Configurator · Step 1Configurator · Step 1
How it works

Three steps. No tools.

MONO sits on your seatpost with a form fit. Open, wrap, click in. No screws, no Allen key.

01

Open.

Reach into the recess and pull the ring forward off the adapter. The mount opens wide enough to fit around the seatpost.

02

Wrap.

Wrap MONO around the seatpost and press lightly until it sits flush all round. The form fit grips the geometry of your aero or round seatpost right away. No rubber shims, no slack.

03

Click in.

Press the ring over the adapter until you feel it click into place. MONO now sits tight and vibration-proof on the seatpost. Then insert the Garmin Varia and turn it a quarter turn.

Mounted in secondsThree moves and the mount sits on the seatpost. Nothing to adjust afterwards.

OpenReach into the recess to release the ring, and the mount opens.

FitThe mount is designed for the shape of your seatpost and printed in Nylon PA12 CF, around 15 grams. It sits flush against the post.

Tool-freeThe ring holds the mount closed by form fit, no tools needed.

MONO was on in no time without any tools and hasn't moved since. You barely notice it on the bike. That's exactly how a part should be, I think.

Second order – as you’d expect, everything went really smoothly this time too. The communication with the company is excellent, by the way. They reply straight away to any queries you might have if you’re not sure which mount is the right one. It also looks absolutely brilliant on my dream bike 🤗

I’ve just picked up my mount from the post office and I have to say: I’m absolutely thrilled! I’d already reckoned it would look good, but I really didn’t expect it to look THIS good. It looks so neat and clean on the bike – simply lovely. 😮‍💨 I think I’ll order another one straight away next month for my Canyon Grail. I can’t just leave it like this. Once you realise how good it can look, you simply don’t want any more ‘rubber bands’ on your bike! I absolutely recommend it!

Wenn man spürt, dass jemand sich richtig viel Arbeit gemacht hat, um ein vollkommen einfaches Produkt zu schaffen. Bombenfest, sicher, leicht- ohne Gefummel. Ein grosser Wurf!

The best mount for the Varia! It fits snugly against the seatpost, so it’s barely noticeable and doesn’t detract from the bike’s overall aero and race look. The mount is superb quality and can be fitted without screws (simply clip it on and off you go), meaning the position can still be adjusted at any time if needed. Straightforward payment and delivery – what more could you want :)

A brilliantly designed Garmin Varia mount. Sturdy, lightweight, durable, with a cool, aerodynamic design. A truly brilliant product from a thoroughly reliable company. I can highly recommend it.
