Box Prime 9 group opinions


Any mtbers been trying box prime9 and have opinons about it? Been thinking about using it on my big bike!

I use their 11 speed. It sounds like a bear trap when it shifts, but feels crisp and smooth.

No personal experience, but my riding buddy got one when he couldn’t find a replacement. He enjoyed it for about six months but said it was clunky and felt some drag. He switch back to deore recently.
