• Bob Griffin was a frame builder who up until about '94 ran a shop in Hungerford Street Cheltenham.
    He built frames for over thirty years and then went to work for Roylans after his shop closed - he no longer builds frames but I think he's still at Roylans
    IIRC all his work was custom, usually Reynolds 531c lugged frames.
    I knew him back in my Cotswold league racing days.

    edscoble did a Griffin CP, and there are plenty other resources on the web: e.g. this one in which Bob himself makes an apprearance and an offer of assistance...

    Out of general interest, Here's an ad for his shop from the comic in '91.
