Great Great Great

This is the most amazing design and the product is a life saver! I recommend this product to everyone with a bike!

A great idea well executed.

The product is robust, works exactly as described, is super light and on the whole very easy to install. The only area I would say that needs improvement is the instructions on how to install if you have a thru-axle rather than a QR skewer. The combination of spacers is somewhat confusing and requires some trial and error.

AMAZING!!! Too many great words to describe it.

I'm a relatively new cyclist, been going at it for about 4-5 months now. Was looking for a rack system that would work on my Carbon road bike. Unfortunately my new purchase didn't have rack mounts.
Looked at some seat post rack options, but from reviews and looking at the product, they didn't seem reliable enough and and on the most important aspect they just didn't seem sturdy enough.
That is when I found the Tailfin racks and I can say I am 1000% satisfied and happy with the product. The rack system is extremely easy to install and works with no issues. I was hesitant at first because it seemed almost too easy and too simple, but it is the best product I have found and will be using it for a long time.

You barely feel the rack when it's on, and the SL bag attaches with ease and hovers on the rack like magic.

I currently use only 1 bag, so you can feel weight onto one side, but even that is very minimal and the bike still feels pretty balanced.
Just waiting for my 2nd bag to come in.

Yes, the rack is a little pricey, but it is well worth the money, without a doubt. The Customer service has been very responsive even to where I am located in California.

The only issue I had was with the instruction manual that comes with the rack and the explanation with the thru axle. It only has pictures, so it's quite complicated and confusing to understand(It's almost not needed).
I think I spent more time trying to decipher the manual then installing the rack. However, just watch the videos online/on this website and the install is super easy!!!

There are things that come close to perfect but this has hit the mark. I have 8 round trips of 40+ mile commuting to work. I have had a rear flat on one trip. No problem with getting the wheel off. I have had to stand and climb with no balance issues. I've lead a 26 mph paceline and at the end the comment was that's a beautiful rack. I have to carry two laptops and refused to put them on my back but disliked all racks on the market for my carbon bike, so I didn't ride. This rack is freedom.

Love it!

Enough room in the pannier for a small tent and some essentials, and attaches like a dream!
