With the new Cassette sunrace of 1x10 11-40 or 11-42 teeth you have the solution, this could be the answer in most current Shimano and SRAM10 speed systems, simply replacing the current 10-speed cassette with this large one.
Description:
Made of Aluminum for bushings with standard core. 448gr.
Have you been circling the 1x10 or 1x11 for a while, but do you find it too expensive?
This cassette has an excellent price and a more efficient configuration than 40- or 42-tooth loose sprockets.
This is a smooth, seamless block of teeth, designed for smooth and smooth operation.
Works with most medium or long box rear changes.
In some configurations, the change screw that regulates the distance will have to be replaced by a longer screw.
