Wide Range Drivetrain: 9-Speed 11-50T Cassette 

A wide range drivetrain refers to a big cassette with gear ranges that is capable to get you up on steep hills and down on the road.
The 9 speed cassette features cogs from 11 teeth to 50 teeth.
Divide the number of teeth on the largest cog by the smallest, then multiply that by 100, that gives this 11-50t cassette a gear range of 454%.
9-Speed 11-50t Cassette (50T, 42T, 36T, 30T, 24T, 20T, 16T, 13T, 11T)
Anything around or over 450% can be considered wide range.
Paired with the SRAM X7 shifter and SRAM SX-4 derailleur with 1:1 actuation ratio.
The SRAM SX-4 measures 95mm long and it has been proven to give good clearance in fitting a 11-46t cassette with hanger extension.

This is going to make a much wider gear range compared with the old 11-28t cassette.
The hub is a 10-speed hub, therefore, no spacer is required to fit the 9-speed cassette.
A hanger extension is required to fit with the wide range cassette.
Tighten the B-Tension screw to extend the gap between the guide pulley and the bottom of the cog.
Adjust the limit screws if necessary.
Let’s take a look at the gear ratios with the 30t chainring and 11-50t cassette.
Gear ratios ranging from low 0.60 to high 2.73.
