At 53 mm The Classic Front Load, or CFL for short is the longest stem we make. The CFL still uses the 6 bolt configuration, but the bolts enter in the front. This style is popular for adjustment and installation because the bolts are not hindered by the bars or being underneath. Typically run “drop” style, where the bars are lower than the center of the stem, you can run it either drop or “riser” style, where the bars are higher than the center of the stem. Both Classic Stems fit on any 1/18 fork, and can be run either side up, and NEVER require spacers to clear the frame, that would just be silly.
A Handlebar stem, sometimes referred to as a neck, is a clamping device that holds a handlebar in perpendicular arrangement to a fork. These three pieces, working together with a headset attached to a bicycle frame, are your steering system. The stem can either be Quilled or shafted or Threadless. Threadless stems are one of the most important cycling innovations to effect BMX. There is no respectable bike made in the last decade that doesn’t use a threadless stem. The typical threadless stem is an aluminium unit that holds the bars with almost infinite adjustment front to back and side to side. While the side to side is usually adjusted to parallel to the front wheel and frame, the front to back is arguably the most important adjustment on any bicycle. It is where you hold onto the bike, and is entirely personal.
