    Thank you to have checked on your own bikes. So I don't need to make an appointment at the eye doctor ! 😄 We can imagine than 'TH' represents a code for the factory or the frame builder. Then '87' should correspond to the year of manufacture (taking into account than these bikes were...

    Hi Andy, You can doubt, for sure, those serial number are difficult to read, I wear glasses, and I've more than 50 years !!! ;) I took a quick picture yesterday, here it is : We can see like a 'T' on the left. It looks engraved. But I will check it another time. It's difficult to see...

    Hi, As promised, I looked for the serial number of my B52. But unhappily I failed to remove the cable guide. The screw is completely blocked and damaged. I put a lot of WD40 and I will retry during the next week-end (the bike is not at my home, as I can't use it as daily commuter for the...

    Hi, Thanks for this information. It is the same size than mine. But it could be used also on PG seat tube (those with 28.6 external diameter and 1.0 thickness) I find the marketing data for the Tange 1200 MTB tubesest (triple butted version, it exists also with double butted). It...

    That's also my understanding... But depending of steel qualities and thermal treatments, a triple butted tubes set could be heavier than a double butted, and perhaps even heavier than a plain gauge (designed for light road usage for example). I will try to find again the Tange 1200 marketing...

    Hi Andy, Thanks for your explanation. For sure I can look for and give you the serial number. I didn't see it when I cleaned & lubricated the bike, but I will search again. It required perhaps to remove completely the cable hanger at the bottom of the bike (sorry I don't know the technical...

    I suppose also that this bike has crossed the Channel in luggage of a young English man that moved to France (or take some holidays here). I didn't find notification of Tushingham bikes in old French newspapers I have (from 1989 for the oldest). On the contrary Muddy Fox was well established...

    Many thanks for your reply. That's confirm we have to find rear hubs in 126 or 130 (max) size ("over luck nut" dimension is the right term) for this bike. You know certainly this document where we can find complete information for the Exage range ...

    Hi, I've just discovered this thread, what a amazing find ! This bike has probably be setup by the founder of Orange bikes itself (at the time he was - if I well understand - the designer and main racer of Tushingham bikes). Great story ! You have done a very good job to put in again on the...

    Hi, Following the "introduce myself" post, here's the bike I like to talk to you ... I was looking for a average/utility bike to go 2 times per week on a new 'proxy' site for my work. I don't want to buy a too much low/entry level bike, and I don't want to use my regular MTB (too much...
