Yes, I thinks it’s something like that, a Saracen or a Sintesi. Sadly, none of them sold a frame like this. I’ve taken of the rear triangle and found that it has enduro bearings. Now, that doesn’t mean anything, but if it was on there when the manufacturer put it on, that means it was mainly meant for that type of sport. The closest I’ve found was a specialized enduro bike which was practically the same shape, just didn’t have the multiple mounting holes. I’ve checked Halfords history, there are no bikes that look like it, who ever had it must have taken of the logos (or it never had logos depending how bad it is) so that must mean they were stickers. It is a sort of cherry red underneath and there is a very unusual feature on it, instead of being mounted on the top of the bike frame, the manufacturer has mounted both bike bottle cage mounts on the underside of the down
Tube. It is believed that when a bike is stolen, that the thief, takes of all the good bits, paints the frame and leaves it somewhere on the road or something.(because of the serial number)
