## Description

desertcart.com : Funn Descend Upper Headset ZS56/28.6, Zero Stack Angular Contact Bearing Upper Headset for Mountain, BMX, Road & Gravel Bikes : Sports & Outdoors

Review: Instantly eliminated "play." Smooth as butter on my Axum - After adding new stem and handlebars to a Schwinn Axum DP, I couldn't get the front end dialed in. The stem had play (wiggle). The only way to eliminate it was by tightening the top bolt down so hard the fork could hardly move. After forums, YouTube videos, and lots of tinkering I decided to just purchase this. Instant fix. It's high quality, easy to install even without the headset tools. I used a screw driver to pop the old cup out, some grease, piece of wood, and rubber mallet to gently hammer the new one in. Greased the cup, set it in, put towel over it, wood in top, tapped the wood to insert the cup. Wipe away grease, install everything back to proper place and bang, better than new. Instantly. 5 stars.
Review: Best value Headset on the Market. - Perfect zero play headset. No creaks or wobbles, light and tight and perfect movement. No need to go ridiculous cheap, by the Funn setup and have satisfaction knowing it’s as good as $90 dollar headsets from expensive brands.

## Questions & Answers

**Q: How do I know what size of Descend headset I need?**
A: Measure the outer diameter of the fork's steerer tube and the inner diameter of the frame's headtube to determine the compatible specification for our Descend headset.

**Q: What is the bearing type of Descend?**
A: It's built in high-quality angular contact cartridge bearings.

**Q: How do I know if the headset is too tight or too loose?**
A: For a proper fit, the handlebars should swivel smoothly without binding. A too-tight headset restricts turning, while a too-loose one can lead to knocking or rattling.

**Q: How often should I service or clean the Descend headset?**
A: It's recommended to do it once a year or every 3,000 miles (5,000 km). Of course, this can vary based on your riding style and the conditions you encounter.
