Most Iconic Downhill Bikes of All Time: Five Models Worth Knowing

Introduction

Downhill bikes are the closest thing mountain biking has to a Formula 1 car. They are built around one job: getting a rider from the start gate to the finish line as fast as possible, in a single run. Climbing ability and rider comfort are not part of the brief, and every design decision serves speed, control and survival on steep, rough ground.

What separates the truly iconic models from the rest is longevity. The five bikes below have stayed at the sharp end of downhill racing for years or decades, reinventing themselves as wheel sizes, geometry and suspension thinking moved on. Each one is still relevant enough today to be worth considering.

What Makes a Downhill Bike Great

Geometry comes first, because it is the foundation of everything else. If the geometry is wrong, it does not matter how good the suspension or the components are, the bike simply will not work. Head angle, reach and chainstay length decide whether a bike feels planted at speed or fights the rider through every corner.

Suspension is just as critical. A downhill bike’s rear end has to deliver traction over small bumps and chatter while also absorbing enormous impacts further down the track. When suspension is not working properly, the rider ends up in the bushes rather than on the podium.

Frame stiffness shapes the character of a bike as much as its numbers do. A frame that is too stiff can be hard to ride, refusing to track corners and terrain as easily as it should, and it can beat a rider up over a long, rough track. Stiffness is a balance rather than a straight win.

Durability and serviceability round out the picture. A frame that fails halfway down a race track is worthless, and for privateers in particular a bike has to be easy to work on. If a part is proprietary and cannot be sourced on a race weekend, the weekend is over.

GT Fury

The Fury arrived in its original form around 2009 as a carbon frame with swooping lines and a futuristic look. Its geometry was conservative for the time, especially compared with the very slack, very long downhill bikes that were starting to appear, and it was a compact machine.

It proved itself quickly. Mark Beaumont won at Val di Sole, one of the toughest and most iconic tracks on the circuit, on the Fury. That result came before the biggest chapter in the bike’s story.

When the Atherton family signed with GT, the Fury was overhauled to the point where little remained beyond the name and the suspension system. That version was extremely stiff, which suited powerful, aggressive riders but could be unforgiving and tiring over long tracks, and it demanded to be muscled rather than guided.

In 2018 GT changed direction entirely, moving to a different suspension layout, returning to carbon fibre, dropping the I-Drive system and stepping up to larger wheels, first 27.5 inches and later 29 inches. For 2023 the design has evolved again with a split seat tube and a rocker tucked inside it. Feedback from riders has been positive, and the platform looks to be moving in the right direction.

Giant Glory

The Glory was introduced in 2006 and borrowed its Maestro suspension system from the Trance, Reign and Faith models that had come a couple of years earlier. It was a fast, capable bike, but it had one well known weak point: because of the amount of rotation in the linkage, it could destroy the DU bushes inside the shock, sometimes within a single day of riding in the Alps.

The bike was revamped in 2010, and the following year it became part of one of the most memorable moments in the sport’s history when Danny Hart won the world championships on it. Giant then updated the Glory again in 2015 with 27.5-inch wheels, followed later by a mixed wheel size version.

The latest Glory takes its paint from the classic 1998 Giant ATX 1, a design that has become known as the Legends paint job. More importantly, it is thoroughly up to date underneath: adjustable reach through headset cups, adjustable chainstay length through chips, and the ability to run either wheel size.

Trek Session

The Session started life as the Session 7 in 2005 before becoming the Session 10 in 2006, a high pivot design with an idler that carried over from the earlier Diesel. The Session 88 followed in 2009 and looked much closer to the bike that is still in the range today. It was the first bike to use the Active Braking Pivot, and it stood out for being exceptionally light for its time at around 34 to 36 pounds, at a price that made it a remarkable bargain.

The racing record is long. Tracy Moseley won a stack of World Cup races on the Session, including the world championships in 2010. Aaron Gwin dominated the field in 2011 on the full carbon 9.9 version, and Rachel Atherton went unbeaten through 2016 on the same platform.

