KOM Cycling for Garmin Varia Mount Tail Light Models Including RTL515, RTL510, RVR315 Featuring an ATOP Dial for Security - Varia Seatpost and Under

The KOM Cycling for Garmin Varia Mount Tail Light is a convenient and secure option for attaching your Varia tail light to your bike. It is designed specifically for Varia models RTL515, RTL510, and RVR315, and features an ATOP dial for added security. However, there are some mixed responses from customers regarding its compatibility and stability on different seat posts. Some customers have reported that the mount works well on oval seat posts similar to Pinarello, as well as on thicker seat posts. However, others have expressed their concerns about the mount not fitting securely on round seat posts. They mentioned that even with tight cranking, the mount tends to move around and doesn't grip the seat post properly. Some customers have even found that the Garmin rubber-band mount is more stable and secure on round seat posts. On the positive side, customers have appreciated the low-profile design of the mount and its ease of installation. They also mentioned that it is quick and easy to move between bikes. Some customers have found the mount to be a better-looking and more secure alternative to the OEM mount. However, others have criticized the mount for not being as stable as expected, especially on round seat posts. One customer mentioned that KOM Cycling provides a new shim to fix the fit issue on D-shaped and round seat posts, which is sent free of charge. However, this shim is not included with the initial purchase and needs to be requested separately. Another customer suggested purchasing an additional accessory called Varia Mount Hexa-Grasp Shim for better stability on round seat posts, but noted that it comes at an additional cost and requires a separate shipment. In conclusion, the KOM Cycling for Garmin Varia Mount Tail Light is a convenient option for mounting your Varia tail light but may have compatibility and stability issues on certain seat posts. It is recommended for oval or thicker seat posts, but for those with round seat posts, alternative options or additional accessories may be necessary for a secure fit.
