The Wippermann 10S1 is a completely stainless steel chain - both inner plates and outer plates are produced of stainless steel for outstanding durability and reliability. Stainless construction is much more stretch resistant than ordinary steel and has far superior glide, offering a very smooth ride. Hollow pins help shave weight while chamfered outer links shift well and fit perfectly between the cassette cogs. Wippermann claims and we agree - this chain will lasts 20% longer than a standard chain. Brilliant Connex link makes the chain a snap to install or remove.
Wippermann's 10 speed chains have a 5.9mm pin length and 2.2mm roller width so they are compatible with all current ten-speed drivetrains including Shimano, Campagnolo, and SRAM.
This chain is not made completely of stainless steel. The pins were rusting by the end of the degreasing process. Looks like only the inner and outer plates are stainless steel. That doesn't make the chain worth the price for anyone who will see salt on the road during the winter.
Used this chain for years on Campy and is flawless.
