Products quality and assistance

I bought the first pannier rack years ago and I have been using it with great satisfaction on both road and gravel bikes. Recently I added a top bag to be ready for the ride Munich to Venice on a new E bike. I needed assistance in choosing the right Axle and that was provided very efficiently. Definitely a top-class company and products

L'attrezzatura Tailfin fa ormai parte del mio equipaggiamento più sicuro e leggero di cui non posso più fare a meno per le uscite in città o esplorazione! Spero un giorno, di poter far visita ai cari amici che hanno pensato con passione alla realizzazione di tutto questo. Grazie mille,

Stable Top loading Trunk beats a seat bag hands down !!!!!

Quick mounting Tailfin Trunk Top Bag is rugged and easy to load up with easy access to all of the needed clothing, waterproof jacket, food and cookware on a Bikepacking trip to the boonies. I also use it in town going to work - slipping in my iPad and a change of clothes and off in a flash. Great for a one day gravel adventure when the weather is unpredictable and you need to carry just a bit more. The whole unit is so stable you don’t know its there. Well done Tailfin for this ingenious piece of kit.
