The Sentry Bar is part of Tilt’s Stage II collection which features backsweep and upsweep for added comfort with large bar sizes. A 3D formed steer tube featuring the Tilt logo smooths out the welded areas decreasing knee and chin hits, and the heat treating process significantly improves strength. You'll be stoked to hear that Sentry Bars are Thrash Resistant - A lifetime guarantee against bends and cracks. Get psyched.
