Summarized by Shop
Our Box Three tier delivers many of the same capabilities of its more famous siblings yet it's built upon a simpler platform. Cassettes are accessible at 11-46T or 11-50T and fashioned with steel spiders. The derailleur exploits our Limited Slip clutch technology without the Tri-pack features. Shift easily with a comparable mechanism, alt

Good profuct
Great drivetrain overall but it did have some trouble getting trough all the gears after a few days of use. And then I went to the bike park and it completely stopped working but I don’t know if that is just normal usage problems or something to do with the fact that the mechanic that helped me fix the flat wasn’t the most carful so yeah great product overall and I would buy it again. And if there was a warranty I could buy that would be nice but maybe I just missed that

Good for the sale price. I'd buy Deore/cues otherwise
Works well. I would like a couple more gears. Shifting can be a little funky in the middle of the cassete. Solid little groupset.
