7 Speed Chains (for internally geared hubs)

Which chain should I get for my bike with an internally geared hub? These chains are designed for use with internally geared hubs with a single 1/2 x 3/32 sprocket. They are very strong (particularly the 7E8 and 7R8), but they're not flexible like a derailleur chain. For 6, 7, and 8-speed derailleur bikes, use Connex 8-speed chains. Connex 7E8 Best for eBikes Nickel plated. Reinforced inner and outer plates transfer the added torque produced by the eBikes. 7E8 will NOT WORK with derailleur-equipped bicycles. Spring Clip connector included. Connex 7R8 Best for heavy-duty work and touring bikes The reinforced chain and inserted bushes provide an extremely long service life. Suitable for internal hub gear systems and single-speed bikes. 7R8 will NOT WORK with derailleur-equipped bicycles. Spring Clip connector included.
