Begging the indulgence of anyone knowing the specs of their mid-80's Tange 2 tubed Centurions. I am looking to follow a hunch that my bike may be re-badged Centurion model;
I've taken some of the vitals of my apparent '86 Canadian market Raleigh Criterium and was wondering if they bear any resemblance to any 85-86 Centurion models.
(bear in mind I'm not frame builder but having perused specs before, I'll try to use common conventions and tell you whats being measured and from where to where.)

Raleigh Criterium, SN N6A6798

Seat tube (centre of TT to centre of BB) - 62cm
Top tube (centre of ST to centre of HT) - 57cm
Head tube (total length) - 20.8cm
Head tube (centre of TT to centre of DT) - 16cm
Down tube (centre of HT to centre of BB) - 62cm
Chain stay (centre of BB to actual end before drop-out) - 38.5cm
Seat stay (total length of stay) - 54.5

Geometry is based on the assumption that TT would be parallel to the ground when bike is shod. ST angle & HT angle were measured against TT with a particularly crude protractor.

ST angle - 72 degrees
HT angle - 107 degrees (this, I'm figuring would translate to the more recognizable 73 degrees in relation the ground)

This is in no way life or death. I've already bought the bike in question and its being built up to join my stable. I'm just curious about its lineage.

Thanks,

Dave G.
