TIME ADHX carbon all-road & gravel bike, made in Europe with plant-based Dyneema reinforcement (2024)

TIME Bicycles unveil the all-new ADHX all-road & fast gravel bike using their unique woven carbon construction reinforced with industry-first Bio-Based Dyneema fibers made from wood manufacturing waste. Calling it their “debut gravel bike”, the new Alpe d’Huez X (ADHX) leans more in an all-road direction with somewhat narrow-for-modern-gravel tire clearances, but it packs a lot of exciting new manufacturing tech into a premium carbon bike made entirely in the EU…

TIME ADHX bio-Dyneema carbon all-road gravel bike

The all-road leaning carbon Time ADHX is a fast gravel bike promising a ‘perfect blend’ of lightweight, power-transfer & handling stiffness, rider comfort, and all-terrain durability – all tuned for limitless mixed-surface riding.

It gets a unique high-performance blend of carbon to come in just over 1 kg with gravel-ready toughness and room for 40mm tires.

Braided Carbon Structure & Resin Transfer Molding

Time gave us an in-depth look at the unique way they were going to weave together carbon to make their bikes this past winter. And the new ADHX gravel bike is their first model to take this Braided Carbon Structure (BCS) system off-road.

By radially braiding dry fibers Time has unmatched control of material placement with the tubes of their frames, while also allowing them to introduce unique reinforcement like this new Bio-Based Dyneema, Vectran, more conventional hi-mod carbons, or even Kevlar to address specific loads on a bike.

Time only adds the resin under pressure into the final complete mold (RTM) , after individual tubes are woven over mandrels then assembled together dry into a complete bike. This allows much more precise fiber placement, more layup flexibility, more workable molding time since they are using pre-preg, and ultimately a lighter & more refined resin composition.

This is in many ways similar to how 3T makes the Torno cranks & the new Exploro Italia at their HQ in Italy.

Bio-based Dyneema

We mostly know Dyneema in cycling from fiber spokes, bikepacking bags, ultralight textiles in shoes or even crash-resistant bib shorts. But the ultra-high molecular weight polyethylene (UHMWPE) fiber that claims to be 15x stronger than steel can be woven into textiles for all manner of reinforcements.

Time braids it with carbon to increase the safety of their new ADHX all-road & gravel frame in a crash. Engineered to only incrementally increase the strength of the frame in an impact, the Dyneema fibers remain structurally sound for a much longer period after the carbon fibers fail, keeping the bike from failing in a catastrophic way. Effectively, the Dyneema reinforcement allows the carbon bike to bend more like a steel bike vs. the traditionally more brittle failure mode of conventional carbon bikes.

You won’t actually see the Dyneema in the ADHX, though. Time only weaves it into the inner workings of the ‘BCS sock’ at the junctions of the headtube, downtube & toptubes. There, a 20-25% Dyneema composition helps resist high internal forces in the event of a crash, keeping the bike together and keeping the rider safer.

The bio-based version of Dyneema apparently retains all of the performance characteristics of the original petrochemical UHMWPE, but with a 90% lower carbon footprint than generic high-modulus polyethylene (HMPE) according to its manufacturer. The fibers are synthesized from wood waste from the timber & pulp industry, combined with some conventional fossil fuel-based material to create the ethylene.

It’s not totally fossil-free, but 1 ton of bio-Dyneema has a 5 ton CO2 reduction compared to conventional Dyneema (or 29 tons less than generic HMPE).

Tech details

Time’s new BCS woven carbon ADHX frame – made in Gajary, Slovakia – has a claimed weight 1025g (small, unpainted) with forged carbon dropouts. Officially Time says the all-road / gravel bike has 700c x 38c tire clearance, for a real 40mm measured tire width. Of course, depending on rim width, some 40mm gravel tires might not fit.

The ADHX features fully-internal cable routing through the Deda DCR headset system, which can also work with conventional bars & stems and a cable port in the upper headset cap.

The frame is 1x & 2x compatible with mechanical & electronic drivetrains, and includes a sleek cover over the mounts for the removable front derailleur tab. It features 12mm thru-axles, flat mount disc brakes, BB386 bottom bracket, a replaceable derailleur hanger, and a tidy external alloy clamp for the 27.2mm round seatpost.

Mounting points include a standard pair of cages inside the main triangle, plus a set of direct mounts for a toptube bag.

All-road Geometry

The ADHX’s geometry is more endurance-focused than their similar-looking Alpe d’Huez 21 light road bikes. The all-road feel is meant to be a bit more relaxed & stable with longer wheelbases and 420mm chainstays. But frame Stack & Reach are essentially the same as on the road, with only a slightly slacker (0.5-1°) head angle across the five size range.

TIME ADHX – Pricing, options & availability

Time’s new ADHX gravel all-road bike is available now only as a frameset, but you can pick how you want it to look.

For 3300€ you can pick up a ready-to-paint, primer primed frameset.

