Through the spherical contact surface, DT Pro Head nipples align automatically with the angle of the spoke, which leads to a homogeneous power transmission. The special shape of the head prevents the nipple of tilting in the rim base, which is a great advantage for wheel building.

• Can be used in place of alloy Squorx Pro Head nipples when building DT rims that require Prohead nipples and washers (PHR washer is still required)
• 32 nipples weigh approximately 30 grams
• ProLock nipples contain a special adhesive compond which is activated when a spoke is threaded into the nipple, forming a durable bond
