Custom OEM Titanium Spoke Nipples Manufacturer & Factory in the Zadar Market

We manufacture titanium spoke nipples across all international wheelbuilding standards. Standard bicycle gauges include 14G (diameter 2.0 mm, thread pitch 56 TPI according to DIN 79012), 15G (1.8 mm, 62 TPI), and heavy-duty 13G (2.3 mm, 56 TPI for electric cargo and e-MTB platforms). Standard lengths include 12 mm, 14 mm, 16 mm, and extended 18 mm nipples for deep-section aerodynamic carbon rims. In addition, we produce inverted hidden internal nipples (driven by Torx T20 or square sockets) and spherical-head nipples engineered for directional rim drillings. Custom technical drawings (STEP, IGES, or PDF) are quoted within 4 hours.

Aluminum nipples (predominantly 7075-T6 or 6061-T6) seize due to two simultaneous degradation mechanisms: galvanic corrosion against stainless steel spokes and pitting corrosion triggered by chloride ion intrusion. In Zadar’s saline coastal environment, moisture bridges the gap between the spoke thread and nipple, triggering galvanic oxidation that fuses the threads together within 6 to 12 months. Grade 5 titanium possesses a natural dielectric passivation layer ($TiO_2$) that exhibits an inert electrochemical potential relative to AISI 302/304 stainless steel spokes. When assembled with a quality anti-seize paste, titanium threads will never corrode, seize, or weld, allowing wheels to be trued and rebuilt indefinitely.

Titanium has a known propensity for thread galling when tightened dry under high friction. For professional wheel lacing, we mandate the application of a high-pressure titanium-specific anti-seize compound (containing copper flakes, graphite, or synthetic fluoropolymers) or a specialized thread prep compound such as DT Swiss Spoke Freeze or Wheelsmith Spoke Prep. These lubricants create a micro-barrier that prevents metal-to-metal galling during high-tension truing (1200–1400 N) while preserving thread integrity against vibrational backing-out on rugged karst descents.

As Croatia is an EU member state, all shipments entering Zadar require standard customs declaration under the Common Customs Tariff (TARIC). Titanium spoke nipples are typically classified under TARIC code 8714.99.90.90 (Parts and accessories of bicycles) or 8108.90.90 (Other articles of titanium). Velnora provides complete commercial invoices, packing lists with net/gross weights, certificates of origin, and EN 10204 3.1 material test certificates. Shipments can be routed via express couriers (DHL Express, FedEx, UPS) directly to your Zadar facility with DDP (Delivered Duty Paid) or DAP terms, taking approximately 4 to 7 business days from dispatch.

For standard 14G spoke nipples in raw polished finish, our minimum order quantity starts as low as 100 to 200 pieces, enabling boutique wheelbuilders to assemble multiple wheelsets without tying up capital. For custom CNC designs (e.g., proprietary inverted spline heads, custom internal Torx broaching, or specific lengths outside the standard catalog), MOQs range from 500 to 1,000 pieces per specification. Electrochemical anodizing (Gold, Royal Blue, Violet, Green, Bronze, Raw Matte) is available in small batch runs starting at 200 pieces per shade.

Every batch of raw bar stock sourced at our Baoji facility undergoes chemical spectrometry testing to verify accurate titanium, aluminum (5.5–6.75%), and vanadium (3.5–4.5%) contents, guaranteeing genuine Grade 5 structural integrity. During Swiss-turn production, our threads are cold-rolled rather than cut whenever geometrically feasible. Cold-rolling rearranges the titanium grain structure along the thread contours, enhancing grain density and surface hardness by up to 25% while achieving smooth Ra 0.4 surface finishes that eliminate thread micro-burrs and premature stripping.
