Featured Bike: Retro Gravel! JOM’s Vitus 979 L’Eroica Bike


L’Eroica started in 1997 because of one man, Giancarlo Brocci. Giancarlo admired the values of a past cycling so much that he wanted to reconnect others to the heritage that inspired much Italian history; literature, culture, and music.


L’Eroica also began as a foundation for the protection and preservation of the last gravel roads in Tuscany. These romantic concepts led to the idea of L’Eroica, an event that initially saw 92 participants, or “hunters of feelings and emotions”, as the creator Giancarlo Brocci names them.

You can read more about the experiences of the Gravel Cyclist crew at the 2016 L’Eroica in Italy, below:

(Part One) – (Part Two) – (Part Three, The Ride) – (Part Four, The Video). There’s also plenty of retro bike goodies from the event – Retro Bikes Part OneRetro Bikes Part Two.


L’Eroica has strict requirements on bicycles – in a nutshell, they must be a road bike – although I did spot a few Alan CX bikes last year – that aside, pre-1987, downtube friction shifting, exposed brake cables and toestrap pedals.


The technology from this timeframe is so different from what is available nowadays. Steel frames were the norm, as were large and very limiting gear ratios, typically consisting of a five speed freewheel. Quite the departure from 11-speed electronic drivetrain systems with hydraulic disc brakes!


With that said, I wanted to build a bike that was trended towards the upper end of technology during the late 1980’s. I’m a long-time Sean Kelly and Phil Anderson fan, but considering I had a Vitus 979 frame and fork laid away as a future project, that made the choice easy – build a Sean Kelly Team KAS replica for L’Eroica.


The Vitus 979 is constructed from the company’s Dural aluminium – it also one of the few aluminium frames that is accepted by the L’Eroica organization. The frame’s lugs are aluminium too, and the frame tubes are effectively screwed into the lugs and glued. At the time, this was cutting edge technology.


The technology wasn’t perfect, and over the years, the bonds on many of these frames has failed. Thankfully, the example I have has been well looked after and is a size 54 – not quite as flexy as the bigger frames.


The components on my Vitus 979 aren’t quite period correct, but they are reasonably close. Team KAS was supplied by Mavic components. At that time, Mavic was a supplier renown for reliable and reasonably lightweight components that were completely rebuildable. I set about building the bike as close as possible to how Sean Kelly would have raced it, but with a few allowances for some modern conveniences.


On event day, I chose Clement’s Strada LGG in 700c x 28mm – thank you Clement for supplying the tyres! – These are the clincher variety, whereas when this bike was new, they would have been tubulars.


The rims are HSon Plus TB14’s, which mimic the low profile nature of aluminium rims, the norm at that time. Hubs are the 571 variety by Mavic, but these are cassette hubs, and the last of the line. Mavic still produces hubs, but the 571 series was the last they ever sold as hubs alone.


Above, the Vitus aluminium fork and 32 spoke, 3 cross front wheel.


On the rear wheel, the matching Mavic 571/2 hub – not of the freewheel type, but a cassette. This allows me to use these wheels on other project bikes, and not just dedicated to the Vitus. For L’Eroica, the wheelset was fitted with a 7-speed 13-28 cassette and 8-speed chain.


Not exactly the period correct derailleur, the Mavic 840 works fine in friction mode but was originally built for Mavic’s 7 and 8 speed index system. I just couldn’t bring myself to use my mint / new old stock Mavic SSC derailleurs.


