Cyclists know that lighter is better, every gram saved means more speed and that means everything. The epitome of weight savings comes from carbon fiber, with ingenious layups that shave weight without sacrificing strength or durability. When it comes to carbon forks and especially steerer's you need something special to tie your frame and headset together, an Expansion Plug rather than a traditional starfangled-nut. The GWH Industries Expansion Plug features a knurled design that binds with the carbon steerer, and works exceptionally well with installation epoxy. The Expansion Plug features a four-piece design that provides a secure hold inside the steerer tube. It also includes a headset Carbon Top Cap and bolt to complete the installation on your new whip.
