great rack

expensive (hence 4 stars) but there's nothing else as light or easy to fit to a carbon road bike

S Three Trunk Rack

I bought an S Three Trunk Rack and an AP20 Trunk Top Bag and I am fully satisfied. I used my new bikepacking system for two 5 day dirt touring routes and found it to be a more efficient and stable system compared to the seat bags. The system is very practical when travelling by train or sleeping in a hotel. The engineers and designers at Tailfin have made life easier for us bikepackers. Congratulations!

Aero pack

I simply can not fault this product. Fit and remove the pack and arch in seconds. It’s well made, light, attention to detail in its design is superb. 9/10, loses 1 point as it’s a little pricey.

Solid Rack

Extremely rigid yet aesthetically pleasing. I love the configurability having one or two panniers or cargo cages. I was able to take it out on its first overnight test run and it performed flawlessly. Connection points are strong and robust and the fit and finish on the hardware is excellent. Worked great!
