CeramicSpeed OHD SLT Headset Bearing Kit Specialized Aetheos, Crux

he CeramicSpeed SLT (Solid Lubrication Technology) Bearing for Headsets: OHD (Optimized Headset Design), features a unique combination of an oil-encapsulated solid plastic polymer and stainless-steel materials which results in a self-lubricating, corrosion-resistant, and maintenance-free bearing. The micropores in the otherwise solid polymer evenly distribute just enough oil to keep the bearing well-lubricated, while also containing sufficient oil for it to be self-lubricating over the lifespan of the bearing – even when ridden in the harshest of conditions. The CeramicSpeed SLT OHD Bearing is designed, developed, and hand-built in Denmark and comes with a lifetime warranty. For more information about CeramicSpeed SLT bearings click here This kit contains 1 x 111820 and 1 x 111890 bearings.

Box Components Carbon 1-1/8 Inch Integrated Headset

There is more to our carbon headsets than their striking good looks. From top to bottom, Box One™ Carbon Headsets was designed to perform. Each unit features a custom CNC-machined aluminium compression cap in the shape of the Box logo with cut-outs to reduce weight. At the centre of the compression cap is an anodized aluminium bolt that threads into a gold anodized aluminium expander plug. This expander eliminates the need for a star nut and works with all 1-1/8-inch steerer tubes—even carbon fibre steerer tubes. The bearing cover is crafted from carbon fibre, which not only adds style but helps shave weight. And at the heart of the headset are two super-smooth, titanium-nitride coated, sealed, 45×45 bearings. The titanium coating results in a low friction coefficient, increased corrosion resistance, and smoother rolling bearings. A split crown race makes installation and removal from forks super easy.

Dia Compe IB-1 Integrated Headset

Durable sealed bearing headset using the most popular standard for Integrated headsets in BMX at the moment.*Note: Not all threadless headsets are the same! Diatech/Dia Compe is one of the very few companies authorised to use the Dia Compe USA/Cane Creek patented "split compression ring"Whilst this may appear a minor item... it actually has quite a significant effect in use. The split in the compression ring actually allows the ring to "grab" the fork steerer as the ring is compressed by the headset bearing adjustments. The "grabbing" prevents any possibility of "knocking" from play between the fork and the headset. Many other so called Ahead type headsets do not have this patented feature... even though, at first glance they appear to offer much the same performance. IMPORTANT NOTE: There are 3 main standards currently in use for Integrated headsets; They are all similar but NOT cross compatible... therefore check carefully which system your frame is made to accept.
