The headset bearing code AC3344 (33x44x6) is typically used in integrated headsets and is a common size for frames with a 1.5″ or tapered head tube (usually 44mm external diameter at the base and 33mm at the top). This size is frequently found on:

• Mountain bikes (MTBs), especially those with tapered steering tubes.
• Some fat bikes and enduro bikes that use a more robust design.
• Gravel bikes or certain hybrid bikes that use a sturdier headset for increased durability.

This bearing size provides a secure and smooth interface for the fork, typically seen in modern frames that prioritize stiffness and strength in the front end.

The AC3344 (33x44x6) headset bearing size is common across several popular bicycle brands, especially those focused on mountain biking, enduro, and even some gravel bikes. Here are some brands and frame types that often use this headset standard:

1. Specialized

• Specialized Stumpjumper (modern models)
• Specialized Enduro
• Specialized Fuse (for larger forks and beefy geometry)

2. Trek

• Trek Fuel EX (recent models)
• Trek Slash (enduro models)
• Trek Remedy (mountain bikes)

3. Canyon

4. Santa Cruz

9. Cotic

10. Commencal

Many of these brands use the tapered headset standard (44mm lower and 33mm upper) to offer greater stiffness and strength in the front triangle of the frame. Be sure to check the exact model year and frame specs, as some brands may have used different headset standards in earlier years or on specific models.