Or for 3500€ the EU-made gravel bike comes in four glossy transparent colors that reveal the woven carbon underneath – Amber brown, Cobalt blue, Forest green, or Carbon black.

Then it’s up to you how you spec out your dream bio-Dyneema gravel bike build.

Are carbon gravel bikes strong enough? ›

Carbon fibre is a great material for gravel bike frames due to its lightweight, stiff and highly customisable qualities. A lighter bike means more efficient power transfer. Carbon gravel bikes are the gravel bike of choice for riders wanting a high performance bike for off-road riding.

Are any carbon fiber bikes made in the USA? ›

And this is why Allied is different. Our mission is to make the best carbon fiber bicycles in the world, manufacturing them right here in America.

Do carbon gravel bikes break? ›

However, carbon frames are indeed likely to fail in case of severe and direct impact. If you take a hammer to a carbon frame, you're likely to crack it, whereas a steel or aluminum frame would dent. Still, a damaged carbon frame doesn't have to mean the end of its lifecycle.

Can I use my carbon road bike on gravel? ›

Many riders, especially those who are new to cycling, have a misconception that road bikes should ony be ridden on pavement. But the truth is, road bikes can be safely ridden on all kinds of road surfaces, including cobblestone, dirt, and gravel.

What is the life expectancy of a carbon gravel bike? ›

As far as the longevity of the material is concerned carbon fibre has no measurable degradation over time. This means that a carbon frame is going to be as strong after five or 10 years as it was when it was made.

How easily do carbon bikes break? ›

Carbon fibre bike frames are great to ride, but they are more susceptible to damage than alloy, steel or titanium frames. When working on, moving or storing a carbon bike you need to be careful not to do anything that could lead to preventable damage.

How many years does a carbon fiber bike last? ›

It is said that carbon has a shorter life than aluminum, but if you have regular maintenance, it will last for about 10 years. Carbon is a material widely used in airplanes and is known to be durable. Carbon can sometimes last longer than aluminum and be more cost-effective in the long run.

Do carbon fiber bikes degrade? ›

Carbon bike frames can degrade at a faster clip than say steel or aluminum. This largely depends on how heavy the rider is, how the bike is stored and if it is protected from U.V. (sunshine). It is important to not store carbon in the Sun and some people put sunscreen lotion on the tubes for protection against U.V.

How do I protect my carbon gravel bike? ›

Frame protection for gravel bikes

That's why using gravel bike frame protection stickers is so important. Over time, scratches and chips can accumulate and deteriorate your expensive carbon or titanium frame. The stickers can help prolong the life of your bike and help preserve its value.

What is the best way to transport a carbon bike? ›

Upon arrival at your destination and under intense sunlight, take the carbon bike out of the car to avoid potential damage caused by extreme heat. If there is not enough space inside the car, we recommend using a trailer hitch as the next option, followed by the roof rack.

Can you put a rack on a carbon bike? ›

Some fork mounted bike racks are compatible with carbon bike frames, like the Thule TopRide and FastRide, but older models can exert too much lateral force, causing splintering of carbon forks.

How do you clean a carbon gravel bike? ›

If your gravel bike has become very dirty, we recommend spraying the bike cleaner undiluted on the frame and other parts. Then you can use a washing glove or large soft brush to polish the dirt off your gravel bike. Once clean, rinse your entire gravel bike (including the drivetrain) with water and then dry it.

Should I wrap my gravel bike? ›

The bike wrap keeps your frame and fork looking good, increasing resale value and preventing cable rash from shifting and brake cables rubbing while riding bumpy forest service roads. Gravel bike frame protection lets you ride more and worry less about gravel debris and FSR grime damaging your bike.

Can a gravel bike also be a road bike? ›

Gravel bikes are now so versatile that they offer high levels of performance on-road as well as off-road. That's why many cyclists choose to only own a gravel bike, which they use for both their on-road and off-road needs.

How fragile are carbon bikes? ›

On a carbon bike, the catastrophic failure point is much higher than on an aluminum bike due to the flex qualities of the carbon material. Just as one impact of this nature could break an aluminum frame and not a carbon frame, repeated stresses would also cause an aluminum frame to break sooner.

Are carbon bikes OK for heavy riders? ›

Re: Is a carbon frame worth it for a heavy rider? I have a friend who is carrying a few extra pounds bought a carbon fibre frame and loved it, if it makes you feel good you will ride it, so if you want it yes its worth it regardless of size.

How rough can gravel bikes handle? ›

We don't have wild rock gardens that loosen fillings or 5' drops onto rock slabs, so a bike that can handle those things isn't needed. So my limits would be downhill MTB or MTB trails that have a ton of elevation change along with fast rocky downhill. I can hit some pretty gnarly stuff on my gravel bike.

Are carbon gravel bikes ok for bikepacking? ›

Carbon fibre's pliancy will do a lot of work to minimise any chatter from the surface beneath while still letting you put a lot of power through the cranks. Many of the fastest gravel bikes for racing are made from carbon, but there are plenty of carbon gravel bikes tailored to bikepacking and more technical riding.
