Buying a chain is usually one of the last things thought about when building up a new bike, but as the saying goes “last but not least”. The chain among other parts of the drive train is what separates BMX from scootering and therefore is an important part of the bike. Before choosing your next chain read through some things you may not have considered or thought about before.
Chains come in two different types, Half Link and Full link, half-link chains offer smaller (half) links that are joined. Similar to the pattern of a fish scale half-link chains have less steel per link and therefor offer a stronger design because the pressure is spread across more links. Full link chains are the classic style of chain, tried and trued this style of the chain has been around for years and continues to be used. Several companies offer chains in both full and half link-style chains while some stick specifically to one type. As mentioned above Half link chains offer a stronger more durable design as stress is distributed across more links. Half link chains also offer a more adjustable rear end size since the chain can be cut closer to the drop out slamming the chain and shortening the back end. Half link chains offer a different look to your bike that can be taken either way and at the end of the day is a personal preference.
Depending on the type of BMX bike you ride you will most probably need one of the following sizes of chain for your bike. These sizes refer to the thickness of the sprocket where the chain meets the teeth of the sprocket. For the majority of BMX bikes, the chain will be a ⅛ inch size
Bmx Chains come in a variety of styles and strengths and so they also come in a range of costs starting from $20 to over a $100.
