  • Campagnolo gears
    with the gear it works as follows the top of rear drop outs are notched and these coincide with notches on the axle There is no chain tensioner at all as the gear is changed the wheels walks backwards and forwards to keep the chain relatively tight How on earth does this work I hear you say As you can see a rod goes up alongside the chainstay and has a lever at the top not unlike a QR lever which is appropriate as it happens The gear is changed as follows First make sure that there is no one riding in front or even worse watching from behind Reach down to move the lever on its first part of travel which will then release the tension holding the wheel in the frame The next part of the lever travel moves the gear selection fork which can be seen astride the top of the chain Now pedal backwards because the striker is on the top of the upper chain whilst moving the lever to select a higher or lower gear If you select a lower gear then the wheel will have to walk forward along the notches to accommodate the larger sprocket When this is done move the lever back to its original position to lock the wheel Breathe a sigh of relief and start pedalling in earnest again For a higher gear that is to a smaller sprocket the wheel will have to walk backwards to take up the slack Detail of the business end of the gear showing the serrated rear end of the frame You may have already guessed that I am an armchair expert as I have never ridden one of these gears but I suppose that goes for 99 9 of us The Paris Roubaix

  • Campagnolo front changers
    changer image below was added to the Gran Sport Group in place of the above gear often referred to as the matchbox changer This early Record had the long arm with cable stop which can be seen below This enabled a short length of outer cable to be used between it and a cable eye clamped to or brazed onto the frame down tube see bottom of page It would also be possible to use outer cable from the lever to the changer but I have never seen this done The cable stop was removed in 1967 when Campagnolo introduced the clamp on bottom bracket cable guide which allowed an open cable run without use of the outer cable The modified Gran Sport was re introduced in 1963 as a Campagnolo budget changer in black and in 1964 as the Valentino another budget front changer General overview of Campagnolo model production of this era as a guide 1946 Corsa and Super introduced 1949 Gran Sport introduced 1951 Cambio Corsa Tipo Paris Roubaix Gran Sport produced 1952 Gran Sport Extra Sport produced 1961 Sportman introduced 1963 Record introduced 1964 Valentino introduced 1967 Valentino Super Nuovo Sport Nuovo Record introduced 1968 Valentino Extra Sport Extra introduced 1970 Gran Turismo introduced 1971 Velox introduced 1973 Production of Record dropped 1974 Rally Super Record Nuovo Gran Sport introduced 1982 Gran Sport Rally introduced 1985 C Corsa Record 1987 Production of Super Record ceased Kevin Sayles has a definite preference for obtaining old Campag stuff and in particular Record front mechs My collection of Record front mechs is almost complete I need one of the very first type the one with the screws holding the bronze arms I used to have one of these it was on a Winter bike back in the late 70s and had seized a little so that when I needed to go back on the small ring I had to take my foot out of the clip and whack the gear with my foot I also need an example of the 11th Generation as listed below Here is my list of front mechs which I believe to be in order of production With images from Kevin below the table 1st Generation chromed bronze arms retaining screws larger triangular body flat cage cable stop without slot still looking for one of these 2nd Generation as above but no retaining screws still with larger body c1959 60 2A Generation A later addition to the sequence The same as 2nd generation but with a slotted cable stop 3rd Generation A later addition to the sequence The same as 3rd generation but with chromed bronze arms 3A Generation alloy arms smaller triangular body cable stop with slot flat cage c1963 4th Generation as above but no cable stop flat cage c1967 5th Generation newer body with protrusion on corner of triangle alloy arms NO CIRCLIP my latest find c1971 6th Generation as above but with the circlip Still flat cage same period as 1st

