If you ride wet conditions however, it might actually help to keep the water and grime out... Don't take my word for it though.

I prefer a higher spec chain for several reasons. They don't rust overnight when I put the bike away wet. I don't have to be constantly measuring the chain for wear. I don't have to be "meticulous with chain cleanliness and lubrication", although I do look after the transmission. I don't have to worry about where I ride. I measured the dimensions of the chain with a digital gauge. Externally it was the exactly same across the outside of the plates. Internally there is a difference of 0.3mm between the plates when comparing the two. Chain reaction Cycles and CRC are trading names of Wiggle Ltd (In Administration) registered in the United Kingdom at 1000 Lakeside, Suite 310, Third Floor N E Wing, Portsmouth, Hampshire, PO6 3EN,We have a loyal customer base that's been waiting for this," said Christian Hamann, managing director of Wippermann, which owns Connex. "All of our chains offer a very good wear characteristics. The Connex Link is unique and adds value." Well I have jumped down the rabbit hole on this one. I have a couple Trek Rails (ones mine, the other is shared between my wife and my oldest kids). The KMC X-Series has been designed with the specific characteristics of the Shimano, SRAM and Campagnolo systems in mind and will meet the most demanding requirements. Elaborately designed and manufactured, the X-Bridge technology, thanks to precisely chamfered plates, allows smooth propulsion and perfect gear changes in all driving situations.

For an eBike, I think you're best off leaving the chain clean and un-lubed year-round. Even with stronger eBike chains, you'll be wearing them out faster than they can rust in wet conditions. Lube just makes the drivetrain harder to clean, and more likely to wear faster. If you wish to return your bike to us please keep it in the box it arrived in and call us on 01772 644340 and we will arrange a collection.

There is a lot of knowledge on this forum about different ways to get best value. One is to boil the chain in wax. Another is to use three chains in rotation - swapping every few hundred miles or at a specific wear %. That way the gears will never reject a brand-new chain. There are other methods. At Eurobike this week, both companies unveiled plans to enter the 12-speed market in January 2020. Connex's 12SO and KMC's X12 and e12 chains are compatible with Sram 12-speed mountain bike and Shimano 12-speed drivetrains.

Our special e-bike version is more durable because of the enhanced riveting," said Harrie Hofstede, KMC OEM sales manager. "Both versions are an upgrade on durability." I now have 3 new deore chains which I removed the factory grease. Two of which I have prepped using Speed Wax, which is the full on melt in a pot wax. They will both be used on on my bike. The melt wax is a bit of a pain in the ass, so I will run one speed wax chain and swap it out every 100km or so depending on conditions with the second speed wax chain. I can then refresh the first chain in my spare time. Offering high performance and maximum durability, the KMC E12 EPT chain is a perfect choice for 12-speed derailleurs. Including faster and smoother shifts and longer chain life.

The KMC is chamfered on both sides/symmetrical, Shimano only chamfered on the outside plates/asymmetrical and must be fitted in a certain way.
