Garmin Varia mount for BTS system

You can still run your Varia off the seatpost. This is the tidier way to do it — bolted straight into the underside of the Aero BTS cup, centred on the bike, sitting further back than a seatpost mount puts it. Garmin quarter-turn interface — your Varia clicks straight in. No adapter stack, no rubber packers, no strap wrapped round the post Bolts directly to the Aero BTS cup — mounting bolts included, 20 g all in Sits at the rearmost point of the setup — nothing behind it, nothing overhanging it, clear rearward view for the radar and the light Fits the Aero BTS PRO and the standard Aero BTS — two versions, chosen by the date you ordered your system rather than by model
