ZTTO MTB 11Speed SLR Cassette  11-50T

ZTTO never stop innovating! This is one of the new generation cassettes of beloved 11 speed 11-50 t cassette. We successfully created the most competitive 11 speed 11-50 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 Balance Between Weight and Cost-Performances

After thousands time of trial and error, we finally came up with a new design and successfully decreased the weight of 11 speed 11-50 HG splined freehub type cassette to astonishing 350 grams and we also find a right way to control the price and the quality. Now, you can save nearly 300 grams of weight without emptying your pocket. 

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 580 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

Instead of traditional 11-13-15-18-21-24-28-32-36-42-50 gear ratio, now we changed to  11-13-15-18-21-24-28-32-38-44-50. With a smoother gear ratio, it will be easier for rear derailleurs to shift.
