Dugast goes tubeless!

Or at least tubeless tubulars, like Tufo:


Regular tubulars look like on the right side. A cotton tube sewed together with a basetape covering and a thread glued on the other side. Added are a latex tube inside. But Dugast is making progress and gluing and adding latex to the cotton so loosing both seems and tubes. Makes the construction better so riders like Nino Schurter and Wout Van Aert can ride with higher pressure but with same grip and plushness. The solution also saves 10% in weight compared to regular tubulars.

Tufo has always done this but with rubber all the way so have been pretty harsh. But who will follow Dugast now when they soon are releasing their tires leading the industry once again?

The Specialized Allez for you


The bike I’ve ridden the most is up for sale. Got new wheels, tires, tubes, cassette, chain and bar tape in the end of last season and now it’s just hanging collecting dust. As my heart seems to dream of Italian things all the time I’m selling this beauty for an older more classic bike.

Are you interested?

Size 52.

Price around 16000SEK. Send an e-mail to me at cerrol.jl (at) for more info and buying. Can be this years best deal if you want a really good alu frame with very good components.

Ösmo for the pancakes

The options today was an epic gravelride west of Södertälje or a caféride from Le Mond to places like Ösmo. As the weather was really wet yesterday and riding with guys without fenders on wet gravel didn’t seem like an awesome idea for me, so slept a bit longer and left for Le Mond.

Like an early caféride the level is very random early in the year we lost a guy already when we left Stockholm city who thought it was too hard. Left was 6 riders who tried to stay together but with some with studs, some with summer tires, some have been riding all winter and some not it became gaps and waiting sometimes. All as a regular early spring ride. But funny (I thought who didn’t get dropped for real) and I’m happy doing rides I haven’t done in a long time.


Kalle rode strong with studs and Karim was happy with his Roubaix roadtires :)


I rode with colour. My new Specialized Deflect H2O gloves was awesome. And I saw the light all the way :D

Was great weather today with around 6° and my Café du Cycliste rainbibs and legwarmers held my dry and warm all the time. Didn’t even needed a windproof west today.

But all good things comes to an end. We got split in two groups, Kalle started to talk about breakfast and that he was tired. My stomach started to question about food. Michael held the speed up. Because we came to this:


Came to the café in Ösmo 10min before the others and could make our bodies happy again :)

Then 3 guys took the train home. Me and Michael rode the hole way and Karim joined us for the first part to Tungelsta. Great ride on a sunday and now I know what to order at the café in Ösmo :D

Le Peloton #73

New day, new ride. Today I was supposed to show Camilla the loop and did so the first half. Then she didn’t feel good and turned back so was just me and Jesper (?) left in the grupetto. Took the shortcut in Älta and caught up Michael at the end. Not my hardest ride but good enough for today and ready for the weekend :)

Also got some more colour on my Diverge. Looked like this after the ride today:


And now after bar tapechange (and drop of almost 80g):


Couldn’t resist when I saw that purple Deda tape last wednesday at ettettsex bikeshop ;)

eTap and Quaremont


The groupset came to Specialized Concept Store Stockholm today. Here is both levers, front and rear derailleur with batteries on a scale. It’s really nice, simple to set up and it got feedback like Campagnolo EPS, but without wires and thumbbuttons. Check my Instagram for a short video: Insta

And if you want to watch a more beautiful video Dires Devenyns is in one showing the bad Belgian roads in a way that at least makes me want to ride them all over agan ;)

Le Peloton #72

When it’s 2° Celsius outside, it’s dark and the rain is going sideways. Then I’m happy not to be alone out riding, happy about knowing there are others to ride with:


Everyone with some neon green clothes except me. I had my green Diverge and a POC AVIP rainjacket in orange instead ;) Sometimes my rainjacket is too warm but in these conditions it’s perfect. We had a visit from the strong Jonas with his Cannondale Scalpel and without fenders. He’s the strongest so when it isn’t possible to go up in front my jacket fixed all the rain that came from above and from the bike ahead of me. Was really hard and while no one managed to keep the wheel of Jonas I was the last one to drop, before we came to Älta. Then Michael caught up me and we rode together for the rest. Magnus who had some problem with his derailleur stopped and took this epic picture:


Finally got to Le Mond for a warm breakfast with Kalle:

Like a child at Christmas everytime it happens. My new roadbike is almost finished, finished enough to be showed, finished enough to have been testridden and finished enough to make the wait for spring way too long…

Not as much colour as last year, not as many gears, not as high wheels, not as light. But the target was a faster, cleaner, simpler but made to go further and be more comfortable than the Allez. I love the future with disc brakes and after many thoughts and non understanding it felt like 1×11 drivetrain was the way to go for me when I live here in flat Stockholm.

As usual every bit on the bike has a thought behind. So let’s spread the joy and wait for spring :D
