Dirk Dekeyser – Life as a Bike Mechanic


We spoke to circuit spanner man, Dirk Dekeyser at the Grenoble Six Day. Who makes sure the wheels turn smoothly during a Six Day race? The mechanics are the men who change the gears, stick on the tyres, endlessly polish the paintwork and pick up the pieces after crashes.

They arrive first to build the bikes up and leave last after having stripped the bikes down for transit. What makes a man want to roam Europe, often driving a thousand kilometres through the night to get to the next race – or to get home?

Dirk Dekeyser
Joerg and Dirk (R) take a two minute breather.

Your shop in Drongen, Gent is a family business, Dirk?

“My great grandfather started the business in 1920, he built his own frames, back then. My grandfather ran the shop until 1988 and then I took over.”

Were you a cyclist?

“No, I played football!”

How did you get into race mechanicing?

“The Belgian national coach and former Six Day man, Michel Vaarten asked if I would help the national squad mechanic at some track World Cups and then the track World Championships – it led on from there.”

How many Sixes have you worked?

“I’m not really into statistics, but I started 1999/2000. I think the first Six I did was Berlin?”

Typically, how many riders do you take care of?

“Sometimes just two; at Berlin I only had Michael Mørkøv and Alex Rasmussen. But here at Grenoble in 2009 I had eight. I mostly look after Belgian, Danish and Dutch riders.”

Do you work on the road, too?

“I help the Belgian pro team Topsport Vlaanderen; they have staff mechanics but if their programme is heavy then I’ll come in on a ‘daily’ basis.

“Recently I did the Circuit of Lorraine and Bayern Rundfahrt for them.”


“No, I don’t really like the behaviour of a lot of the fans at cyclo cross races – throwing beer at riders. Imagine if they did that at a Six !”

Mountain biking?

“Just to watch; I have a couple of guys who work in the shop and they are crazy about it.

“We stock mountain bikes, it’s a part of our business.”

What’s your favourite part of the job?

“Working with the bikes – when I’m in the shop so much of my time is spent on admin I don’t really get the opportunity to work on bikes at all.

“But here you’re working with them all the time – that’s what I really enjoy.”

Dirk Dekeyser
Dirk helps the riders in other ways – here pushing Cam Meyer off in a Derny race at the Berlin Six.

And the worst?

“The travelling; I have 1200 kilometres to cover to get home after this.”

You must have seen a lot of changes in equipment?

“It was steel frames when I started but then aluminium came along – many of those weren’t any lighter than the best steel frames.

“Then it was the time of carbon – it’s all commercial and nowadays things evolve fast.

“The big selling point with the first carbon road frames was that they absorbed the road shock – but now they are always making them stiffer.

“And the integrated seat post design makes them even more rigid – you need a massage after every ride on one of those!”

What get hits hardest on a Six Day bike?

“Tyres and handlebar tape; in the old days the headsets took a lot of punishment but now, with the integrated system, I can’t remember the last time I changed one.

It’s not like the road where a lot of dirt and water is flying about.”

What’s your favourite equipment development?

‘Shimano Di 2 electronic gearing – it’s amazing, Japanese precision at it’s best.

“I like the BB 30 bottom bracket system, the axle is shorter, there’s a narrowerer ‘Q factor’ (overall width of crank faces) and it’s much stiffer.

“The 1.5″ lower with 1.125” upper head race system is good too, much stronger.

“And now there are asymmetric chainstays – it never stops!: Focus now have a rideable bike with off the shelf equipment, which is less than five kilos.

“Hushovd’s Cervelo frame is just 800 grammes. I think that the UCI should look at the minimum weight restrictions, the light equipment is safe, now.”

Do Continental tyres still rule the boards?

“My guys are on them – Danny Stam rides Vittorias, they sponsor the team and the Swiss guys ride Schwalbes – but I still like the Continentals.”

Who’s the fussiest rider?

“Michael Mørkøv; he sees everything.

“I hate when the cabins are laid out so that the riders can see the bikes, Michael sits and looks at his machine all the time – he always sees something.

“But that’s part of the reason why he’s so good – that professional attention to detail.”

Dirk Dekeyser
Dirk shoots the breeze with Alex Rasmussen.

Who just let’s you get on with things?

“The older guys, they know I’ll take good care of their wheels and tyres and that’s the main thing.

“The young guys are into things looking good – white saddles and stuff like that.”

What do you like least about the circuit?

“The crashes; I was there when Isaac Galvez had his fatal crash at Gent… my rider, Dimitri Defauw – who is sadly dead now, too – was involved in the crash.

“I had to walk past Isaac to recover Dimitri’s bike – I’ll never forget looking down at him as he lay there.”

What do you like most about the circuit?

“It’s one big family, there might be different mechanics and soigneurs looking after different riders but it’s all one little world.”

The mechanic’s job is never done.

There’s a postscript – as I helped Dirk carry the bikes up to his camper van at wearing on for 02:00 am on Wednesday, he turned to me and said; ‘for the interview, when you asked about what I don’t like – I forgot about this bit !’

We were spoiled at Strasbourg those first two days of Le Tour de France 2006 with the hotel just a couple of minutes from the press room and the action all within easy reach until the start on Monday. The driving is a killer now en route Saint-Quentin, not just because it’s boring and tiring but because of the time you waste. If I do a Grand Tour again, I’ll definitely organise a driver so as I can write as I travel.

Robert Millar – Let’s give the guy his dignity

"Elusive cyclist (Robert Millar) is rediscovered as 'queen of the mountains' "- so says the headline in the Sunday paper, The Star? The News of the World? The Sport? No, it's our "quality-read" for the sabbath - Scotland on Sunday. Whilst George Best drank himself to death, and as "Hurricane" Higgins trots down the same trail, many of the gentlemen of the press struggle to conceal their admiration for these 'lads'.

On a typical Scottish spring afternoon of ‘Four Seasons in One Day’ Herbalife/Leisure Lakes’ talented 18 year-old English rider, Harry Tanfield fully justified the ‘Elite’ stamp on his license to win Kennoway Road Club’s David Campbell Memorial Race over 80 tough Fife miles around the Cults Hills. With 2013 results which include, 10th Heist Op Den Berg; 2nd Evergem Belzele and 8th Tourinne-Saint-Lambert Kermises in Belgium, Tanfield’s win would have come as no surprise if we’d done our homework.

Giro d’Italia 2008 – Day 3: Stage 15: Arabba – Passo Fedaia/Marmolada

"The best laid plans of mice and men gang aft aglay," Rabbie Burns must have had a premonition about the Giro when he wrote that. It should have been a short hop over the Pordoi Pass from the digs to the start at Arabba to Marmolada. The jobsworth policeman at the top of the Pordoi settled our hash though; "No, you stop now, road closed, no journalists, only team cars!" Aye, cheers pal, you'll soon get that job you want in the riot squad, bludgeoning students. Sorry..., I was ranting, wasn't I?

Le Tour de France 2009 – Stage 16: Martigny > Bourg-Saint-Maurice, 159km

Sitting here in Bourg-Saint-Maurice, perhaps I'm going to revise my opinion that l'Equipe's Tour coverage isn't as good as the Gazzetta's Giro coverage. The Gazzetta looks better, but the L'Equipe goes so deep.

Il Giro d’Italia 2014 – Stage 13; Fossano – Rivarolo Canavese, 158 km. Marco Canola Stays Clear

There are two ways to look at this stage. If you’re the best and the rest know that then you just have to get on with it – I can remember HTC setting Bert Grabsch to work with 100 K to go in a Tour stage to keep the break in check so as to set up Cav for the sprint some two-and-half hours later.
