Just acquired a Mercian Pro Lugless Time trial frame with this unusal tubing. A Mercian Pro lugless has been something of a holy grail for me since I first saw one in the flesh back in 2002, but to acquire it in a TT frame (something I was missing from the fleet) it was like winning Bingo night. Shame its in my least favorite colour - yellow, but its a bit tatty and needs a respray.
I've owned a frame made of 753, I have certainly seen 708, we have 725 still being made by reynolds, but 731 OS seemed to have lived a short life. Introduced in 1992 but was phased out in 1998/99 due to the mass aluminium boom at the time is what i read.
I've shone a torch down the seat tube and it has spirals. Looking in the BB shell, these 4 ribs look like a four leaf clover at the tube end. Strange, interesting tubeset, weighs 1792g on my kitchen scales... just wonder how it rides?
