If you are based in Suffolk then Madgetts in Diss might not be too far away, they are a proper old school bike shop

Thanks for this, very much appreciated.
I had already emailed a local chap and asked if he had any experience of 'older bikes' and told him it was an older Orange. He came back with 'Absolutely' and explained he had a real passion for older bikes and has 2 Orange bikes of his own. I popped down to see him and he said he couldnt believe the condition of it. As the 'Gold' service includes a strip down and clean etc, he said it was unusual for someone to bring their bike down and have given it a clean first. I hadn't!! That's how it came out of the garage.
Anyway, turns out he really does have a passion for older bikes. He's restored a few Orange Clockworks for himself, his father and he did one for his girlfriend. He said it doesn't need the 'gold service' but I said for the extra money I'd prefer to give it a pamper as I feel it deserves it for holding up so well after all these years.
The plan is... full strip, everything cleaned, new (good quality) tyres and inner tubes, taped rims, new break pads that are slightly curved, new cables, some kind of waxoyl for inside the frame, all the grease/oil renewed, outside cleaned gently, the frame waxed and he said he's going to try and source the black 'Clockwork' sticker because the other side of the bike (left side where there are no cables on the top tube) has a few of the letters rubbed off. He's going to take the sensor things off the bike (said I'd be better off using my phone), but leave the crud catchers, Zefal Carbon bottle holder and the bar ends on as he said these are obviously 'of the era'.
Apparently you can get some 'furring' on some of the parts, but he said 'this is coming off with my fingers - I think this is going to look like a brand new bike! Amazing!!'
He brought out his Orange mountain bike that he uses regularly and I've attached a picture of them. I had no idea how far things have progressed, it reminds me of the current mini vs the original and mine looks really cute. He's such a lovely chap and incredibly passionate about both old and new bikes, but he openly admits he has a real soft spot for old 'british' bikes. His name is Mike at:
