In this article I will share my thoughts on the BeSmartBike Holder for Garmin Varia RTL515 on Canyon SP0094 Seat Post of Canyon Ultimate CF SLX 8 Di2. It is a bolt-holder for the Garmin Varia Radar / rear light. The standard Garmin Varia RTL515 holder works with rubber bands that wrap around the seatpost, just like the Sigma Nugget II Flash Rear Light.
