ROK IZRADE I ISPORUKE: 7-15 DANA
Stiff and light enough to race and ride daily
Imajući na umu vrhunske performanse kao prvi prioritet prilikom izrade kotača, ova vrsta Bellani obruča izrađena je od visokokvalitetnih UD T800 karbonskih vlakana, izrezanih u različitim smjerovima i složenih u slojeve. Unutarnji otvor obruča dodatno je presvučen tkaninom od karbonskih vlakana (3K Net, 1x1, 210g/m2), koja djeluje kao armatura unutar samog obruča, dodajući dodatnu razinu krutosti i apsorpcije udaraca.
- Obruči unutarnje širine 30mm (35mm vanjske širine), držati će vas čvrsto i stabilno u zavojima na bilo kojoj XCO, XCM ili Trail stazi
- U kombinaciji sa Bellani XCM 220 glavčinama, Sapim CX-Ray žbicama i aluminijskim niplama, težina kompleta kotača iznosi 1285g
- Obruč ima asimetričan profil, što pridonosi krutosti obruča i boljoj raspodjeli naprezanja prilikom slaganja kotača
- Visina obruča iznosi 25 mm, što je više od ostalih naplataka na tržištu, koji se nalaze u SuperLight kategoriji, dok veći naplatak znači bolju otpornost na udarce
- Dizajn sa niplama smještenima s unutarnje strane obruca zahtijeva manju rupu za žbice, što znači da je manje vlakana 'unisteno' prilikom busenja rupe, što obruč čini čvršćim i izdržljivijim, što doprinosi boljem aeroprofilu i vrhunskom dizajnu
- Dodatno ojačanje Black 3K NET daje uravnoteženiju raspodjelu napetosti unutar strukture obruca te vecu krutost, što rezultira boljim performansama na stazi

Due to the high cost of the rim customization we do, the outcome price of the rim in production is very high.
In order to keep the wheelset price low as possible, we had to produce high quality hubs that can match the quality of other high brand hubs, like DT Swiss. The cartridge of the hubs have been CNC custom machined with internal design to support classic Ratchet system with our Convex/Concave Ratchet or latest DT Swiss EXP Ratchet. Later one have been used for our test drivers.
Using quality materials for the hub cartridges like 6061 T6, 6082 T6 and/or 7075 T6, and precise CNC machining, we managed to produce high quality hubs at the acceptable price, and thus keeping the wheel set price more affordable then the other carbon fiber wheels sets on the market.
Stealth Black Series
Combining high-grade carbon fiber T800, right curing time, temperature and pressure inside the mold, gave us one of the lightest rims you can find on the market, with moderated stiffness providing control and comfort during long XC marathon races.
Internal nipple design demands smaller holes in rim structure, which means less carbon fiber strings been disrupted, boosting the stiffness and durability of the rim. This Bellani rim is one of the lightest you can find on the market, respecting the height and width of the rim profile, and inner nipple design at the same time. Being light and stiff, it is still proportionally elastic in order to moderate all impacts while driving over rocky and steep descents.
One of the lightest rims you can find on the market, with a great impact resistance.
Black NET Series
Having a performance in mind as a first priority, this type of Bellani rim is made out of the High-Grade UD carbon fiber T800 and T1000, cut in different directions and layered up together. Inner hole of the rim has been additionally layered with the carbon fiber sheet (3K Net, 1x1, 210g/m2), acting as reinforcement tube inside the rim itself.
Additional reinforcement defines new level of stiffness, but also adding to a rim weight as well. So, in order to stay in SL weight class, we had to use high ratio of T1000 UD for the rest of the rim structure. Internal nipple design demands smaller holes in rim structure, which means less carbon fiber strings been disrupted, boosting the stiffness and durability of the rim.
Every watt you put to the pedal, will be transferred right to the ground.
Internal nipples means stiffer rim, great design and aero profile
Every spoke hole of the rim is the weakest point of the rim structure. Regular carbon fiber rims on the market have a spoke hole that is 4.5~4.7 mm wide. In order to mitigate this structural impact, we have decided to use concept of the small spoke holes 2.3mm wide.
This makes a rim stronger, due to the less carbon strings are being disrupted, but also gives a more fluent design and aero profile while keeping nipples 'hidden' inside of the rim.
Of course, all those benefits comes with a weight penalty of having additionally 15g per rim. Due to the fact of having smaller hole in the place where the rim is the thickest, the rim weight raised up for about 15g per rim, or even more.
But nevertheless, even with this weight penalty, every Bellani rim you go with, will be one of the lightest you can find on the market. All this tells about the High Carbon Grade fiber we are using in order to mitigate all those challenges.
Smart Tubeless design
Every Bellani rim is a tubeless ready by design, by applying hookless rim design. Following this design given on the right, there are two important details 'rim bead lock' and 'rim bead seat'.