The Vitus 979 frame is designed for 7 speed systems, and thus is spaced for 126mm at the rear end. However, the properties of aluminium allow me to stretch just a little, and fit the Mavic 571/2 hub, which is intended for 8-speed / 130mm spaced rear ends.

vitus979-2017-42Pictured above are my period correct derailleurs for a Team KAS Vitus. I just need to find some examples that aren’t in such primo shape… this is the problem with collecting cool components :mrgreen:
vitus979-2017-13The classic Mavic 631crankset  isn’t period correct either, but this crank features 130BCD, which allowed me to fit a very rare set of genuine Mavic 50 / 38 chainrings. Thus, I would have marginally lower gears than most at L’Eroica. 53 / 42 was the norm for a bike of this period.
vitus979-2017-17The Mavic 631 is commonly referred to as the “Starfish” crankset.
vitus979-2017-12The only difference between this Mavic 862 front derailleur and the one pictured earlier, is the lack of SSC coloring on the derailleur body. Restoration purists would scoff at this, but I was after function.
vitus979-2017-18 vitus979-2017-14Mavic 640 pedals with Campagnolo medium cage and Alfredo Binda straps. This is a very secure interface, but not quite as convenient as the modern clipless pedals we are all so used to.
vitus979-2017-29As I found out first hand at L’Eroica, it doesn’t pay to lock your feet down at maximum tightness using toestraps. I had sore and numb feet by the time the 209 kilometres of L’Eroica was over.

vitus979-2017-40Retro bikes and pedals need appropriate retro shoes, and I got lucky finding a pair of genuine Adidas 3-Stripe Eddy Merckx shoes. Love them!

Above, the shoes are fitted with a modern insole to make the fit a little better, and new old stock nail-on T.A. aluminium cleats. Yes – nail-on. Once you determined your position with the cleat on the sole, you nailed them down. However, I cheated a little and used very small brass wood screws – much better than nails.
vitus979-2017-11The business end of shifting – Simplex friction downtube shifters.
vitus979-2017-35These work well and in my experience, didn’t slip.

vitus979-2017-6Since these photos were taken, the brake levers have been replaced with so-so conditon Mavic SSC brake levers (which are rebadged Modolos). We are spoiled nowadays by the anatomic shapes of modern brake levers. The Modolos are difficult to operate from the hoods.
vitus979-2017-7Genuine Mavic 360 quill stem, another very rare item.
vitus979-2017-34Mavic 305 headset – not quite period but much easier to obtain than the Mavic 310 headset. If anyone reading this has one available with the installation tool, please contact me.

vitus979-2017-5The Speedy Modolo brake has reasonable braking power, once you toe the pads in. Ideally, these will be replaced with Mavic SSC brakes in the future – readers, please contact me if you have some laying around for sale!

vitus979-2017-39For those who have built up a Vitus 979, you’ll know how tricky it can be to route this cable, particularly if the previous owner didn’t leave a brake cable in place when you acquired the frame!
vitus979-2017-27The Vitus 979 relies on a 25.0mm seatpost. Seatposts from that time were typically 20 – 40mm shorter than the usual 250mm length posts we are used to. The American Classic 25.0 seatpost pictured above is one of their last ever Ohio-made posts, and features very thick walls. Bill Shook of American Classic informed me a person of my weight could run it right at limit without worries of a breakage – but it isn’t recommended.

The L’Eroica experience was amazing, and my BEST day on a bicycle – ever. It also gave me a true perspective into how hard the professionals from the 1980’s and before were. The equipment they used was often less than optimal for the task at hand. And, many of the European roads from earlier times were gravel – including all of the Grand tours and not so grand races.

    Beautiful bike JOM. Good luck to you guys in Georgia

    I actually owned and raced one of these back in the day. Mine was equipped with Shimano components and tubular wheels. I forgot what shoes I wore with the toe clips and straps — maybe Detto Pietro perforated leather. I also recall that it used a special seat post with an internal wedge to prevent slippage. It felt wonderfully light, compared to my Japanese steel bike, but was a real noodle of a frame. Whatever advantage you got from the light weight, you lost because of frame flex. Of course, Sean Kelly- the greatest rider who never won the World Championship or the TdF- won virtually everything else on this bike. But, rumor had it, that Kelly’s bike was reinforced with internal steel rods to increase the frames stiffness. This is not a bike I missed very much.

    • JOM JOM

      Kelly won Milan San Remo on the sort of improved 992 model… he descended the heck out of the Poggio to catch and crush Moreno Argentin in the sprint. I will say, the frame was very comfy at L’Eroica, but I stayed seated virtually the entire time!

