The box three prime 9 was the best drivetrain I could get for my needs, you get all the range for a full pro drivetrain with only 9 gears and it's very simple. Install was very quick and everything worked perfectly out of the box, I even got upgraded to a box one chain for free, much appreciated. Switching to 1x9 was the best I could have done, front derrailleur is gone, cockpit is cleaner, shifts are very crisp and I have the benefit of a LSD clutch so chain rattle is diminished a lot. Would recommend

Accidentally ordered the wrong size cassette when buying a Box 3 prime 9 complete set (late night purchase, not totally with it, my mistake). Talked to customer service as soon as they opened up the next morning and they were able to fix the problem even though when I called they literally sent my order to the shop floor 2 minutes before I reached their customer service rep. Customer service was very nice about it and I had no problems, they just took care of it and 30 minutes latter I had a confirmation email with my new order with the correct size cassette. And it arrived 1 day early so that was awesome.

Good experience. Quick to ship. Everything went well.

Perfekt! Thx

So far so good. I have not installed them yet but looking forward to it.

The shipping estimate was accurate and the installation process wasn't too difficult just had to replace my shifter cable. Good product seems sturdy as well.

Great products and direct shipping.

Great stuff but fedex played soccer with my package not cool.
