Not at all odd, in fact it's par for the course and for good reason. CCM was basically non-competitive on the lightweight market, with the exception of the bottom of the line Targa. The Targa sold primarily to those people wanting the lowest price 10 speed with a recognizable brand name and/or adults buying bicycles for their teenagers. These adults had grown up on CCM, when the brand was still revered and they still considered CCM a quality bicycle.

But by the boom, CCM was in trouble due to various reasons and this was reflected in erratic quality. This was noticed by most consumers, who were typically males, late teens or early twenties and in control of there own finances. They were swayed by the allure of the exotic European and Japanese imports. Models like the CCM Concorde could just not compete with a Raliegh Grand Prix or Peugeot UO8 and in the latter years of the boom, the Sekine SHB/SHC. The Sekine sold in droves and with good reason. It was Japanese design and quality, made in Canada, with good looks, performance and reliability.

So if you're looking for Canadian, boom era lightweights, the most likely find is a Sekine SHB/SHC, followed by a CCM Targa. You'll also find quite a few CCM Elan and Elite, but they are city bicycles whose appeal is readily explained by the more adult oriented market who still revered the CCM brand.
