Perfect fit, amazing quality ! Five star when the extender will be available.
For my daily commuter ride the tailfin is brilliant! Lovely design, quick mounting, and the bag releases very quickly from the frame and catches all the spray of the backwheel ✌️My heaviest load has been 3kg op potatoes, 1kg apples and 1kg tomatoes, which was fine! Haha 😎
Happy with the all alloy X Three model for commuting and looking good without bags on. Eyelet mount configuration fit over existing fender hardware nicely and the third party pannier adaptors fit *insert popular name brand here* panniers great. Only issue was with setup when the U of the top stay near seat post attachment bent, this section is pretty thin so take care when mounting but does not see significant stress during use. Top stay will be slanted upward slightly on larger frame bikes but can be strapped below seat post collar if frame geo allows for it.