  • Campagnolo bar-end levers - servicing and fitting
    the Chief Constable points out that no self respecting person would be seen with the cable taped this way even with a Cyclo lever It looks as if Bob had to ride with his left hand glued to the handlebars as fitting punishment Roger Pratt Cardiff Ajax says I enjoyed the piece on the Campag bar end levers as I used these for racing in the early sixties and for their time they worked well as I remember Their use was partly fashion Rik van Looy was a hero the Emperor of Herentals but primarily when we were using close ratio rings 48 52 with only five sprockets six from 1966 maybe 14 16 18 21 24 you almost always had to make a double change using front and rear mechanisms simultaneously to get a manageable gap between gears The double change could be done with down tube levers if you were dexterous and had prehensile fingers but it felt safer and easier with bar end levers If it was good enough for Rik it was good enough for me I feel that these levers were used mostly by Belgian Dutch riders where you couldn t take your hands off the bars much because of cobbles and poor road surfaces Safer when bunch sprinting too I guess that looking back it was probably a slow change given the length of the cables but I don t recall any great problems and the cables HAD to be taped right back up towards the stem for that Flemish pro look I enjoy the site even though I have no great desire to go back the old equipment days but it all brings back happy memories Keith Body puts the case for the other side where function rises above style I just saw the bit on handlebar controls I was a user of these from 1950 at first the Cyclo and from about 1955 Campagnolo All our bikes still have them although sadly rarely used First the picture of Bob Maitland above showed almost the most effective way of fitting the cable Unfortunately these controls which were expected to work even in the wet must be fitted with the least number of bends in the cable and the less sharp the better Bob was right Tie them up to the bars and put a tight bend in by the stem and you would rarely get bottom gear as the Cyclo gear depended on the spring in that direction We also bent the Benelux arm and cage so that the top roller was nearer to the wheel when on the large chainring so that the extreme gears were available I used to bend them to cover 6 speed block produced by putting the top pair from a Regina on a Simplex 5 I used to change both at once off the saddle on any hill unlikely with the Campagnolo GS Also changed both at once with a left hand handlebar control and a Paris

  • 'Clangers' / front changers
    I don t know the date of this photo but from his appearance I would hazard a guess it was taken in the mid 50 s Many riders continued to use manual changers into the early 60 s Jean Robic with Simplex rod front changer which appears modified with cable from a bar end changer I have Included details of the three pre war tours when deraileurs were used for the first time purely out of interest The tour was suspended from 1940 until 1947 However two French tours were run durung this period Le Circuit de France and La Ronde de France along with the Tours of Italy Spain and Switzerland but I have no pictorial evidence of whether or not double chainwheels and front changers were used Tour de France Timeline 1937 Lapebie wins using a Super Champion rear deraileur with single chainwheel 1938 Bartali wins using a Vittorio Margharita rear deraileur with single chainwheel 1939 Maes wins using a Super Champion rear deraileur with single chainwheel 1947 Jean Robic wins using Simplex Tour de France rear and Simplex Competition front changer 1948 Gino Bartali wins after a 10 year gap due to the 2nd world war Would he have been the first rider to win 7 tours We will never know He used a Campagnolo Cambio Corsa on the rear with a Simplex Tour de France on the front 1949 Fausto Coppi wins using Simplex Tour de France rear and Simplex competition front changer Apparently the Simplex manufacturers paid him a huge amount of money to win this Tour The following year he was back on Campag 1950 Ferdi Kubler wins using Simplex Tour de France rear and Simplex competition front 1951 Hugo Koblet shown right winning time trial stage in the Tour de France scores the first win on Campag Gran Sport cable operated front and rear using double handlaebar end levers 1952 Fausto Coppi s second win using Campag Gran Sport with double down tube levers 1953 4 5 Lousion Bobet wins using Huret Tour de France rear and Huret manual front changer Huret did offer a cable operated front changer in 1955 and I think Bobet may have tried this set up on a couple of stages 1956 Roger Walkowaike wins on Campag Gran Sport 1957 Jacques Anquetil scores the first of his five wins and is the last rider to win using a manual front changer see Derek s Gallery He uses Simplex Tour de France rear and Simplex Competition front THE END OF AN ERA Many riders continued to use the manual changer into the early 60s Derek would welcome any comments or extra information and can be contacted via the webmaster Above Cyclo front changer with Campag Corsa rear with fork on bottom chain run Left Campag Sport front and Paris Roubaix rear changers on Serse Coppi s 1950 Bianchi Note the slack chainline especially on the left image The P R gear could be set to give varying chain tensions

    wing and track nuts plus their range of 2 3 and 4 speed gears At a time when probably 90 of club cyclists used fixed wheel Cyclo were producing an 18 gear option involving a hub gear 3 speed derailleur and a double chainwheel which gave the rider a range of gears from 28 to 118 This set up would no doubt be used by the serious touring cyclist who would possibly spend time on Alpine passes whilst fully laden with luggage and camping gear They advertised the Olympic gear in 3 and 4 speed options as well as the Oppy and Ace in 3 gear mode only Also they announced their new gear the Benelux with 3 4 and 5 speed options At the same time Cyclo were producing down tube levers bar end levers plus a twist grip control Cyclo Benelux Mark 7 introduced 1957 front rod operated and rear changer fitted to Ephgrave An advert for the 1951 Cyclo Benelux proclaiming proudly their wins in the Tour of Britain for 1951 and 1952 This model introduced in 1950 operates by a pull chain similar to the Simplex Tour de France Below from Bryan Clarke is a very
