The CrankTank 4 is a great hydration solution for my bike packing adventures. With the frame adapters it fits very snugly on my Lynskey Elysium gravel bike.

Je suis assez déçu, au premier remplissage en me préparant à partir en voyage, le bouchon fuit!! La jonction entre l’orifice pour boire et le reste du bouchon sont mal collé… je m’attendais à plus de rigueur.
De plus, en visionnant les photos du produit sur le site, je constate que les petites cales évitant le cranktank de frotter directement sur le cadre ne sont pas fourni ! Je vais devoir bricoler quelque chose, se qui n’est pas normal quand on paye un produit à ce prix!
Sinon le corps du tank semble de bonne qualité.

Have not used it yet on tour, but I like it. It fit just fine in the, um, "crotch" of the triangle. I will probably pass on the adapters as it sits lower without them and just wrap some old bar tape around the frame to prevent abrasion. I was doubtful that it held the claimed four liters, and then I dumped out four liters of water from it! My only concern is that the pressure release valve is not protected from dust or debris and so I am not sure how to prevent the water from being contaminated. Only that prevents a five star rating. If you tour, you need this. Just buy it. (I had four containers to carry four liters, now I only have one.) Oh, for SIX stars, insulate it so that it will keep ice for a full 8 hours. (I had mounted a 2L stainless steel insulated jug on my seat tube. Hmmm. Will it fit above the CrankTank?)
