YBN Yaban Chain 12-speed SLA1210-TIB | 126 links with chain lock Black YBN's 12-speed chain is one of the lightest on the market and comes with a precious golden Ti-nitride coating. For a low weight without affecting the strength of the bolts of the chain are hollow drilled. The long shelf life of the chain comes firstly through the Chromium Carbide Surface Hardened Treatment - a process which increases the hardness of the pins by a special surface treatment many times. Furthermore, the chain works with a SLA coating (Superior Lubricating Aid). YBN has spent 2 years developing this Ni-PTFE Teflon coating. The chain generates less friction, runs quieter and attracts less dirt due to the smooth surface. Of course, the tabs have special processing to ensure a clean and fast switching process.
