Description
Autobahn Dual Duro A/T Formula 55mm 99A White Wheels pair Autobahn's Dual Duro A/T Formula with the Dual Duro shape, in 55mm x 32mm.
Dual Duro wheels are, in Autobahn's words, the most technical wheels it makes. A hard polyurethane core is wrapped in a slightly softer layer, which improves the bearing seat and combines the speed and response of a hard wheel with the control and comfort of a softer one. The A/T (All Terrain) formula performs reliably across different surfaces.
Who These Wheels Are For
- Technical street skaters
- Skaters who want hard-wheel speed with more control
- Riders who want a smoother ride without losing slide

- Autobahn Dual Duro A/T Formula, 99A
- Dual Duro Density construction: hard core, softer outer layer
- 55mm x 32mm with a 18mm contact patch
- White
- Set of 4
Benefits
- Hard-wheel speed and response
- Extra control and comfort
- Improved bearing seat

Complete Your Setup
Wheels don't include bearings. Bronson makes three tiers:
- Bronson G2 Bearings (Good): the entry point to Bronson bearings.
- Bronson G3 Bearings (Better): a step up for street, park, and transition.
- Bronson Raw Bearings (Best): Bronson's top-tier, shieldless bearing for fast rolling and easy cleaning.
FAQ
Is 99A hard or soft?
Hard and fast on smooth street and park surfaces.
What is a dual durometer wheel?
A wheel made with two urethanes: a hard core wrapped in a slightly softer outer layer. Autobahn says it combines the speed and response of a hard wheel with the control and comfort of a softer one.
What size wheels should I get?
Smaller wheels (50 to 52mm) are light and technical, 53 to 54mm is the street and park go-to, and 55mm and up adds speed for transition and rough ground. See our skateboard wheels guide.
Do these wheels come with bearings?
No. Wheels are sold as a set of 4. See Complete Your Setup for bearings.