      • Avatar Bobk

        One of the most incredible classic race finishes of all time. Both Kelly and his Irish countryman Stephan Roche were great descenders. I had the great honor of riding and conversing with Roche at his old fart training camp at Mallorca many years ago. Roche could mesmerize us with stories of life in the pro-peleton. And, boy — could he descend on the tricky mountain passes in Mallorca.

    I had a Vitus as well back in the day but the bike that I raced the hell out of was an Alan of similar construction. Retrofriction down tube shifters where great also. Mavic GP 4 tubs laced to Campag hubs too. Beautiful bike Jayson good luck in GA see ya at the heartbreaker.

    • JOM JOM

      Big Head Todd has the Alan… I have always loved how these two brands looked. You probably know this already Biron, the Alan was licensed to a bunch of different manufacturers.

      See ya soon!

    Beautiful bike Jayson. Now I really want to build up something cool like this, look what you have done, haha! I had an old Olmo in college that I never should have gotten rid of. I’m just a sucker for steel bikes (stainless too ;).

    Wonderful post and fantastic job on the bike! I have a Vitus 979 (pictured here: https://www.flickr.com/photos/79189661@N07/11700166264/ ) and have been wondering how wide of a tire I could put on it. In fact I was looking @ Clement Strada so am very curious as to how they fit on the bike. Your spec says you’re using 700c x 28mm, but one of the pictures shows 700c x 25mm. Can you confirm that both fit? Is the stretch in the frame to accommodate the wider hub needed to fit either 25mm or 28mm wide tires? I have the regular sized hubs for my Vitus. Thank you!

    • JOM JOM


      I had 25mm tyres fitted for those photos, but ran with the same tyres but in 28mm at L’Eroica. The frame stretched enough with no worries to accommodate a 130mm hub. It probably isn’t recommended, but I know of others who have ridden their Vitus 979’s with 130mm rear wheels for years.

      Good luck!

      • Avatar Calvin

        Thanks for the reply! Do you think the 28mm would fit on a frame that isn’t stretched? Or should I stick with 25mm? I’m not upgrading my hub to 130mm.

        • JOM JOM

          That will largely depend on your rims and tyre choice, but I had plenty of clearance. Remember, there’s no stretching happening near the bottom bracket area, rather it happens at the dropouts. I’m running the Hson Plus rims (for the retro look), and they are wide, but the Clement tyres I ran size up a little narrow. But if in doubt, go 25mm.

        • Sorry this is more than a year later, but I’ve run Clement 28s and Panaracer 28s with no problem on my stock 979 with Mavic MA40 rims.

    • JOM JOM

      Superb! I am certain I was the only 979 rider in 2016, especially with a full Mavic groupset. I did see a few Alan bikes, good to see some aluminium love out there. I would like to return to L’Eroica again in the future. My BEST day on a bicycle – ever.

    A nice build ,but the amount of seatpost is way too modern for a vintage build . (see Shaun Kelly )Back in the day this frame would have been too small, but a a great looking machine.

  8. Avatar Colin Bartlett

    I’m thinking of getting a Dural 979 in the near future. Couldn’t afford one in my younger days but have always wanted such a steed. Is there a lot of frame flex with these? At the moment I have an old Peugeot Europa which is extremely rigid (and heavy). All advice from you gentlemen would be very much appreciated.

    • JOM JOM

      Hello Colin, on the bigger sizes, yes, there is flex. I had no problems with this smaller example of the 979.

      • Avatar Colin Bartlett

        Thanks for the quick reply, JOM. The size I’m thinking of is 55cm. Yours looks to be a bit smaller. Problem is I can’t try before I buy. Thanks again.

    I was in Bici L’Eroica (Italy) in 2013, to made the Granfondo 209Km. I want to return with a 979 Vitus, a replica from a Portuguese team (Sporting Clube Portugal) of 1986. It’s almost finished. Mounted in Mavic SSC1000.

    • JOM JOM

      Thank you Carlos, I would love to see photos of your 979 when the build is completed.
