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.
Chain link openings vary, too. We offer chain with elongated link size called Long link. This is a practical choice where connections must fit mid chain, not the end link. With the longer links, shackles bolts fit anywhere along it's length, whereas standard coil sizes may only fit shackles on end links. Long link also makes the chain lighter than equivalent length of standard chain. BBB is a compact link style often of standard commercial quality chain such as Grade 30 or 43.
