly light without sacrificing the rigidity needed to hold a radar unit securely through real riding conditions.
