Need bottles or accessories suitable for magnets, i.e. the “traditional” bottle itself is not suitable for these.
I've used over the next few weeks, the products in question with bottles bike ride. I do bike rides almost every day.
Mounting was easy. It is advisable to fasten with the supplied screws, as their base is lower (the original screws may have higher bases and thus affect the keeping of the bottles in place).
The bottles have stayed in place well, at least on the road, even as I drove over a few twigs and various bumps. The magnets are powerful and the bottles haven’t even managed to fall. It gets used quite quickly and as a result, the bottles start to find their place easily.
I think this is a good alternative to the “traditional” bottle rack. The only small minus the price, but I can also buy it with carbon fiber bottle racks and various Aero models, which are usually even more expensive.
Personally, I liked these.
Now it remains to be seen how they will last longer.
