Sapim "Double Square Polyax Brass" Spoke Nipple

The Sapim "Double Square Polyax Brass" Spoke Nipple has no slot but a square drive at the top and the bottom: Sapim developed it for the Holland Mechanics wheel building robots, it is driven with the Sapim nipple driver from the rim bed side or with the straight nipple driver from the inside. Without a slot the head takes more torque, and coloured nipples stay scratch free during lacing. The head is the Polyax round head that works like a ball joint between rim and nipple. The length is the overall length of the nipple, the threaded part measures 12 mm (16 mm nipple) or 14 mm (18 mm nipple). Brass is the most common nipple material: Sapim nickel-plates it for very good corrosion resistance, it is robust and the first choice for wheel building machines. A brass nipple weighs around 0.9 g (manufacturer: 60 g per 64 pieces). Sapim is a Belgian manufacturer that has built nothing but spokes and nipples since 1918; the Polyax has been around since 1995. Notes: 1. The right quantity: this nipple is sold individually, so please choose the quantity in your cart. A BMX wheel usually has 36 holes, an MTB wheel usually 32, and newer MTB wheels often 28 at the front and 32 at the rear. A few spare nipples are always a good idea. 2. The right length: which length suits your rim depends on the rim bed, eyelets and spoke length. If in doubt, ask us and we will work it out with you. 3. Matching parts: the nipple fits every spoke with a 2.0 mm thread (14G), i.e. Sapim Leader, Race, Strong, Sprint, D-Light, Laser, CX-Ray and CX-Sprint. For spokes with a 1.8 mm thread (15G, Sapim Super Spoke and CX-Super) there is the Polyax Alu 15G.
