Stronglight 93, 49D, 104, 105 Cranksets
I’d prefer a drilled Stronglight 105 crankset on my bike to Campagnolo Super Record, though many would disagree with me. The great imitators of the day, Shimano, also made a very desirable crankset, the lovely 600 Arabesque, to compete with the best of Europe. However, I just think the iconic Stronglight models, the 93, 49D and 105 look more beautiful, and there is something special about these cranks over the rivals of the same period. Especially, I believe, in the case of the Nuovo Record, which is quite bland compared to this Stronglight model above, the 93. Who cannot notice the striking pentangle design, a stand out feature on any bike?
The 93
Velobase describes the 93 as “Lighter than just about anybody and pretty much indestructible”, which is why I think these cranks are still on many bikes today. I weighed one recently, with its bolts and dust caps, and it came to 618 grams. It may not have been the lightest of all, but it certainly was one of the leaders of the market. I’ve seen some fitted with drilled chainrings, and they look even more snazzy. The 5 arm model graced some of the best bikes of the day, including the Peugeot PX10 and top flight Motobecanes and Merciers, like this Mercier 300 here. The 93 had a BCD of 122, common to Stronglight models, arm lengths could be 165/170/175.
The 105 and 105 ter
The 105 came after the 93, but kept a lot of its looks. It’s arms are thicker and the design and logo on them is slightly different. My less favoured ter version came with black chainrings, which was quite unusual at the time. The 105 weighed 678 grams complete, so it was heavier than its elder sister, the 93, but it was stronger and was able to take a lot of abuse. Later versions of the 105 had a Spidel logo beneath the dust caps. BCD was 122, there were more variety of arm lengths, ( by extensions of 2.5mm ), and threading was either French or standard. These 105 cranks often had drilled chainrings, like the one above. Sold for £35, to a rider in Italy.
The 104
I had never come across one of these before, and I thought it was a just a beautiful thing! A 104 double with drilled chainrings, weighing 634 grams. At first glance it looks like it is a triple, but it’s not; it had 53/44 rings and had standard threading, was in excellent condition for its age and even retained its dust caps, undamaged. I sold this for £65 in June 2016, and it was worth every penny, in my view. The non drilled version looked more like a Campagnolo Nuovo Record, which says something of how Stronglight were looking more to their Italian competitors at this time. 122 BCD, and more often in standard threading than French as this model was being fitted to high end French bikes in the early 1980’s.
The 49D Model Depose
The most celebrated Stronglight crankset, first produced at the beginning of the 1950’s and made all the way up to the mid 1980’s. The pentangle design remains the most notable feature of this crankset, like the style of 93. The one above had had its dust caps replaced, they should have been silver and not black. This 5 arm crank was made in 1977 and had French threading, 14 x 1.25. It weighed around 670 grams, and I sold it for £46 on Ebay. I think this is the best crank to have on a vintage bike, because it has the perfect balance of delicate style and quality of design, the thinner arms and its stamped logo in the centre of the arms were its trademark to four decades of success. 122 BCD, arms of 165/170/175, this crank was French threaded and has to be contender for the best 5 arm crankset ever made.
I have a 73 and a 76 Raleigh Competition. I’m putting together the best of both.
Oddly one came with a 93 but with the Chain Gaurd as seen in the 1974 Raleigh super tourer.
Can I drop the chain guard with different bolts? Which is cooler?
Obviously subjective but “you are the expert” applies here!
It looks heavy to me but also very cool. I’m going with big tires and not concerned about weight
Hi Dan
Love the Competition, sounds like a great project. A picture of your bike would be great to see. For the crank, I’d drop the chain guard, I think it’s better without it, personally. I grew up with the racing bike culture of “lighter is better” and we emulated what the pros used when it came to components. As the Competition is more of a racing bike than the Super Tourer, I would have the 93 without the extra metal. But in the end, it’s really what you think looks best with your custom build. Cheers!
Your image of the Model 104 is actually a 99. It was basically the successor to the 49, with a bcd of 86 mm that could take chainrings as small as 28 teeth. I have one and love it, I’ve used it as a 34-50 double and a 28-38-50 triple.
The 104 was sort of a Campagnolo copy while still retaining the 122 mm bcd. The French held out for a long time against Campagnolo, but eventually caved in like everybody else and began copying them. Another example is Mafac, which switched from its great center-pull design to a Campy-esque side-pull in the 1980’s.
You’re right, I posted the wrong photo there. Thanks for the correction and info!
