Box Three P9 X-Wide Single Shift E-Bike Groupset

Box Three P9 E-bike groupset

Really pleased with this purchase. Haven't installed on my 2018 Turbo Levo but looking forward to getting this on there this weekend. Quality is great and the price was exceptional. Highly recommend as an alternative to the big two :-)

The components were easy to install and it works much better than the eight speed it replaced. Wear over the 600 miles it has been on the bike is minimal. It has required very little attention to keep shifting beautifully. Shifts are smooth, fast, quiet, and predictable. The only problem I had was getting the cable tension right, but that is something I always struggle with.

Want this to work so bad

As the previous review mentioned, sometimes when you want something to work so bad you see it through rose colored glass. Shifting - while its not as rough on my thumb as the previous review mentioned it is difficult. There is a webinar on the box 3 and you can see the difficulty the Product manager has with not pressing hard enough to shift as well as the extreme amounts of play. Chain tension. The clutch leaves much to be desired. Sending you bike off anything greater then 6 inches will cause the derailleur to shift. Chain slap is now a thing again :-( The main reason I bought this was due to only getting about 400 miles off my slx chain and cassette. Really hope I get at least 1000 out of this group set.
