  • Great alternative to 11 speed upgrade

    I've been running 1x8 drive for several years and loved the simplicity, but wanted lower gearing for true mountain bike trips without having to put my granny gear back on. Also, I noticed I was really only using about 4 gears on my local trails. I matched this cassette up with a 26t NW front ring from Neutrino and a Wolf Tooth Road Link (adapter to let your derailleur shift into that 40t sprocket) both bought off e-bay.

  • A good cheap way to go.

    Bought this to replace Shimano 11-32 while converting to 1x8 drive. This gives me almost the granny gear I had but with a simpler and cleaner drivetrain. Used with a 32 front, this makes my old legs happy. I did add a goat link to get my Acera to reach the 40. So far no chain drops, but I have a bash ring. Hope this info helps.

  • Just what I needed

    Turn your bike into a climbing machine. Pair with a derailer extension and new chain to make a huge difference in your climbing abilities !!
