BUTTED SPOKES
All the Alpina spokes dimensions can be tailored to fit the different needs of the customer
SURFACE TREATMENTBlack E/D(cathodic electrodeposition)Black chromeBlack oxide
Single-butted spokes are thicker than normal at the hub end, then taper to a thinner section all the way to the threads. Single-butted spokes are not common, but are seen more and more in heavy-duty applications (for example E-bikes). Spokes are thicker at the ends than in the middle. Double-butted spokes do more than save weight. The thick ends make them as strong in the highly-stressed areas as straight-gauge spokes of the same thickness, but the thinner middle sections make the spokes effectively more elastic. Alpina spokes & nipples are produced with the exact thread-tolerance for durability and the highest level of quality.

THE FIRST AND ONLY SPOKE OF THE WORLDWITHOUT WINGS AND WITHOUT FILAMENTS.
After the absolute success of the patented ABS NIPPLES, Alpina Raggi has created a new product specially designed to improve the technical characteristics of your wheels. The perfect symmetry and geometry of its head, ensures a homogeneous and all-out distribution of the forces and of the loads, over the entire available surface in the underhead.
MAXIMUM STRESS RESISTANCE
MAXIMUM STRENGTH
MAXIMUM EFFORT AND DISTRIBUTION OF LOADS
As you can see in the 3d drawing made by our technicians, theabsence of wings, makes the spoke extremely resistant and indestructible to time and to the maximum stress.

HYPERLITE
The Alpina Hyper Lite is a light spoke, intended and produced by Alpina for the equipment of extra light wheels. Based on the 80 year’s experience of Alpina, the revolutionary HYPERLITE spoke is produced in AISI 304 PLUS & C45 CARBON STEEL.
Alpina Micro Wing is the latest brand new product developed and produced by Alpina. The under head wing measure of this spoke is extremely thin: max 0.04 mm / 0.00157 inches.The new spoke machineries projected and built in-house with a reinforced structure and close tool tolerances permitted our R&D department to create a spoke under-head wing with the minimal thickness actually in trade!This high-end technical innovation let this spoke become one of the most important and representative Alpina items.
The Alpina Super lite is a lighter spoke, intended and produced by Alpina for the equipment of extra light wheels. Based on the 80 year’s experience of Alpina, mainly in the “offroad framework”, the revolutionary SUPER LITE ULTRA spoke is produced in AISI304 PLUS, AISI 304, 302 and C45 CARBON STEEL a material that has completely replaced the stainless steel for its characteristics of cost effectiveness and major resistance to impact and fatigue.

SPECIAL NIPPLES
U.S.A. PATENT n° 6205664
EUROPEAN PATENT n° 838352
Self-locking, patented system, assuring highest functionality and reliability
Blue nylon shock-absorber insert, absorption ofmicro-vibrations to increase the durability of the spoke
Star spline improving the connection of the self locking insert
Spherical self-locking under-head
Traditional screw-driver cut for universal and standard use of the product
Gauged hole to obtain a perfect elastic interference with the thread part of the spoke
The raw nipple is cold-pressed with a control system for applied forces
The self-locking nipples assure long lasting centering of the wheel, safe braking, more comfort, and no need for maintenance
Exchangeability - immediately useable on any kind ofautomatic wheel building machinery, no need for anyregulation or modification of the standard applications.
The revolutionary self-locking patented nipple that, thanks to the nylon sphere inserted in its head, eliminates entirely thepossibility that nipples get loose on assembled wheels. Assembling routing between nipples and spokes remains absolutely alike to the traditional way and does not require special operations either for automatic assembling than for the hand-made one.
To prevent screw loosening the ABS nipple uses at its advantage the interference produced from the spokes thread during its screwing and the nylon sphere. It is possible to make subsequently all required adjustments on wheels without any special instructions and without using fastening liquids. ABS nipples bring tangible advantages on traditional wheels while their use is essential with straight head spokes.
ABS NIPPLES
The ending part of the threaded spoke “A” can come near to the nipple head, screwing itself together to coincide with the beginning part of the threaded nipple “B”, without never overcoming.
