Cleaning a vintage CCM bicycle wheel


The Canada Cycle & Motor Company (CCM) has a fascinating history. For many middle-aged Canadians today, during their childhood CCM was a respected household name for hockey equipment, including ice skates, pads, and sticks. But the company's origins date to 1899, when CCM manufactured high quality bicycles in Toronto as part of its operations with the Russell Motor Car Company. The picture below is from CCM's 1918 catalogue.


CCM's bicycle products carried through to the company's demise in 1983, although by the end they had gained a reputation as a cheap department store bike that competed with increasing low-cost imports from other markets, such as Asia. 


Although the lustre of CCM bikes has long since waned, many years ago I considered myself fortunate to have found a rear wheel from a CCM bicycle in a now-defunct antique store in Carleton Place. It's been on my to-do list for years to clean up this wheel so I could give I could display it in my office. 

According to information from this interesting site (based in nearby Perth, Ontario), it appears my wheel could date to 1908-1918. The hub is a "Hercules" armless coaster brake, one of CCM's models manufactured under license from Musselman (patent number 106391). 



The oil port in the middle of the hub is inscribed with what appears to be "JOSLUCASL2", "No 1" and "BIRMM". (I'm guessing this is a part made by Lucas Industries in Birmingham, England, which was a major centre of bicycle and motorcycle manufacturing and home of BSA.) Apparently, CCM marketed oil specifically for their Hercules coaster brake hubs in the late 1920s. Their brake grease didn't appear until the 1930s and even then the company recommended the periodic addition of a few drops of oil to preserve performance. (As a footnote, there was debate among cyclists as early as the late 1890s as to whether grease or oil was better for hubs!)


Since it's not a "New Hercules" model, it's almost certainly the original 1908 model as shown in the patent and product sheets below. 



The wooden rim was painted black and appears to lack evidence of pin striping, which was added to later, fancier models. It also lacks a metal rim strip added to reinforce later wheels, although there are two small nails and some cloth remnants near the valve hole, which probably held a cotton rim strip. As with modern rims, the valve hole is opposite the rim seam, which in this case is a glued finger joint. The wood is fine-grained and appears to be hard maple or maybe birch.



The hub and spokes are nickel-plated, the nipples are brass. 


I disassembled and cleaned the bearings and coaster brake mechanism, and straightened and chased the threads on the axle. It now works smoothly when reassembled! I also removed surface rust from the spokes and applied a conservator's microcrystalline wax to all metal parts to retard further corrosion. Varsol and linseed oil were used to clean and protect the wooden rim, as I felt this was an authentic and appropriate treatment given the probable age of the wheel. Unfortunately, there's too much corrosion to risk tightening the fragile spokes, so it won't be possible to true up the wheel. However, it holds its shape well enough as-is. 

As a bicycle enthusiast, I'm thrilled to have this wheel on display as a reminder of Canadian cycling heritage. I wonder who, a hundred years from now, may admire some of the wheels I've built?
