Box Four 8-Speed 12-42T E-Bike Cassette
SKUBX-CS4-08A1242-BK
The Box Four E-Bike Cassette offers high gears with more teeth to withstand the rigors of modern E-Bike riding. Adding an extra tooth to each of the three highest gears provides increased durability and decreased wear by distributing the load over a larger area! Box Four adapts our Prime 9 philosophy of durability, simplicity, and reliability at a great price point. All cogs are stamped from steel, given our durable black coating and then the larger cogs are pinned to each other with spacers for easy installation.

I have no complaints I must wear shift h gears than 12 I'm an old single speeder I hate shifting everything so far is awesome it shifts as good as my $400 GX eagle SRAM electronic that's what I took off
United StatesGreat upgrade for my ebike conversion!
I converted my old Cannondale to an ebike using a TSDZ2. On the first ride using the original Shimano XT 9-speed, I dropped the chain on a bumpy downhill section. I upgraded to the 8-speed with the chainring and haven't lost a chain since. The extra range on the low-end is really nice and the 32Tx46T gear allows me to climb almost anything. Its very robust and I can shift under power even with the motor putting out about 750W. The value is excellent and compared to other extremely expensive drivetrains, I can affordably replace components if they wear out from the added load of the motor.
