great service and products

James arranged a custom part for my wifes Kouta Kathode E road bike to enable the through axle to fit. I can now fit my superb super light pannier sets to any of our bikes including my new pinarello Nytro E road bike for touring.
Great service and great products!
One improvement could be to make the inner cage on the superlight pannier lighter...... it seems a little over heavy construction....

très très satisfait de mon pack tailfin

Voilà près de deux ans que je roule avec mes sacoches tailfin et j en suis extrêmement satisfait. Le système de fixation est très bien pensé et les sacoches se fixent très facilement. Je ne vois aucun point négatif à relever et en plus le pack est esthétique. Franchement je recommande sans hésiter!!!!!!

Great product not sold in Japan

Design and functionality are good enough to overwhelm others and can only be found in tail fins. Also, the rack is lightweight with carbon is another good thing! There is no loss by winning.

Great product....unreliable delivery

The rack and the panniers have been superb.....both in use and in their weight (or lack of it)

Delays in recieving the products and then items from the same order arriving separately on different days was annoying

50 weeks of use and still as good as ever

I was one of Tailfin's original Kickstarter backers and I've never been disappointed with their products and their customer service. I've used my rack (white) and one pannier (I have two) everyday for the last 50 weeks for commuting to work, weekend shopping trips AND some bike packing. I've cycled through sun, rain, snow, hail, sleet and everything else that British weather has thrown at us this year. The rack is as strong and steady as ever, and I've moved it from my road bike to my hybrid and back several times. I've always locked it on with the extra bolts for the extra security but they only take a minute or two to unscrew and tighten again on my other bike. The panniers are completely water proof and they do NOT rattle. The locking system is simple but very effective. I've carried my laptop around many times, clipped lights to the back of the panniers and generally used one very, very thoroughly and apart from some dirt and the loss of some of the reflective detailing (1 stripe from the rear and two letters from the front) it's as good as ever.
I've been asked many times by admiring fellow cyclists about my rack and panniers and where I got them from. Tailfin is definitely recommended!
