As you may have noticed, I´m a finnish guy living in Finland and I was wondering (because I´ve never seen them here) what is the idea of skip tooth spocket and chain? Is it somehow better than regular combo (can´t think of any reason why)?
Skip tooth......what´s the idea?

"Block chain was very simple and easy to manufacture. A metal block with two holes onto which side plates were riveted creating a link. The spacing of this chain was 1 inch pitch. However block chain tended to wear out rather quickly. Along comes a better idea, Roller chain constructed of hardened rollers sandwiched between metal plates and riveted together. It was more durable and less noisy than block chain. The 1 inch pitch standard had already been established by block chain. 1 inch pitch roller chain (what you are calling Skip tooth) is the same spacing as earlier block chain. later in the 1910's a few bicycles started to adopt a different standard 1/2 inch pitch. 1/2 inch pitch chain ran quieter than both block chain and 1 inch pitch roller chain. Both standards 1/2 inch pitch and 1 inch pitch continued side by side until the 1950's were 1 inch pitch started to be phased out. Both 1 inch pitch and 1/2 inch pitch roller chains were durable however 1/2 inch pitch chain is quieter and works better for derailleur systems. 1 inch pitch chain was simply a carryover from the block chain 1 inch pitch standard established and used primarily in the 1890's."

A general consensus puts the last skip tooth bikes sold in 1955, by Murray. Most likely using up old stock. Of course, there were newer road bike cogs with similar looking skipped teeth, but it's still the 1/2" pattern. -Adam
It is my understanding that along with the above explanation, that it all came over from farm machinery, which was inch pitch, and they used chain that was currently in production at that time. Cheaper that making their own...
