Box components Box Two Alloy External ENG Bottom Bracket 68/73mm Shimano HTII 24mm

Box Two external bottom brackets are a great choice for bike enthusiasts. They feature cold-forged and CNC-machined alloy cups, dual-labyrinth bearing covers, and precision sealed bearings. These bottom brackets are the perfect match for Box Three and Four cranks and offer an ultimate upgrade over the budget bottom brackets that come with most cranksets. Technical specs include a width of 68/73mm, an ENG BB interface, a Shimano HTII 24mm spindle type, 6061-T6 cup material, and a weight of 105g.

Using this Box Two bottom bracket is easy. First, make sure your bike's frame is compatible with the 68/73mm width and ENG interface. Then, carefully install the bottom bracket cups into the frame. Next, insert the spindle. It's important to handle the precision sealed bearings gently during installation to avoid damage. When it comes to maintenance, keep the bottom bracket clean. Regularly wipe it down after rides, especially if you've been in muddy or wet conditions. Check the bearings periodically for any signs of wear or play. If you notice any issues, it might be time to replace the bearings or the whole bottom bracket. Store the bottom bracket in a dry place when not in use to prevent rust and corrosion.
