Just to complete the KMC set I thought I'd just document for posterity the recommended and best chain to use on a VeloTron cycling Ergometer. The KMC Z610HX is inexpensive and is a 1/2"x3/32" single speed chain with a pin length of 8.0mm and 112 links. The chain does not have to be shortened to fit the VeloTron when the standard chainring/sprocket sizes are in use. The best things are that they are not at all expensive, work superbly, and include a MissingLink. Perfect.
