Retro Newbie
ok.. for what it's worth there seems little info here on Sirius bikes..i've just completely upgraded mine initially bought in 1997 as a 'fast audax' bike from Kingswinford, rather than Dudley . Kept hold of the paperwork extolling the virtue of 631 and 853 so include it for reference...It's come up rather nice, though the kit is not at all retro . So glad i never sold it...been languishing in the shed for about 12 years !
