Frequently Asked Questions

Bar Fly has created several mounts for most major cycling computer brands. We have Garmin and Wahoo available in our shop. For other available styles, visit Bar Fly.

Due to the wide variety of shapes & construction techniques of this type of handlebar, Route Werks does not recommend our products to be used on carbon fiber handlebars. Such use is done at the user's risk, and Route Werks is not responsible for any damage or injury to person or property resulting from such use.

Due to frame size, component pairings, and placement, we may not fit certain bikes. Our Bag fits most bikes with a rigid fork, round, 31.8mm diameter handlebars (25.4 & 26.0mm w/ adapters, sold separately), 50.5mm - 69.5mm of available clamping space, and at least 170mm of clearance from the top of the handlebar to top of the front wheel.

The short answer is no. Our bags are made of durable, water-repellent materials to protect your essentials. However, these bags are sewn goods, which keeps us from saying they’re completely waterproof. We recommend using a small dry bag if you are taking something that cannot get wet.

Such use will typically damage the Handlebar Stub's anti-rotation feature. We do not recommend using such a setup and any usage of this type will void the warranty.

In most of our testing, we found that the narrowest drop bar that will accommodate a Handlebar Stub is a 38cm bar. This can vary based on bike setup, preferred hand position, accessory size, plus numerous other factors.

The Handlebar Stub is 31.8mm in diameter.
