11 Speed Wide Ratio Super-Lightweight SLR Cassette 11-50 t by ZTTO
We never stop innovating! We created the most competitive 11 speed 11-50 t cassette on Amazon.com and proved our quality. However, the weight is what we sacrifice, now we decide to make a difference.
First, we came up with a cassette with aluminum spider design. Not only stronger, but also 80 grams lighter than our earlier design's 660 grams. 580 grams is not good enough, we keep searching a way to make cassette lighter.
After thousands time of trail and error, we finally came up with a new design and decreased the weight of 11 speed 11-50 t traditional cassette to astonishing 350 grams and we also find the way to control the price and the quality. We use CNC process to build our lager cogs and spider from one single piece of T651 heat treated hardened 7075 Aluminum. We know that using aluminum to make the small cogs could be a real waste of money because it takes a lot of effort to make the small cogs strong enough. We decide to go with steel cogs and aluminum spider solution. As a result, our latest extra light-weight 11 speed 11-50t SLR cassette is 310 grams lighter than our earlier design and also have a great cost performance.
