2 Start with spoke closest to tire valve stem and tighten each nipple, in sequence, exactly 1⁄4 to 1⁄2 turn. A single 1⁄4 to 1⁄2 turn may not be enough to bring the spokes into proper tension. Continue tightening all spokes no more than 1⁄2 turn in sequence until all spokes

are tight.

Note: Tightening each nipple more than a 1⁄2 turn each can cause the wheel to become distorted and wobbly thus permanently damaging the wheel.
