Pete, Harvey, All: The common terms for the 1-3/16 bicycle chains more depended on where you lived, and how old your mentor was. Skip tooth, as many people thought the sprocket looked like it had every other tooth knocked out. Other terms: skip link, inch pitch, double link chain, then of course either roller or block chain. Some riders referred to the block chain as a racing chain. The weight difference was always a factor, but the main difference was the feel of the ride. When you feel the block chain click over the sprockets and register that solid drive in your legs, you know it's fast. Roller chains are smoother and quieter, but just don't have the snap. Riding a block chain is one of those subtleties that have to be felt, It's an experience that you won't forget. Like the whirr of the peloton coasting and it sounds like a swarm of bees. Riders liked the smoothness and gave up the response and snap for the ability to git closer gear ratios and the convenience of changing ratios without moving the wheel too much, and it was a fairly quick conversion between about '54 and '59.
