World cyclocross champion Marianne Vos’ Giant TCX DiscRobin Wilmott/Future Publishing
Without a frame size small enough to facilitate Vos’s low riding position, she uses this negative-rise stemRobin Wilmott/Future Publishing
Vos had three TCX Disc bikes and several with cantilever brakes as back up for the worldsRobin Wilmott/Future Publishing
Vos has fully embraced disc brakes, running Shimano’s Di2 R785 hydraulic systemRobin Wilmott/Future Publishing
Another look at that stem, which is 85mm long, and a stated -30 degreesRobin Wilmott/Future Publishing
The clean cantilever-free fork, and some of Dugast’s finest Typhoon tubulars. Shortly after we took these, Marianne had all of her bikes swapped over to Dugast Rhinos for the raceRobin Wilmott/Future Publishing

This version of the TCX still uses conventional quick release skewers, unlike one of the consumer models which features a front thru axleRobin Wilmott/Future Publishing
The Shimano CX75 disc hubs. Note the forward facing dropoutRobin Wilmott/Future Publishing
The unused right side cable entry is filled in to keep the elements outRobin Wilmott/Future Publishing
The Dura-Ace crankset is fitted with Rotor’s oval Q rings in Vos’s favoured 38/46t combinationRobin Wilmott/Future Publishing
Vos uses 172.5mm cranks for a little extra leverageRobin Wilmott/Future Publishing
Shimano’s M980 pedals appear to have been disassembled and sanded smooth on some surfacesRobin Wilmott/Future Publishing
The effect is more pronounced on the other sideRobin Wilmott/Future Publishing
Demonstrating the difference between the high and low points of the Q rings, this is the point where the chainring is furthest from the front mech…Robin Wilmott/Future Publishing
…and here it is at its highest point. On paper, introducing more possible means of unshipping a chain for cyclocross racing seems unwise, but it clearly worksRobin Wilmott/Future Publishing
The bottom bracket area is suitably vast, utilising the shell’s full 90mm widthRobin Wilmott/Future Publishing
The rear hub’s largely conventional looks, with 28 J-bend spokesRobin Wilmott/Future Publishing
Neat mounting for the rear hydraulic caliper and dropout. Like her compatriot, Lars Van Der Haar, Vos uses 140mm disc rotors front and rearRobin Wilmott/Future Publishing

The bridgeless seatstays offer plenty of clearance and nowhere for mud to snagRobin Wilmott/Future Publishing
Even with 33mm Dugasts, there’s ample space behind the bottom bracket shell, and the wide shell sets the chain stays well apart for excellent muck sheddingRobin Wilmott/Future Publishing
The fork crown too has masses of roomRobin Wilmott/Future Publishing
We’ve seen these Shimano 35mm 28-hole carbon tubular rims before, but they still have no name and they’re still a mysteryRobin Wilmott/Future Publishing
The manganese-railed Fizik Arione is at least black for practicalityRobin Wilmott/Future Publishing
