This Specialised Aethos fixie is the good bike we have seen this yr

What occurs whenever you put an knowledgeable Aethos within the fingers of the model’s fanatical designer, Erik Nohlin?

That is it – a captivating mounted gear conversion designed and tailor-made for long-distance randonneur rides, all based mostly on the 585g S-Works Aethos body, full of disc brakes, dynamo lighting, rack and 3D-printed saddle.

It is a bike that speaks to Nohlin’s love of fixed-gear driving – “no different type of biking can put me in such a deep state of meditation,” he says, and likewise pays homage to his pal Metin Uz, who died in Could.

Nohlin advised BikeRadar: “As I attempted to make sense of this tragedy, I noticed that the perfect factor I may do was proceed Metin’s mounted gear legacy and construct my new random bike in his reminiscence.”

Dubbed ‘Randonnaethos’ by Nohlin, the bike was made doable, partially, by an eccentric backside bracket and a number of residence workshop tips.

This included drilling the seat submit to route the dynamo cables (warning: this can void your guarantee!) – “twisting by the submit, seat submit, down tube and fork” – and adapting Aethos’ present derailleur hanger.

“I machined the derailleur hanger to solely use the highest that indexes the hub at launch,” Nohlin wrote in an Instagram submit (@hellhommus) documenting the construct. “When the usual internal axle slides out of the automobile [hub], the wheel is straight away thrown out by gravity. This offers very quick straight fixation with out the necessity to rigidity the chain or reposition the wheel flat on the body.”

We spoke to Specialised chief designer Nohlin to be taught extra about this extraordinary motorbike, which he calls “an eclectic combine between LoFi and HiFi.”

First, why did you set this construct collectively?

The development of Erik Nohlin started with the Particular 56 cm S-Works Aethos RFP body.

It might appear foolish to make a fixed-gear bike out of an Aethos, particularly when residing in a number of the most mountainous cities in the US – however to me, that makes complete sense. In truth, I felt I needed to.

Within the spring of 2022, because the Tremendous-Randonneur season with the San Francisco Randonneurs got here to an in depth, I had the chance to journey alongside the 600km Mendocino Seashore with my membership’s longtime member, fixed-gear randonneur Metin Uz, with whom I’ve ridden numerous brief distances. years.

Nohlin’s ‘Randonnaethos’ mixed with cautious adaptation of the Aethos framework and thought of element alternatives.
Erik Nohlin

We rode many of the brevet collectively. Simply two weeks later, throughout Treasure Cove 1200 in Virginia, Metin was shot useless about 220 miles from the journey.

Whereas attempting to make sense of this tragedy, I noticed that the perfect factor I may do was proceed Metin’s legacy of mounted gear and construct my new bike in his reminiscence.

What was your inspiration for the manufacturing?

Specialised launched the Aethos in 2019 as a spherical tube antidote to the aerodynamic-inspired bikes widespread on the excessive finish of the market.

It is a story in itself. I as soon as had one other Aethos – for a day. It was the flagship of my bike assortment – a very ridiculous bike that I painted and constructed myself for the 2019 Chris King Open Home exhibition.

Based mostly on Aethos Founder’s Version [limited to 300 bikes at launch and the lightest Specialized Aethos build on offer at 5.9kg– ed] and all the things was custom-made and curated to be my “bike without end”.

That is precisely how I spoke to a member of the biking press on the morning of the launch. I introduced dangerous luck Just a few hours later, on my first journey, a reckless driver making an unlawful U-turn hit me and the ultralight bike exploded beneath me as I T-bone right into a Honda Civic at almost 50km/h.

I got so messed up that it kept me off bikes for a full year and, once ready to even consider building a new bike, the global supply chain issues that we all felt prevented me from getting a replacement frame for almost another full year.

Me getting back onto bikes after a long stint of psychotherapy coincided with Metin’s death and I decided that it was now or never. Either I fought to re-establish my love for the distance, or I was just going to leave it there.

The fine people at Specialized Retail Care were able to find me a frame and, during the autumn, I’ve slowly been collecting parts to build another ridiculous, but very different Aethos.

Can you talk us through the key component choices?

Erik Nohlin

The frameset is the S-Works RFP (Ready for Paint) in a size 56. This means satin-cleared raw carbon with the decals on the outside to allow for custom paint.

As this is a bike built for the ultra-distance, a dynamo setup was a must, and I already had a Son hub and a Supernova light setup from before. The 28-hole hub would make for some very strong wheels. Not the lightest, but very strong.

I opted for some low-profile H Plus Son [TB14] rims to get some traditional class. The dynamo is internally pushed. The rear hub is the legendary WORD mounted gear hub from my buddies at Paul Parts, once more 28h [the Wacky One-Speed Rear Device – WORD – was the first purpose-built singlespeed mountain bike hub when it was released in 1996 – ed].

First of its variety on the time, this traditional hub is a really prime quality hub that allowed me to run disc brakes, which was a should for me.

A Dynamo-equipped Aethos? Make certain! It is a SONdelux hub.
Erik Nohlin

The appointment bag is from the gathering I designed in collaboration with Specialised and Swedish model Fjällräven, consisting of a evenly assembled freestanding shelf and an 8-liter bag that matches all the things I want for even the longest journeys.

