FSA announces Super Light headset bearings
FSA's new SL headset bearings use a clever hybrid steel and aluminum construction to shave a few grams
Weight weenies rejoice! FSA has figured out a way to shave a few grams from conventional steel headset bearings while retaining comparable levels of durability. As the exterior dimensions are unchanged, they're also a drop-in replacement for easy installation.
Weight savings are substantial in terms of percentages with the SL bearings as much as 38 percent lighter than conventional bearings, according to FSA. The reductions are more modest in terms of actual mass, however – just 7.7-9.2g depending on size.
FSA will offer the new SL bearings in 45° x 45° (for 1 1/8", 1 ¼", or 1 ½" steerer diameters) and 36° x 45° sizes (1 1/8" and 1 ½" steerers only). Retail price is US$29.99 apiece.
