Bublab varia mount for Specialized SWAT seat. They support other saddle brands also.
Installed, very easy.
I purchased the Garmin Varia RTL515 with intentions of hanging it some how off my saddle bag. The old bag in the pic wasn't the one I was thinking of. This will eventually go on is on a road bike. But, since I really have enjoyed the Specialized expert power when the new bike shows up in December I'll be ready.
First, Buplab did an excellent job shipping it out, and communication is very cordial and professional. The kit is super well done, includes everything needed to support multiple saddle bag configurations. My particular setup didn't need the 2 extra extensions but I have the if needed. Came with locktite, tether, and Allen key and plenty of instructions. My particular purchase is for the SWAT sys they support other saddle brands also. Now, The Varia light/radar is really very cool love the integration with my Edge 830. Hope it lasts. Buplabs.com
