MUKILTEO, WA (BRAIN) — FSA's new Super Light ACB Bearings are up to 38 percent lighter than its standard headset bearings, saving up to 9.2 grams per bearing with no loss in durability, the company said.
The new SL Bearings have the same chrome steel inner / outer races and balls as standard FSA headset cartridge bearings. But the new bearings have a Hybrid Alloy Housing instead of steel. The drop-in replacements retail for $29.99. They are available in 45º x 45º and 36º x 45º combinations.
