Parts drawer dump Campagnolo Front Derailleurs and 1970s – 80s Rarities and Remasters. Parts drawer implies carelessness – in reality the rare-ones were always bagged and kept pristine. 2 Records (customization explained below) Pre-Super Record but I regard the 4 hole model as Campagnolo’s exploration into creating a SR model. The SR group had been growing more complete through the 70s. 1 Gran Sport (1970s) – very rough surface condition – never has been cleaned This clamp (as shown seperated) is the same as a Record so it can be used with any 70s through’87 models if desired. Turn a braze-on model into a clamp-on. Left overs – Tabbed band w/pin removed from the clamp as described below The arm is – stripped. The 4 hole cage Record derailleur with custom clamp is arguably more durable than an original version. The “flawed” reputation of those. Is for the clamp breaking (further description below). Original 4 hole #0104007 1978 model can be by swapping back the cage and clamp body with the 3 hole model. Easily done by releasing the spring from a it’s groove (de-tensioning it) and removing a single circlip. Then sliding the cage and arms off of the body posts. All models are for 28.6mm (1 1/8) seat tube. My take on the “failure” reputation of the 4 hole model – the how and why from observation and guessing (I’m not an engineer). The failure point I saw was the back clamp portion. So stressing events may go like this > cage under shifting forces with help from chain pins catching? > loads clamp body (twisting)> the straight band allows more twisting stress (certainly doesn’t help) > load pass into the back clamp (which has reduced material starting these’78 models) and it cracks. 4 hole derailleur as presented. Clamp body is custom-made from a 70s era (1052/1) swapping in a straight band (see images). There is more material (for style) in that earlier clamp. See side by side and back views – also the “circled” images to clarify. The back extended down further than the later 1982-87 (1052/NT – 0104007) versions. It is trimmed a little on top but is still more substantial than an 80s clamp body. In order to remove the wing-tabbed clamp band it was drilled through the top but then plugged with an alloy cable end – so not very visible (see marked-up image – green arrow). That image also illustrates how older clamps have a wider post section bracing against the frame. 3 hole with straight band. Turns out this was an even rarer combo that actually existed – ref. The band from the 4 hole clamp not very much use – i. Very little chain rub is on the 4 hole cage with a typical 1982-87 3 hole cage – a leftover from removing a braze-on clamp body. Someone at Velobase stated A must have for a 1978 bicycle. More like 1979 in the US. The bike this came off of was a 1979-80 Colnago. Search 1979 Colnago Catalog – there are multiple examples present. I tinkered back in the mid to late 80s. A supply of a parts in the shop where I worked was on hand as left-over broken and separated parts were present. Braze-ons hit the market and swapping front derailleur bodies for upgrades, etc. In 1980 the 4 hole’79 front derailleur was quickly the first part removed from my bike when I experimented with 7200 Dura Ace. So this one has very little mileage. At that time I had no idea of the flawed issue though I did noticed the later reverted three hole and standard band models. At some point back then a broken straight band model came my way so I harvested the band and combined a 70s era clamp to make a “durable” 0104007 version never putting it to use. Further guess about the failures: A complete or “full” Italian bike it had a Regina freewheel and chain – that was the “bad” set-up for the failing stresses. Those chains had protruding pins. The ones that catch into the lower-placed 4th hole. A better combination was a Sedisport narrow chain with flush pins. Campy did sell some 3-hole caged straight band models – see velobase ref. Below Same band with trimmer clamp body. Had they solved the issue of failures? The three hole with straight band as presented – I thought was a bastard combo. It actually existed and maybe is even rarer than a 4 hole model. Info on Campagnolo Record 0104007 (1978, 4-hole) covered here.
