1985 Rocky Mountain Discovery sizing?

[cbappley]

I am the lucky new rider of a 20“ CToC seattube ,22 1/4“ CtoC toptube
vintage RMB. The 87 catalog states 20 1/2“CtoC? as the largest frame .yet the picture of the model looks gigantic (23“)at least.
serial is A6A00264? any info on the decoding of that # also appreciated.
i am lucky to catch it from RetroRoy who referred me here.
stoked,

HI and welcome.

Best way ive found to measure RM's is with a tape, regardless of what the catalogue says, they often vary slightly.

Have feel free to post pictures of you bike
