Who make the best carbon bikes in the world
Road and off-road – where does innovation & excellence come as standard
We recently looked at who makes the best carbon road bike in the world. However, for many cyclists, and especially those addicted to N+1, the wider question is: ‘who makes the best carbon bikes in the world – on road and trail? Is the best bike in the world a road bike, a gravel bike or a mountain bike? That’s a far deeper question, and it relies on us speaking with numerous people, such as Guy Kesteven – the tester man – who knows more about mountain bikes than you can shake a stick. Now, in northern English slang, that’s a whole lot of information.
During 2025, Guy tested many incredible mountain bikes, and one of his favourites was the splendidly engineered race machine from Orbea, the Oiz M-Team. Taking a cue from Guy and adding our own thoughts, the Orbea brand has to be up there, as one of the brands making the best carbon bikes in the world – especially for trail riders. In terms of the Orbea Oiz itself, it’s a lightweight, aggressive geometry and nimble handling trail hugger that wants to fly along the tracks. Add to this the quality of the finishing and the components used by Orbea – along with the size of Guy’s grin factor – and you’ve got a competitor for the best mountain bike. Having used Orbea mountain bikes for many years myself, their quality is renowned; and it’s a brand that has been around for many years, with a rich history of developing high-quality and high-performance mountain bikes (and other bikes) since 1847, when the Orbea brothers opened a small workshop in the heart of the Basque country.
Today, they still design and assemble their frames in this area, whilst their frame manufacturing relies on the expertise in the Far East. Their meticulous attention to detail is legendary, and their latest bikes continue to share this adherence to innovation. The Orbea Oiz is simply a bike that looks quite beautiful, and which rides like an unleashed beast, wanting to devour the trails that you test yourself on.
The Road to Gravel
When we talk about the best gravel bike in the world however, other small artisan brands come to mind. Yes, there’s already a pattern emerging here, as these smaller brands tend to focus on the quality, performance and comfort of their bikes, rather than simply feeding the mass market. And unsurprisingly it’s brands such as 3T and TIME who forge ahead in the context of building the best carbon gravel bikes in the world. Breaking down the gravel biking sector in its constituent parts as it continues to evolve – gravel adventure, gravel leisure and gravel race – it’s around gravel adventure that 3T excel, with bikes such as their 3T Exploro Italia leading the way on innovation, quality and performance. However, when we look closely at the growing gravel leisure sector, we see the TIME ADHX45 taking the lead on the road to gravel arena, as probably the best carbon framed gravel leisure bike in the world.
What both these brands share however, isn’t just an adherence to excellence; it’s innovation and the constant desire to keep pushing the boundaries of what is possible in carbon bicycle frame engineering. TIME, based in their European factory near Bratislava have developed and refined the Braided Carbon Structure (BCS) technique of weaving seamless carbon socks that provide the ultimate in lightness and strength, and which are seen by many as being the best carbon bike frames in the world. Utilising internal and external molds to ensure perfect frame composition with their Resin Transfer Molding (RTM), TIME carbon bike frames – on road and gravel – are simply works of engineering art that ride as well as they look.
Gravel adventure requires ultimate engineering
From their own small factory close to the Italian lakes and mountains, 3T have been creating iconic cycling parts and framesets since 1961. Like TIME, their own team of artisans have focused on developing techniques that ensure a 3T carbon frameset is ready for anything. Like the BCS technique, but also different in many ways, 3T use their own technique of Filament Winding (FWT). Instead of sheets of carbon cut in different shapes and applied on a core, filament winding uses a yarn is spun that is spun onto a core to create a carbon shape. By changing the speeds of the winder, you can change the angle of the yarn on the core. This FWT allows to put each strand of fibre exactly where you want it. Having been at the forefront of the gravel adventure rise, 3T continue to make exceptional carbon framesets such as the 3T Extrema Italia at their home in Italy. And so, we have to rightly ask the question: do they make the best carbon bikes in the world?
Well, in terms of gravel adventure – possibly so. However, it’s time to consider the gravel leisure sector, and that’s a whole new ball game.
Riding the road to innovation & excellence
Going back to TIME and their own industry -leading BCS technique, their forte has always been in designing and creating innovative carbon road bike framesets. Are they the ultimate in carbon bikes for the connoisseur – yes, they very likely are in our humble opinion. When it comes to looking at who makes the best carbon bikes in the world, then TIME must be on the list and towards the top. Every aspect of their process has always been geared towards creating carbon bikes that stand head and shoulders above the rest in quality, performance, comfort and responsiveness. When you buy a TIME carbon frameset, you buy into a lifestyle and culture that exudes excellence. They also allow you to decide on what components your bike should have, so that the TIME bike you ride is your own unique bike.
Ultimately, we all want our own dream bike, and TIME make this possible for everyone. And, whilst they don’t make mountain bikes, as Orbea and the skilled designers and engineers from the Basque region of Spain, TIME do continue to innovate. They never stand still in their pursuit of quality and performance. Launching the TIME SCYLON in 2025, it took the brand to even greater levels of carbon engineering, with TIME testing and using new fibres within their BCS technique, to create an even lighter and stronger carbon road bike. And so I guess, and from a personal perspective ultimately; the best carbon bikes in the world are made by TIME in their factory, tucked away beneath the mountains and rolling hills of Slovakia – and all of us should aspire to ride a TIME machine into our own cycling future.
Fundamentally though, if you’re looking for a carbon mountain bike brand that stands tall above the others, then Orbea should most certainly be on your list. And, when it comes to gravel adventure, then using the 3T Extrema Italia is always going to be a good decision. We do however have to narrow down the final point though, and because of their continued adherence to excellence, their innovation and quality of ride, TIME is always going to be a bike to dream about.
Why… well, because we believe that they make the world’s best carbon bikes, with a passion that is reflected in every quite beautiful frameset.
