First post here. Recently got this beauty from seller in CA. Interesting bike as my Lejeune source told me he sold a lot of Lejeune tandems, but had never seen one like this. (Referring to the mixte diagonals.) He thought it might have been contracted to CADEG which he says built a lot of tandems for various marques. I have seen one other frame like this and oddly enough it was a similar size. It has mounts for a generator and all the little wiring guides, but none appear to have ever been used. It has a DT stop for a band derailleur, but also has DT cable stops for shifter cables. Would seem to indicate a stem mount shifter. Glad they are there as I am going to barcons on it. It had the small hanger for the front fender (hangs off brake center bolt) but no evidence of fenders having been mounted. Originally 650B, it had 26 x 1.5 on it when it arrived.
Planned mods: Custom stem riser adapter to allow use of threadless style stems and some Nitto bars I already have. Aero brake levers and the aforementioned bar ends. Staying with MAFAC calipers as it is not going on any hilly treks. Looking for an alloy seat post for the captain and plan to shim a later stoker stem (and a cushier seat) for the boss. Wheels will be Shimano 105 7spd cassette laced 4x to Velocity Synergy rims. Considering two derailleur options. I have a set of Simplex Super LJ or I may obtain a Cyclone GT long cage as it has a Cyclone FD mounted.
Looking forward to the first ride. More importantly, my wife is also.
