With the Tour de France kicking off Saturday in Düsseldorf, a few German riders are keen to win the 14km time trial, not least among them world time trial champion Tony Martin. We took a look at his rainbow-themed single-ring bike the day before the Tour begins.

Most notable on Martin's bike is his gearing choice. Using a 54t or 56t big ring isn't uncommon for the world's best time trialists, and a 58t isn't unheard of. But those riders will still use a second, smaller ring. Martin has a single 58t ring.
At the 2003 Tour de France, David Millar used a similar set-up: a single chainring with the front derailleur removed for aerodynamic benefit. He dropped his chain during the time trial.
In recent years, however, SRAM has invested heavily in single-ring transmissions, with a clutch rear derailleur that pulls the chain taut and 1x-specific tooth profiles on chainrings.
Tony Martin is using a standard SRAM Red rear derailleur, but has a prototype X-Sync chainring.
Removing the front derailleur has two aerodynamic benefits. One, getting rid of the derailleur itself eliminates its aero drag. But two, by running a huge front chainring, even Tony Martin will often have to use a larger rear cog, which will pull the rear derailleur a bit closer into the bike's center and thus slightly out of the wind, further reducing drag.
Also remarkable on Martin's bike: Ergon grips instead of the standard handlebar tape and the straight-up grip tape Martin has long trusted on his Selle Italia Tri saddle for keeping him anchored when riding out on the nose.
