Good value basic bottom bracket but poor instructions
"This bottom bracket was reasonably easy to install with a Park Tool BBT-69 on a torque wrench. It was factory greased inside and out. Despite the warning printed on the parts to not disassemble, this bottom bracket is actually three pieces: one right cup, one left cup, and a plastic spacer tube in the middle. You will need to pull the pieces apart to install. Leave the tube inserted into one of the cups, it doesn't matter which one. The cups are printed with an R and an L indicating which side they are installed on. Package includes 4 spacers, 3 are 2. 5mm thick. For 73mm wide bottom bracket shells you will use one 2. 5mm spacer on the drive side. For 68mm wide shells you will use two 2. 5mm spacers on the drive side and one 2. 5mm spacer on the left side. There's another very thin spacer included, but it's not clear what purpose it serves."
