The bikes ridden by professionals are the best in the business, and when one of them is ridden to victory in a Grand Tour it elevates them even further in the esteem of the cycling world.
It's not just the general classification riders either, there's plenty of admiration for Michal Matthews' Giant Propel - a bike that was ridden to victory in the points classification at the Tour de France; and Simon Yates' Scott Addict SL which he rode to victory in the young riders competition in the Tour.
There's only two bikes to speak of in this section as Chris Froome became the first Briton to win both the Tour de France and Vuelta a Espana in the same year, with Dutchman Tom Dumoulin becoming the first rider from the Netherlands to win a Grand Tour at the Giro d'Italia.
Tom Dumoulin's Giant TCR Advanced SL
The Giro d'Italia winning bike belonging to Tom Dumoulin is one of Giant's top of the range machines, retailing at a cool £4,499 which gives you one of the best all-rounders on the market.
The TCR Advanced SL is made from Giant's advanced composite carbon fibre to make it super light on the climbs, but with a compact shape which makes it ideal for technical descents, of which there are plenty in the Giro.
Using Giant's own finishing kit, the bike was ridden by Dumoulin with a mix of Shimano's Dura Ace 9000 and 9100 depending on the day's demands.
Chris Froome's Pinarello Dogma F10
Pinarello have become synonymous with Team Sky, their clean black colour and signature frame design standing out in the peloton.
Chris Froome has ridden Pinarello bikes to all of his Tour de France victories and the F10 is the latest model to have this honour bestowed upon it. Kitted out with Shimano's latest Dura Ace groupset, the unique thing about Froome's bike is the osymmetric chainrings which he uses to increase pedalling efficiency - which ciomplements his high-cadence style.
The bike is all about the aerodymanics, with flat-back downtubes to shield water bottles from having an impact on the aerodynamics and increases the lateral stiffness which makes for faster acceleration when attacking.
Sprinters bikes are usually stiff machines which focus on better power transfer and handling than the lighter machines which may focus on climbing ability. That's not to say they're not light though, as many of these bikes are still from the top range of machines from manufacturers.
Fernando Gaviria's Specialized S-Works Venge
The Italian had a dream debut on his fiorst Giro, finishing the race with fours stage wins and comfortably winning the purple sprinter's jersey.
The Specialized S-Works Venge he rode to victory is one favoured by sprinters and has been used by several of them over the years including Mark Cavendish. Specialized are the bike sponsor of Gaviria's QuickStep team which has set itself up as a stage hunting team with several key sprinters.
The S-Works Venge uses state of the art carbon fibre technology to optimise aerodynamics along with oversized tubing and a tapered head tube, all leading to a stuff frame which has little flex to allow the best power transfer to the road when sprinting for the line.
Michael Matthew's Giant Propel Disc
The first bike with disc brakes to win a sprint competition at the Tour de France, the Giant Propel is an aerodynamic road bike that's designed to be fast, whatever the cost.
The bike uses Giant's AeroSystem shaping technology to improve aerodynamics and the frame is made from their own advanced grade composite, creating a super light bike.
The bike is stiff enough to take the most powerful accelerations without excessive flexing of the frame because of the oversized headtube which creates a stiff front end to help keep the line of the sprint, and the large, wide bottom bracket to ensure flex is kept to a minimum.
Kings of the Mountains
The King of the MOuntains classification is one that favours the best climbers in the peloton, often finding themselves rubbing shoulders with GC contenders.
The climbers are usually very light themselves - Nairo Quintana weighs in at just 58kg - which means the bikes they ride need to be as light as possible to help them fly up the climbs.
Mikel Landa's Pinarello Dogma F10
As Pinarello is the bike sponsor for Team Sky and with Mikel Landa being Froome's main domestiques it is fitting that the Dogma F10 is ridden by the team, and Landa was able to get the team their first grand tour jersey of 2017 with victory in the mountains classification at the Giro d'Italia.
Warren Barguil's Giant TCR Advanced SL
As a potential GC contender and noted climber, Barguil was riding the same bike that Tom Dumoulin won the Giro d'Italia on when he won the polka dot jersey at the Tour de France, the strong all-rounder TCR making light work of the highest peaks in the hands of Barguil.
Davide Villella's Cannondale Supersix Evo
The Cannondale-Drapac rider helped what has beena poor season for the team with victory in the King of the Mountains classification at the Vuelta a Espana. The Spaniard held the lead in the competition from stage 3 where he took it from Nicolas Roche, managing to keep it all the way to Madrid.
The Cannondale Supersix Evo is Cannondale's top all-rounder, benefiting from an integrated design that saves hundreds of grams to make the machine much lighter than many competitors. Everything about this bike is designed to make it lighter and faster, with even lightweight bearings being used in the headset and aerolite spokes in the wheels.
