Really great budget friendly option, if issues arise I will update.
This worked great. I put it on my entry level Fuji Nevada 1.9 and it has really changed how the bike performs especially going uphill. Shift can be a little stiff, but as long as its installed and adjusted right it seems to hit its mark every time. Instructional video for install could use some work, there are times the really bad background music overwhelms what is being said so you have to guess or find other peoples video. Good product for the money.

Shift on
At first had some install issues but technical support was great. Once tuned everything worked great. Shifts great and so far continues to. I appreciate the wider range of gears compared to my old cassette.

Installed easy, shifts better than group sets that cost twice as much.
Installation was easy, and it came with everything you need to install an entire new group set aside from tools. Shifting is rocksolid, and the gear ratios are perfect.
