Cero Helium Garmin Mount review

Cero is not the first brand to spring to mind when it comes to handlebar Garmin mounts, but it has done a good job here

Cycling Weekly Verdict

A great mount for a good price. Holds most if not all Garmin Edge computers securely without any bar slippage either. A small downside for those weight weenies, it is slightly heavier than other rival mounts.

    Heavy compared to rivals

With cycle computers now generally bigger in size compared to the old-school devices of 10 years ago, added to the fact that not everyone will use a 120mm stem or bigger, buying an out-front mount makes perfect sense to declutter your stem and handlebar area.

The Cero Helium is a good solution in a crowded market. It’s easy to fit with one bolt holding it in place on a 31.8mm sized handlebar. It’s designed to open while still attached on one side of the mount, which makes it easy to fit compared to two-bolt options. Two-bolt mounts can be fiddly to fit, often needing a third hand to hold it all in place!

The Cero Helium Garmin mount also doesn’t use extra pads or rubber strips to stop it slipping – it's all attached within the mount itself. On pretty bumpy potholed roads I experienced no slippage, even when using a slightly older and heavier Garmin Edge 810.

It’ll fit any Garmin Edge from a 200 right up to a 1000 (just about) and everything in between. The Cero Helium will allow the computer to sit flush with the stem not only in terms of stem to computer but computer to handlebar height too. It looks clean, but also allows space for lights etc on the handlebar; it also banishes stem mount and Shimano Di2 junction box issues too. Line of sight is good, like all other out-front mounts.

The mount does look good for the price – better than some slightly cheaper plastic models, though not as good as the more expensive CNC-machined offerings. It's also slightly heavier than many, at 33g compared to Garmin’s own (26g) or SRAM’s mount (20g).
