A bottom bracket’s job can be quite thankless when everything is working but it can also be a huge source of trouble when using inferior products. The biggest issues we have run into include inferior bearings and poor fit. The stock bottom bracket used on your bike is typically the cheapest option available. As a result, the bottom bracket will feel gritty and require more force to spin. Another issue we commonly see is poor fit within a stock bottom bracket. Most OEM bottom brackets/adapters are plastic which will cause creaking issues over time.
In the past, ceramic bottom brackets started at $300+! We recently teamed up with Kogel Bearings who offers a ceramic bottom bracket from $159 to $199. Their bearings are infinitely smoother and offer a housing made from aluminum. Stop by the store and turn the cranks to feel the difference for yourself!! There is no doubt you’ll get some extra wattage with the same amount of effort.
