Our Mission: To protect, preserve and promote the natural integrity of Radnor Lake through land acquisition, environmental education and park support.
Chains up to 12 mm thick are generally portable: you can carry them around on your bike every day. The long ones will be really heavy though, so please check the weight. Above 12 mm the chains are more suitable as stationary locks: you would leave them wherever you lock your bike for long periods of time.
This means the perfect chain for your bike should have a larger width than the sprockets and chain rings. The majority of BMX bikes on the market come with a chain width of 1/8 inch, while derailleur chain bike chains measure widths of 3/32 inches.
