AGE / VALUE:   How to tell the age of a bike posted by: Adrienne on 8/9/2006 at 7:10:01 PM
Does anyone know hoe to tell what year a Ross bike was produced in. There is an alphanumeric code on the base of the handle bars that says A3345-77. Does this mean the bike was made in 1977? I appreciate any help at all on this!

Thanks!

Hi Adrienne,

Often the best hints come from the components, which often have date codes. Certain characteristics of road bikes have evolved over the years, with 6-speed freewheels becoming popular in the late 1970s, followed by 7-speed, then 8-speed, etc. Centerpull brakes and high-flange hubs were popular on high-end bikes of the 1960s into the early 1970s, when sidepull brakes and low-flange hubs became ubiquitous.

As for Ross framesets, unfortunately I am completely ignorant of their date coding system. (Now I'll have to check the date code on my ca. 1990 Ross mountain bike. :) )

I would be very surprised if it were anything other than English/ISO-threaded with a 68mm wide BB shell. Spindle length would depend on double versus triple chainring and on the crankset used.

AGE / VALUE:   Japanese Rod Brake Bike posted by: joel on 8/8/2006 at 1:48:18 PM
No response from the English crowd. Maybe you guys can help. Can anyone tell me more about this bike? I believe it is Japanese-made and most likely pre WWII. There are many brass name badges with the name TKR on the steer tube, fenders, chainguard, ect. On the sprung leather saddle there is a TKR logo and the words Tanaka Seisakusho below. I'm guessing this is the same Takara company that made bicycles in the 70s/80s ?? It is a lady's single speed roadster with rod brakes, caliper type (ones that lift up to the rim) in front and a drum brake in back. The rims are very heavy with rolled edges similar to ones I have seen on early English bikes, Schwinn s4 tires fit them. On the enclosed chainguard it says THE TNK CYCLE, trade mark, NEW SUPER. Lots of Japanese writing on the name badges. THere's a cool deco looking aluminum fender ornament, also embossed TNK. On the seat tube are the numbers 33 2 22. I wonder if this could be the date of manufacture??

I'd be surprised if you had a Japanese bike that old. My guess would be fifties. Japan is full of bikes like the one you describe. If it sez "Tanaka" it's not a "Takara."

Sorry, I typed the wrong name. It is Tanaka, NOT takara. It would seem unlikely that a Japanese bicycle would have been imported to the US so soon after WWII (1950s). Since it has english writing on it, I would assume it was for market either here or in Europe or Canada. It is certainly possible that it was made in the 60s or later, but the construction and design seem much older. Just thought someone might have seen one of these before...

Sheesh, lots of typos. Sorry. That should be TNK not TKR. and Tanaka, NOT Takara...

I'd say probably '60s or '70s. Remember, the Japanese began large-scale production with used English tooling after WWII.

I recently had a 1936 RRA shipped to me via FedEx. The rarest of rare alloy railed Brooks B16 that was supposed to be in the box was either lost in shipping or stolen out of the bike box. Shipped from Rochester NY. So if anyone comes across my missing saddle I'll gladly give some reward. Thanks
