CHAIN FOR 6 7 8 SPEED AND ROAD BIKE The missing link makes the chain easier to install. Titanium nitride coating makes it free from rust to provide durability. The 116 links can be adjusted to the tension of your choice. Please be careful not to overstrain. Length: 116 links | 1/2 x 3/32 The chain elongation prevention structure reduces the frictional force to the cassette and gear. Even in the upper slope where the load is high, the chain wont ride on gears, and it can make a sure and quick gear change at that time. Weightabout 314g Usage: 6/7/8 speed Color: Black Silver In-box package Cautions: our chain may OEM from YBN/KMC/SUMC, so different batches may look different, if you mind it please dont buy it Precautions for installation Please attach 8-speed dedicated chain in case of shift defect. As it is a consumable item, please replace it periodically. With the feature of easy installing and assembling, please use chain cutter, gloves and grease when you replacing. Chain cutting is necessary for length adjustment when you install at the first time. Please align the gear position before cutting ,and check the angle of the derailleur at that time. It is better to fix with a holding wire in case of flying when cutting. Precautions for cleaning Please maintain regularly so as not to impair the performance. Keep the surface of the chain dry by wiping the chain with cloth and towel after run. With normal washing, oil lubricating with oil and wiping off dirt and old oil is sufficient. Please do not use dry parts cleaners . (If dirt is hard to wipe, you can repeat it. It is fine with chain oil that you use regularly.) Please refrain from acts such as immersion in the liquid of parts cleaner.