The saddle is a 3D printed Custom-made Romin Evo and the cranks would be the most particular half of all of them. In 2012 I took half within the first Intercontinental Race from London to Istanbul with these cranks on my belt pushed AWOL.

Erik Nohlin

It isn’t fancy or gentle in any respect, however we have been by heaven and hell collectively, so I assumed we would proceed that theme on this new bike.

Lastly, what prompted me to put in a inventory Aethos mounted gear is Phil Wooden’s eccentric backside bracket.

The 28-hole hubs entrance and rear present very robust wheels.
Erik Nohlin

What gear are you operating in?

This Phil Wooden Philcentric backside bracket allows mounted gear conversion. Based on Phil Wooden, a element producer based mostly in San Jose, California, the outboard backside bracket offers “eccentricity with out using horizontal drops, eccentric hubs or chain tensioners.”
Erik Nohlin

The eccentric decrease hub permits me to get right into a heavier gear than the 46×18 I presently have with out shortening the chain.

46×18 is a whole compromise for me. I am often a robust rider in a heavy gear, I journey quick, however there are at all times just a few climbs on our native routes, forcing me to decide on a lighter gear now.

Nohlin makes use of 46x18t gears.
Erik Nohlin

It additionally forces me to drive slower and switch greater than I am used to however hey, that is the fantastic thing about exhausting gear random beginning. It is you and the bike, and the surroundings determines your velocity.

That is what I like in regards to the fixed-gear drive, the direct drive, and the hyperlink to the asphalt. No different type of biking can carry me into this deep meditation.

What’s it like to make use of disc brakes at a mechanic?

TRP Hylex brakes present the stopping energy. “I spent an entire season on a brakeless fixed-gear bike and I’ll by no means try this once more,” Nohlin says.
Erik Nohlin

A should for me today. Particularly when driving with others.

Again in 2009, I spent a full season on a brakeless fixed-gear bike and I’ll by no means try this once more – enjoyable however foolish nonsense!

Hylex is a single velocity disc brake system.
Erik Nohlin

TRP Hylex brakes permit me to journey safely and considerably cut back the stress on my knees when going downhill and braking.

At 44, my knees are extra delicate to emphasize than earlier than, and disc brakes permit me to loosen up and deal with the journey in a means that no brakes would.

TRP calipers – not that you realize.
Erik Nohlin

What’s the ultimate weight of the bike?

6.66kg, of course.

If you follow me on social (@hellhommus) you know that my Black Metal addiction and fascination for the dark arts, forces me to say that…

In reality, I’m not sure. The bike is not built to be a weight weenie. I bet I could have gotten it below 5kg, but with the dynamo lights, rack and crank setup, I bet it’s closer to 7kg. Funny how the front hub and disc weighs the same as the frame (585g).

What I wanted to achieve here was a bike that is incredibly comfortable for the distance, while also being trustworthy.

My previous Aethos was one of the most comfortable bikes I had ever ridden and when you find a bike that fits you that well, that’s a great start for making it even better through smart component selections.

What riding are you planning for the bike?

Well, there are so many rides I haven’t done.

First, I guess getting [the Aethos] On the outdated roads of our pal Metin in Marin and Mendocino counties, however then who is aware of.

Anticipate Nohlin’s 28mm Customized Turbo Professional T5 tires to go a good distance subsequent yr.
Erik Nohlin

I hope there shall be extra PBPs [Paris-Brest-Paris, the 1,200km long-distance event from the French capital to the Brittany coast and back] and a brief distance of 1,200 km sooner or later, however I’m humble about my very own vulnerability, so it is sensible to deal with one journey at a time.

There is a race left with the San Francisco Randonneurs in December and I hope I can premiere the bike there.

The rest you need to inform us in regards to the bike?

Nohlin drilled the Roval Alpinist seat submit to offer inside cable routing for the Supernova E3 2 taillight.
Erik Nohlin

As a Specialised worker, I ought to level out that drilling any half will not be really useful.

Not solely will it void the guarantee, however it may also be harmful.

Dynamo wiring “crimps down the mast, seat tube, down tube, and fork”.
Erik Nohlin

As a professional I’ve executed some carbon customizations to attach the dynamo lights internally, however I would not advocate it.

I hope a few of you’re impressed by this construct. I do know that hill climbing is fairly large within the UK and it is one thing I do actively too. This bike can turn out to be much more ridiculous on a hill-climbing construct.

Total, I invite you all to assist hold the mounted gear format alive. It’s an extremely pure and timeless kind of motorbike.

And at last, are you glad with the ultimate product?

“I like the eclectic combine between LoFi and HiFi on this construct,” Nohlin says. “The world’s lightest manufacturing body and a dynamo hub… That friction is superb!”
Erik Nohlin

Sure, it is actually thrilling. It goes on like a dream. An unbelievable bike.

It is nice that small unbiased components producers like Paul and Phil nonetheless care about excessive bike cultures and freaks like me. They play a significant position in making biking extra expressive.

Titanium cages and Maurten bottles full the construct.
Erik Nohlin

I like the eclectic combine between LoFi and HiFi on this construct. The world’s lightest manufacturing body and a dynamo hub… That friction is superior!

I do not actually like naming my bikes, however Randonnaethos has turn out to be a hashtag posting in regards to the course of, and you could find extra particulars on Instagram beneath.
