More Info:

1. Unlike the bottom bracket used in the videos, Box One (aka Vector) M35 bottom brackets come with only one dust cover on the non-drive side. Do not look for a missing dust cover, there is only one.

2. Installation requires two M35 BB cup tools, which are provided with the crankset. Following the instructions in the videos, use BOTH BB cup tools to hold/tighten BOTH cups when installing. Two 1/2″-drive ratchet wrenches are necessary to do this.

3. PF30 frames require the use of the Delrin sleeve, while the BB30 frames do not.
