What shall I say. Finally I got rid of my heavy backpack when riding to work. The tailfin stuff arrived just in time before the Covid-19 crisis took really off. Now I can take along much more stuff to work (not just clothes and laptop but also food …) without any problem.
The bags are super solid and it does not feel like there is anything attached to the frame. No wiggle no shake nothing. Just perfect. Only when you go uphill you realise that there is some weight asking for more power.
Congratulations to this super product

I bought an S1 rack when they first came out and have been using it for commuting to work with an SL22 pannier. I wanted a second bag and ordered a UD22 since I'm not as concerned with weight on my steel commuter... ok it's a custom steel road bike, but hey life is too short to ride junky bikes. The UD22 is a perfect all around bag. I can fit my clothes, lunch and my laptop in the single bag, or I can use both bags when I have to carry more. Tailfin has been great with support even with my in the US and them in the UK. This stuff isn't cheap, but the quality, functionality and style won me over similar higher end bike bags and rack systems. Plus the ability to easily move the rack from bike to bike is the ultimate in future compatibility... once I have more time for some credit card weekend touring rides.
I bought 2 ultra-durable pannier bags. Very good quality!!!
Thanks for this great product!!!
