When designing the Coast Stem we had two main goals: construct it to compliment the Coast Drop Bar and provide riders with an extra mount option for their gadgets. Along the way we ended up with one of the lightest stems on the market, keeping company with products four times its own price.

Get that footie or take a nighttime pedal. Each Coast Stem comes with a detachable mount compatible with many headlamp options, GoPros and other POV cameras.
sizing stats
When pairing this stem with the wide Coast Handlebars, shorter really is better. The shorter stem, in tandem with a comfortable 7° rise, places your body in an ideal position.

How Does Travel Adjust work?
Our travel adjust system allows for a total of 30mm travel reduction in 5mm increments. If you were riding that line between travel sizes you can now fine-tune the perfect fit by following the easy directions below:
- Begin by lowering your dropper at or below the desired travel length (just make sure it’s not fully extended!)
- Unthread the midcap with your hand and slide it up to reveal the white DU Bushing.
- You’ll see negative numbers with corresponding notches machined into the post (each # represents decreasing travel.
- Slide the DU bushing up and rotate it to align the black arrow with the amount of travel you would like to reduce, then seat the arrow into the machined groove. (Make sure it’s fit securely into these notches!)
- After pushing the DU Bushing back down, lower the midcap and hand tighten (no need to go overboard!) and ride off into the sunset with the perfect travel for you.

FAQ
Is there an option without the GoPro/light mount?
The short answer is no but the mount is easily removable if you don't want to use it!
Can I use the Coast Stem for mountain biking?
Yep! It's rated for mountain biking and is a great option for cross country bikes.
Which length is best for me?
Stem length is a heavily debated topic, and really comes down to personal preference. The key is to feel comfortable in the cockpit. If you are pairing this with the Coast Handlebar we recommend going down 10mm-20mm in stem length for every 20mm increase in bar width.

Reviews
Appreciate the slight rise on this stem. Very comfortable on long rides.

Ordered the 70mm and absolutely love it. The angle and length make riding on the hoods so much more enjoyable.

The stem provides good feeling while riding the bike. 7+_ degrees gives you a lot of comfort.
