CBC bicycles Adelaide. Early 70s "Custom Built 10".

Postby uart » Sat Sep 08, 2018 3:39 pm

Does anyone know anything about "Custom Built Cycles" (CBC) of Adelaide?

This one is believed to be from the early 70's (bought second hand in about 1976). It belongs to a friend, and I'm just about to give it a basic restore to get it functional. (The wheels in the photos are just stunt doubles while I test what tyres sizes will fit. The actual wheels are not in great condition and need a bit of work).

The frame (tubing) doesn't seem to be anything special. TBH it doesn't look dissimilar to entry level Apollos of the era. The components however (Durace and 600ex would have been pretty decent in their day.

I have seen a few others in my Gumtree/eBay travels, and from memory were the sort of thing that got stocked in sports stores like the Sportsworld and GX-Sports sort of thing. A small step up from K-Mart, but not much. Also from memory these were mainly re-decaled low-end Japanese trade frames with components one step up from entry-level. Have seen a couple with SunTour and centre-pulls.

Nothing special
Mmm, SunTour

Yep that would make a lot of sense..

Oddly enough I just picked up a Leisure Cycles Aus frame in Tange 900 which has been de-stickered, probably a Ricardo....trying to decide what to do with it.

Thanks CS, that was an interesting read. So this probably is an Aussie made frame from the early 70s, made in an Adelaide factory that was later taken over by Riccardo. Also very interesting to learn how Repco eventually bought them out for the *sole* reason of shutting down the last Australian bicycle manufacturer - just so they could get tariffs dropped on their imports. That was pretty underhanded. :(

Yes this frame is nothing special, with fairly modest looking tubing (don't know what it is, but definitely not Ishiwata or Reynolds or Columbus or the like). However this is a well made frame with fairly nice lug work, and has survived roughly 50 years in reasonably good condition.

I think that you may be over estimating the quality of K-Mart bikes of that era. As someone who owned a k-mart 10 speed "Roadmaster" in the very late 70s - early 80s, I can tell you for certain that even the most entry level of the decent brand bikes like Apollo were head and shoulder above those old k-mart things. I stopped using my Roadmaster in the early 80s and within about 5 years it had basically turned itself back into iron ore under the house. The tubing was really just "landfill grade".

I've got an old 1979 Kuwahara (Japanese) "Apollo I" frame here that I might eventually get around to building up, and as modest and lowly as it is, I still couldn't even compare my old Roadmaster piece of garbage to it.

Agreed, but these were the sort of bike you might find in the 1970s Indie equivalent of today's Rebel stores, and maybe comparing to Apollo/Shogun/Repco is probably a bit unfair to the gaspipe CBC..

The bike as it stands, roughly 56 cm square (C-C), is about 10.7 to 10.8 kg. This includes everything shown except for tyres, tubes, racks and mud guards, which are currently removed. I'm guessing it would come up to around 12 kg ready ride.

I gthink that's in line with the "nothing too special but also nothing too nasty" theory.

Seat tube diameter is bang on 25.0 which is interesting. The only other bike I currently have with that diameter is an old Peugeot Mont Blanc with their "Mangalloy" tubing.

Update.

I've just got this thing fully pulled down, and as expected the frame is far from anything special.

Comes in about 3.8 kg for the bare frame and forks - Id guess "hi-ten" at best.
