CCM Seville Road Bike

Do you know what year it was made? I'm wondering if it was made before or after the bankruptcy of CCM in 1983. Is a Shimano 600 set from the mid to late 1980s?

Why does it need to be restored? It looks in great original condition. Cables can be lubricated - just disconnect one end, hold the cable housing up in the air and pour or spray lubricant into it so it runs all the way down inside. When I've bought a bike like this that someone has spruced up for sale, my first question is "did you keep the original cables and tires?  As the saying goes in this hobby, "it's only original once."

...But maybe I don't understand what you are saying. Are you saying that the cables and shifters are not original and you want to find original, period correct parts for it?

This is a Weston manufactured model, circa 1979-1981. The serial number would confirm the build location and year. At the time, it was CCM's top model, though from an industry perspective it's not a high end bicycle. I'd place it at the crossover between entry level and mid-range. It's arguable as to which side of that fence is correct.

The Shimano 600 parts are 2nd generation Shimnao 600EX, which was  manufactured for the 1978-1983 model years. However, the bicycle does not use the full group as claimed. The derailleurs, shift levers and brakeset are 600EX. The hubset may be 600EX but I'd need better pictures for proper identification. The crankset appears to be the lower Tourney model, while neither the headset nor cogs are 600EX.

While the saddle has been replaced, a Vetta would not be correct. The Vetta brand did not exist until 1982. The original spec saddle was a Kashimax, though I don't know the model designation. From what I can see, all the other components appear to be OEM, though it is missing the brake hoods. Some may question whether one wheel is a replacement, as it would be atypical to have a large flange front hub paired with a small flange hub on the rear. However, it is correct and simply another example of the strange decisions that the company made during their final decade. 

Great comments, questions and feedback from Brian R and T-Mar. As far as I can tell all cables and shifters are original but from a quick go over they could benefit from replacement (maybe try and use the housing with Brian's suggestion to use some spray lubricant). T-Mar has probably provided a more thorough explanation as to dating of this model and the components used ... may well be another example of the questionable decisions made during the final decade by the company.

I will post a follow up message with better pictures of the components shortly.

Thanks again.

The cables are almost certainly OEM, given the amount of corrosion on the inner cables and the fact that red housing was factory specification on this model. Replacing the cable is a question of aesthetics and cost.

First, how much does the corrosion of the cable bother you? The inner cables are most likely galvanized steel wire, which was a popular, less expensive alternative to stainless steel cables. While it does corrode, it's actually a sacrifical coating that protects the underlying steel. Consequently, cable failure shouldn't be a concern, provide all the strands are intact.  If you can live with the looks, I'd have no qualms leaving it as is. Of course, if you're planning to sell the bicycle, it may be an issue with the potential buyer. 

Regarding the housing, the replacement will almost certainly be better than the existing housing. These days, most housing contains a Teflon inner liner that reduces friction, allowing better modulation of the brakes and slightly reduced lever force. Still, it's extra cost and labour over dribbling some lubricant inside the existing housing. It's arguable as to whether or not the perforamnce upgrade is warranted on a bicycle of this level.
