Great product

Product installed easily and works very well. I'm very happy with it.

Brilliant on any bike

I borrowed a set from a friend and used them to carry everything I needed to cycle JOGLE on my own. They were superb through unexpected wind, rain and rough terrain. Lightweight, easy to attach and detach, waterproof, plus a low centre of gravity which doesn't alter the handling of the bike too much. I now own a set of my own plus I've bought an extra axle for my gravel bike so that I can switch from one to the other.

Tailfin T1 & SL package

I've only unboxed and had a trial fit so far, so yet to use in anger, but I'm very impressed with the quality of the products. They're beautifully engineered, very lightweight and very simple to fix to my Giant Defy carbon bike. Impressed so far ....

Mooi , goede koop!

Was al een hele tijd opzoek naar een drager voor mijn BMC Roadmachine 02 maar kon niets vinden dat geschikt was. Afgelopen jaar een paar weken in Frankrijk een aantal collen bedwongen met een rugzak van 7.5 KG , in de Alpen en de Elzas.Geen pretje... Nu aan het trainen met de de Tailfinn set . Werkt hartstikke goed. Klimmen in Zuid Limburg en Berg en Dal en op zondag met volle tassen ( ca 2x 4.5KG) met mijn ploegje mee:allemaal geen enkel probleem. De flex in het frame zit er nog steeds: ik was bang dat het star zou worden maar door de de bevestiging op de (nieuwe) steekas ontstaat er toch voldoende flex zonder dat het slap wordt. Tassen klapperen niet, zitten zeer strak tegen de carbon drager. Geen hakken tegen de tassen door de iet wat gedraaide constructie. De bevestiging aan de zadelpen was even zoeken: BMC heeft een D vormige zadelpen waarbij het Tailfinn beugeltje niet te vast mag zitten. Ik heb het verbogen maar naar een paar dagen lag er el een nieuwe in de brievenbus! Goed opgelost, maar wellicht een klein verbeter punt. Prijs is stevig maar je krijgt er wel een mooie oplossing voor terug. Ben benieuwd hoe ze er na een lange fietsvakantie uitzien. 5 jaar garantie geeft wel vertrouwen!


Perfect for my commute on a carbon bike. Blends in with look of bike and doesn’t affect the ride, easily installed and is just perfect for my needs. No more rucksack 👍. Little costly but like I said already.....just perfect
