Really great. Light, sturdy, quiet

My tailfin rack is the best thing I've ever done for my 16mile ride to work. It's light, sturdy, quiet, and has plenty of room. It's also easy to install and remove when needed. Can't wait for the trunk bag to get here!

Beauty in simplicity

I'm in the midst of doing the reverse of N+1 and undergoing "Project One Bike". To be fair, there are 3 different wheelsets. : ) Part of this project meant finding a rapid on/off system for bags so that I could pack clothes, food, gear, computer into work and then just as rapidly convert it back to "just a bike" for a hard session after work. Three weeks in and very happy with the performance. I develop digital products and immensely enjoy an intuitive, seamless experience and the tailfin absolutely delivers on this front. Furthermore it's functionality is paired with a minimal sleek look. Thanks for a really great option and can't wait to see what you come up with next.

Excellent mechanical design

I’m a mechanical engineer who works in aerospace and I appreciate well engineered designs that maximize stiffness and strength, while minimizing mass. I thought that the design and innovation of this rack and pannier were excellent. I was very impressed with the design and workmanship. The installation was simple, the design is sound, and the assembly and mechanisms work great. I’ve been using the rack for about 2 weeks for my 12 mile commute, and I’m very happy w my purchase.

I liked the first product.

자전거 캠핑을 위해 제품을 구입했습니다. 가격이 부담스러웠지만 가볍고 튼튼한걸 구입 했습니다.
저번주 주말에 130km 달려 하루 캠핑을 했고, 언덕을 내려 올때 시속 50km/h를 달성 했지만, 테일핀은 흔들리지 않고 안전하게 달려있었다.
각각 22L용량의 가방에 캠핑 장비와 음식을 넣을 수 있었다. 발포매트는 가방 위에 고정 시켜서 달아놨다.

I bought the product for bike camping. I bought a light and sturdy but the price was burdensome.
We went for 130km on the weekend last weekend, camped for the day, and when we came down the hill we achieved 50km / h, but the tailpin was running safely and steadily.
We were able to put camping equipment and food into each bag of 22L capacity. The foam mats were fixed on the bag.

A beautiful product. I used on 5 day / 650km tour across Switzerland (+neighbors). Through cold and warm, sun and rain, flat and steep long climbs, they worked perfectly.

I found a solution to carry the bags when not on the bike (as others mentioned the carrying straps are not very practical) — simply turn both bags on their side and use the packing tethers as handles. It is very simple, comfortable and convenient.

Nick - you need to used facebook marketing! I had to search to find these existed. Quad-lock (another great product) showed up constantly in my feed as a biker. Also I would suggest you proactively send samples to boutique bike shops as they will love them. You will get a call from one i showed mine to on my trip!