The suspension layout still follows the original Session 88 closely, with one significant change: a return to a high pivot with an idler wheel. The bike has earned a reputation for simply working, and it is telling that professional riders have bought Sessions in the off-season and used them as a development reference for their own race bikes.

Specialized Demo

The Demo first appeared around 2003 with a twin seat stay design, where the inner rear triangle activated the shock in an attempt to isolate pedalling and suspension forces. It looked like nothing else on the market, though it was a heavy machine and was closer to a freeride and park bike than a dedicated race weapon.

Over time it became slacker and more refined, and the Demo 8 arrived alongside a roster that included Sam Hill, Brendan Fairclough and Troy Brosnan. When Sam Hill and Brendan Fairclough moved on, Troy Brosnan stayed and Aaron Gwin joined, and the next generation took a very different approach: an asymmetrical frame with a concentric pivot at the bottom bracket, replacing the complicated double seat stay layout.

That redesign clearly worked. Aaron Gwin won nine World Cups between 2015 and 2018 and took the overall title three times on the Demo. In 2016 Loïc Bruni joined the team, and the 29-inch version followed, even though the team’s riders had wanted to keep a smaller rear wheel. A newer prototype has since been raced, and while the details are not yet fully known, the direction of travel looks interesting.

Santa Cruz V10

The V10 is the longest running name on this list, with eight iterations since the first bike appeared in 2002, more than two decades ago. The name refers to the original travel figure of 10 inches, or 255 millimetres. The first version used a brake arm to isolate braking forces and keep the suspension active under braking, a feature that was dropped for the Mark II.

That Mark II is the bike Steve Peat was riding when he won his third overall World Cup title in 2006. The Mark III followed, and Greg Minnaar joined the programme and won a huge number of races on it, while Steve Peat took the world championships in Canberra in 2009. In 2011 the Mark IV arrived as a full carbon frame with adjustable travel between 8 and 10 inches, and the V10.5 that came next ran 27.5-inch wheels with 8 inches of travel.

Santa Cruz took the World Cup overall in 2014, with the rider starting the season on a 26-inch bike and switching mid-season to 27.5-inch wheels. Then, at the first race of 2017 in Lourdes, France, Santa Cruz turned up with 29-inch wheels, a move that caused plenty of discussion in the pits and prompted other teams to follow. Greg Minnaar won the 2021 Val di Sole world championship, his fourth world title, on the Mark 7 frame that is available today. A Mark 8 frame has since been spotted and looks close to production ready, though full details have not been confirmed.

How to Choose Between These Five Downhill Bikes

All five of these bikes have genuine racing pedigree, so the decision is less about which one is fastest and more about which one suits your riding, your budget and your willingness to maintain a long-travel bike. The generation matters enormously: a 2009 bike and a current bike may share a name while sharing almost nothing else.

Wheel size is the first thing to pin down. The move from 26 to 27.5 to 29 inches, and the mixed wheel setups that followed, changed how these bikes ride. A model with adjustable geometry, such as the latest Glory, gives you more room to experiment, while earlier generations lock you into their original configuration.

Serviceability is worth as much thought as performance. Linkage and shock wear parts, proprietary hardware and the availability of spares will decide whether a race weekend goes smoothly. If a bike uses parts that are hard to source, that is a real cost over time, particularly for riders maintaining their own equipment.

Conclusion

The GT Fury, Giant Glory, Trek Session, Specialized Demo and Santa Cruz V10 have all earned their place through results and through the ability to keep evolving. Each has a distinct character: the Fury is stiff and demanding, the Glory is the long-running all-rounder with an adjustable modern frame, the Session is the lightweight benchmark with a high pivot and idler, the Demo is the distinctive asymmetric race machine, and the V10 is the eight-generation veteran that started the 29-inch conversation in downhill.

Pick the generation that matches your riding and your budget, check that parts and service support are realistic, and any one of these five will give you a downhill bike with real history behind it.
