Fits diverge comp carbon

Bought as a spare while i have my oem clamp color matched to my bicycle accent color. Diverge comp carbon specifies 30.8mm, this is 30.6mm and fits fine. Also opens up the possibility of using a rear rack eventually since the frame does not have eyelets for racks on the seat stay.

Bom custo x benefício

Abraçadeira de ótima qualidade, por um preço melhor que as concorrência de qualidade similar (se comparada com a Shimano PRO, por exemplo). Além de ter um bom preço, qualidade superior, um design agradável, tem uma ótima funcionalidade para os cicloviajantes: ser compatível com alguns modelos de bagageiros. Só tem um contra: pra quem vai utilizar em bicicletas com pneus traseiros com mais cravos, geralmente muita sujeita é jogada na região da abraçadeira do canote de selim. Por este modelo ser maior (mais robustez por conta da compatibilidade com o bagageiro), acumula uma quantidade considerável de sujeira. Se isso é algo que incomoda, melhor optar pelos modelos menores.

Great option for attaching a Tumbleweed rack to my Diverge. Only issue I ran into was the bolts that came with the rack were too long to go into the collar and I had to purchase bolts that were shorter.

This product does just what

This product does just what it is supposed to do - make it easy to attach a rack to my carbon frame that has no built it lugs. One important tip: be sure to grease the rack bolts and do not tighten beyond the recommended 6NM. I made that mistake with my first one and ended up snapping a bolt off when trying to remove it and had to buy and install a new collar.

Does exactly what it is supposed to, allowed me to mount my rack. Does not come with the necessary bolts, so be sure to pick those up at your bike shop as well.

It's cool that you can

It's cool that you can run a rear rack on the Diverge, but I get a bad squeak from where the rack (aluminum) connects to the frame (carbon). The squeak only goes away when I have weight (loaded panniers) on the rack. Kind of a bummer, but still cool that you can run a rack on the Diverge.

This works exactly as it should. Be sure to get the correct size rack -- I didn't realize they came in 2 sizes and mistakenly ordered the one with arms that were too long. Haven't been able to get them swapped yet.

Works well.

Great way to attach rack. Note that the clamp tightens with an allen wrench. Then you use screws to attach rack supports.
