The Shimano CN-HG700 Chain has been developed to work with the 11-speed drive train that makes this most recent Ultegra groupset one of the best buys on the market. It has all the innovative advancements that makes the CN-HG900 chain so amazingly smooth, while gaining just a little more weight, which helps it shed loads of cost.
The CN-HG700 Chain uses a PTFE coating to keep the friction down ensuring a smooth interaction with the cogs and rings. PTFE, aka generic Teflon, is essentially another magical plastic that, when used as a coating or lubricant, reduced friction, wear and energy consumption. When used on something like a high-performance chain, it means that more of the power of your stroke is getting onto the ground while the durability of the chain is enhanced as well.
The CN-HG700 chain has also shaken off the directional, asymmetric design of the 6700 series chain. This means that you don’t have to worry about putting the chain on the wrong way. Being slightly narrower than the 6700 chain, Shimano was able to make use of the effective interaction between the chain and the shifting tooth profiles, making an asymmetric design unnecessary. The narrower chain allows for the gearing to be precisely tuned according to the gear ratio the rider needs. Having a narrower chain marginally reduces weight too.
The Shimano CN-HG700 Chain offers the sort of smooth shifting and silent operating that you may have thought was only possible with electric groupsets these days. Its durability and efficiency will give you one less excuse to shell out beaucoup bucks on one of its bigger brothers.
