Is it really necessary to spend upwards of $20 on a chain lube specifically designed for recumbent bikes, or are the manufacturers just taking advantage of the niche market and overcharging for what is essentially the same product as a standard chain lube. Ive seen some reviews that claim certain lubes are recumbent-specific due to their unique properties, but when you break down the ingredients, theyre almost identical to standard chain lubes. Whats the real difference here, and are recumbent riders just being taken for a ride. Are there any actual, tangible benefits to using a recumbent-specific chain lube, or is it just a marketing gimmick.
