hlins offers four different crown sets for DH38 suspension fork that differ in offset, allowing riders to further customize their ride. Offset is the distance between the wheel axle and the steerer tube and affects how the bike steers by changing the "trail" dimension. There are three different offsets: 46mm, 50mm, 54mm, and 58mm. Typically, shorter offsets are more stable but require more steering input to change direction. The opposite is true, too; the longer the offset, the easier it is to steer, but it will be less stable at speed. Most DH bikes with 29" wheels use 58mm and 54mm offset, while DH bikes with 27.5" front wheels use 46mm.Provides 46mm offset to DH38 suspension forksIncludes one lower crown with a straight 1.125" steerer tube pressed inIncludes two upper crowns; one flat, one drop crown Comes with two rubber fork bumpersM6 x 16 clamp boltsBlack Anodized Finish Ohlins DH38 Suspension Fork Crownset Crown/Steerer/Uppertube Assembly UPC: 840153633485
