THE ONLY BEARINGS DEVELOPED FOR SIDE LOADS Biltins are the first precision skateboard bearing developed to effectively handle the side loads caused by drifting, sliding, and high traction cornering. They were developed by World Cup Downhill champion Chris Chaput to meet the needs of the most demanding skaters. Having produced larger, high-traction wheels for years, Chris quickly realized the need to integrate both precision wheel cores and bearings to properly handle these intense side loads. The result is Biltin Bearings. Toss out your tiny washers and cheesy spacers. Biltin Bearings have integrated precision washers on the outside and two perfect half-spacers on the inside. You can tighten up the locknuts all the way and your wheels will spin straighter and faster than ever before. From a performance view, Biltin precision skateboard bearings are definitely built to last. There is an extremely tight feel between the bearings and the wheel. Ultimately, you will have a bearing set that will endure the demands of downhill racing or any demanding skateboard discipline. Sliding, griping and drifting especially benefit here with the need of these advanced bearing constructions. Trust Biltin precision bearings, you can feel the difference!
