The Peak Design Out Front Bike Mount is designed for all types of cycling, from hardcore road and mountain biking to commuting and recreational riding. Compared to our Universal Bar Mount, the Out Front mount is better for scenarios where rigidity and security is of the essence.

Supported Handlebar Sizes

The Out Front mount includes 3 sets of sizing collars, designed to rigidly and securely attach to the the most common bike handlebar sizes:

• 22.2mm (7/8")
• 25.4mm (1")
• 31.8mm (1-1/4")

These sizing collars cover a vast majority of road and city bikes, and many mountain bikes.

The Out Front Bike Mount is not compatible with the following bar types:

• 35mm bars, found on some newer mountain bikes
• tapered bars (though workarounds are possible—see below)
• non-round bars, like aerobars

For these bar types, we recommend the Universal Bar Mount, but with some caveats (see below).

Why Didn't We Support 35mm Bars?

Some recent mountain bike manufacturers are shifting to 35mm bars that taper down to a smaller diameter just outside of the stem. At the time of of designing the Out Front Bike Mount, we consciously opted not to support 35mm bars. We did this because we aimed to achieve a balance of strength and svelte-ness that was optimized for road cycling and commuting.

We made this tradeoff because, after reviewing our own habits as well as conducting research with customers, beta testers, and bike retailers, it became clear that road/commuter cyclists are far more likely to use their phone while riding.

As more bike makers switch to 35mm bars, and as word about Peak Design's Mobile ecosystem continues to spread through the world of cycling, it has become clear to us that supporting 35mm bars is a growing priority. We're currently looking into options for modifying our current Out Front mount, and/or introducing additional bike mounts into our ecosystem.

Options For Bikes With 35mm Bars Or Aerobars

Currently our best phone mounting option for 35mm bars is the Universal Bar Mount. It uses a silicone band to attach to any size/shape of bar. It can also attach to your bike's stem or even frame. Plus, you can quickly remove it to prevent theft, or to relocate it to another bike you have. It even works on strollers, grocery carts, and nearly anything else with a handlebar.

The big caveat is that the Universal Bar Mount does not rigidly clamp to your bike. It's plenty secure for road and even light gravel/trail use. But for bumpy, hardcore mountain biking it's not ideal, as the mount could shift position on your bars when you hit particularly gnarly terrain.

Options For Bikes With Tapered Bars

The Out Front mount is not designed to be used with tapered bars, but with a bit of hacking you can (often times but not always) make it work. A number of folks on our team, as well as our beta test group, have tried this method with success.

First, grab some electrical tape. Identify where on your bar you'd like to install the mount and find the closest sizing collar to that area. Place a few wraps of electrical tape around the handlebar to build up the smaller section of the taper, and then install the Out Front mount over the tape.

You may need to try a few iterations of this before you get a secure mount. And if you ride or store your bike in the heat, or you go over a lot of rough terrain, you may eventually need to pull the tape off and re-wrap.

It's not the prettiest solution, but it may work for you. Internally we've got units mounted with this method that are still going strong after a year and hundreds of miles of use.

If you don't want to go the tape route, you may also have luck with the aforementioned Universal Bar Mount.
