This is one of the new generation cassettes of beloved 12speed 11-52 t cassette. We successfully created the most competitive 12 speed 11-52 t cassette on the market and proved our quality. However, the weight is what we sacrifice, now we decide to make a difference. Our team working day and night to develop some mind-blowing product. And of course, we still have the best cost-performances, without any sacrifice. The Earlier Thoughts. Talking about lose cassette\'s weight, the first thing we came up with somthing like this. A CNC machined spider and some steel cogs riveting on it. This is might be a cheaper solution, but larger cogs would still be quiet heavy. The weight could go up to 415 grams, even that is better than orginal 660 grams, but we are not satisfied. The Idea Of CNC Larger Cogs. After studing a lot of famous brands, we are start to looking into a one-piece full CNC solution. Full steel design is the best solution for the strength and durability, but full steel cost a lot. Then we consider the full aluminum design, but use aluminum alloy to make smaller cogs could make cassette easy to wear out. So we decide to only use aluminum alloy to make larger cogs. Smoother Gear Ratio We use11-13-15-18-21-24-28-32-36-40-46-52Tgear ratio,With a smoother gear ratio, it will be easier for rear derailleurs to shift. Full CNC Machined 7075 Aluminum Lockring Not only beautiful anodized color,these lockrings could be extra lightweight and strong. REAR DERAILLEUR HANGER EXTENSION ALSO COULD IMPROVE THE SHIFTING PERFORMANCE OF LARGER CASSETTES
