Tool Box SeriesSmooth Dogbone Bit 7 in Cheek2 1/2in Purchase5 in ShankTBBIT37SS29The 7-1/2-inch cheek style is next in the lineup. Extremely versatile, this bit can be used for training drills, pleasure riding, or competition. This cheek has a 2-1/2-inch purchase with a 5-inch shank. The shank is swept back, like the 6-inch model, but to a lesser degree, which offers more leverage and control. When properly adjusted, it is still considered a mild cheek, but one with plenty of leverage for control at increased speeds. The Low Port Barrel is a highly universal bit that works well for anything from training to pleasure riding to competition. When engaged, the low port provides tongue relief as slight pressure is applied to the bars of the mouth and to the palate. Each side works independently from the port for increased lateral flexion.
