Review: Best mount alternative for non-standard seat posts - I haven’t ridden with this mount as of this writing but it sure looks sturdy. Although there is a little sway side to side, it won’t get dislodge during the ride. Definitely secure vertically. I actually bounced the rear wheel quite hard and it didn’t move a mm up or down or sideways. I used the optional wedge which worked well with my Madone Gen 8 Seatpost. See pics. I only hope that the non abrasive cable would last a long time and won’t get cut. It is actually a good material choice since it will not damage carbon. I will still put a plastic film similar to ride wrap just to make sure paint won’t be damage during normal use.
Review: Easy to install & works for many bikes - It is great to know that this garmin varia mount was built for ease of use. With different size seatposts and mounting areas on different bikes, I am able to move this mount between my bikes within a minute or two. The tightening mechanism is strong and overall, after using it for a while, I am confident that it will last for a long time. Great product overall!

## Questions & Answers

**Q: Does this fit Pinarello seat posts securely?**
A: I have a 2021DeRosa SK that have an oval seat post which is similar to the Pinarello. Therefore it should. Just look at the DeRosa SK 2019 to present and compare seat post. Hope this help. Great product I love it.

**Q: Will this mount on the seat stay?**
A: I don’t think so.  Yes, it would fit around the stay but I don’t think it will tighten to such small size.  It’s intended for thicker seat post.  Again just my opinion.

**Q: Can a Garmin Edge 520 stay in this mount? Or is the Varia and Edge computer mount different size?**
A: This item is designed for the Varia on the seatpost.  It may work on the handlebars but have not attempted.  I have a Garmin 1030 which will fit on the mount

**Q: Will Varia RTL500 RTL501 fit?**
A: Yes..I use my Varia using it.. Tightens pretty well...

### ⭐⭐⭐ KOM, test your stuff and react accordingly!
*by P***F on August 1, 2024*

UPDATE: As I said I would, I wrapped a piece of 3M Protective Tape around the section of seat post and the mount seemed to grip A LOT better -- almost no slipping down and harder to rotate the Varia. I took it on a 64-mile ride that included some very bumpy asphalt and the unit barely moved, but certainly never loosened or slipped down and failed as it had during an 18-mile ride on smooth roads. One thing I plan to redo, is wrap a longer section of the seat post, to give the mount a chance to settle into a spot that's still wrapped with the tape, because the wires held their position but the rubber grip did tend to want a lower spot than the wires (as you can see in my photo). CONCLUSION: KOM should include a small supply of Protective Tape - otherwise, this thing DOES NOT WORK for carbon seat post finishes - it just doesn't. Giving it three stars, up from just two. FIRST REVIEW: As others have reported, on a round, carbon seat post, it does not hold securely. I made sure the post was clean (with rubbing alcohol) before mounting and even with the "Boa" clamp as tight as possible, it seemed tight when I started the ride, but after 15 miles, on average pavement I noticed it had fallen almost three (3) inches. I had my doubts it was going to work, even before the ride because it was pretty easy to rotate/swivel the mount. Now, I'm sure KOM put this product out there and mostly didn't care. The rubber just isn't soft and grippy enough for smooth, round, carbon (matte finish) seat posts -- period. For $39, this single-function, basic accessory should do its job with no accommodations necessary. KOM, I'm going to try and make up for your indifference by wrapping my seat post with a piece of 3M protective tape, which I happen to have and which seems to want to grip you rubber insert a bit better than my seat post surface. I'll report back. If that works for me, I might keep your over-priced accessory.
