4MX crowns are 66% lighter than steel. Made of CNC with extremely narrow tolerances. Specially improved aluminum alloy 7075 T6 high strength. Computerized Ultralight ™ design offers maximum reduction of non-suspended masses to the rear wheel to ensure maximum power transfer. Self-cleaning mud flutes between each tooth on both sides prevent accumulation of dirt.24,00 € VAT included
The Chiaravalli group has been producing gear wheels for over 50 years. The high quality of the materials used, the production technology and the stringent quality controls that each product individually undergoes have made CHT material over the years a quality reference in the industry. All off-road ergal crowns are made of aeronautical aluminum 7075T6 (Ergal), lightened with round holes and unloaded at the bottom of the tooth to ensure a perfect discharge of mud and ensure better durability over time. The crowns are supplied in silver or colored anodized to ensure greater surface hardness, better corrosion resistance and aesthetic finish with maximum impact.
The GP-Twin crowns are produced using an anodised aluminum stem and an outer steel ring treated. The particular triangular discharge profile of the inner stem, as well as giving a racing look to the bike, allows to hold the weight (about 600 grams complete) and at the same time to have a higher stiffness. The outer ring is made with a black protective coating that increases surface hardness. GP-Twin crowns are the ultimate combination of durability, lightness and price!54,50 € VAT included
Power Racing crowns are a high-quality, 7075-T6 aluminum extremely lightweight. It uses an exclusive bottom dental design that provides 24% more contact area on the power transfer chain in the best possible way It also has a hard oxidation coating over any other aluminum crown on the market for longer durability and A perfect finish, durability rises by about 15% compared to other brands, computer-aided lightening for extra weight reduction. High quality product, processed entirely on CNC machines. Lightened and anodised, for a longer life. Extract for mud, for better yield on muddy and sandy soils.33,00 € VAT included
These crowns are machined from 7075 T6 CNC for greater smoothness, surface hardening treatment of 50 microns for a longer duration, of the toothing profile studied for the last 20% more than the best competition and reduce the power consumption.28,49 € 34,75 € VAT included
Brand new crowns Moose Racing DUAL SPROCKET aluminum with the outer ring of high strength steel. Easy to see the advantages:
-Lightness (a totally steel crown weighs 3 times more, unbalancing the weight of the bike, especially on jumps).
-Resistance, in fact, the point of contact between the chain and the crown is made of high strength steel which allows to extend the life of the crown-chain and sprocket.
Available in different colors depending on the model.
The evolution of the exclusive Crown Sunstar Works-Z, now made of high quality stainless steel. It weighs up to 50% less than standard steel crowns. Heat treated to 100% and even lighter than before, with new lighteners to further reduce the weight, has a greater hardness 5 times of an aluminum crown and 2 times that of a standard steel crown. Up to 4 times more resistant with 1.2 times the lateral force of any aluminum crown. Great self-cleaning capacity, thanks to the offset tooth design, the Z-Works crown extends the life of the entire chain drive system. The lightest steel crown on the market.71,39 € VAT included
