Wolf Tooth is always tinkering with products to make your bike more customizable to fit your needs. Their newest product is these lower headset cup extenders, allowing you to adjust the effective geo of your bike by increasing thee axle-to-crown length by 10mm. When dropping one of these in the lower head tube cup, it will allow you to do things like use a rigid fork on a suspension-corrected frame or use a fork that might have a lower ATC than the bike was designed for. Or drop one on your current bike and lower your head angle and raise your bottom bracket.

These are made in the USA, available in black, blue, or red, and in-stock now at Wolf Tooth.
