Dutchman Robert Gesink started his 2017 season in Australia, taking eighth in the GC at the Santos Tour Down Under and 11th place at the Cadel Evans Great Ocean Road Race.

Standing 6ft 2in / 1.89m tall, Gesink's Bianchi Oltre XR4 frame is size 59 and is painted in the brand's trademark celeste green. Part of a continued evolution, the Oltre frames are designed around aerodynamics and the XR4 features a recessed fork crown and oversized aero tube shapes.

LottoNL-Jumbo is the only team on the World Tour currently running Pioneer power meters. The system utilises strain gauges on both sides of the cranks and measures separate left and right force direction, recording power at 12 points every revolution or every 30 degrees. Even still, it appears Gesink runs a Garmin computer in lieu of the Pioneer headunit.

Despite the team's close relationship with Shimano, who provide them with kit, shoes and helmets (though Lazer), Gesink is still running the older Shimano Dura-Ace 9070 Di2 transmission, with a 53-39t front 11-28t rear gearing combo.

Claimed to be the stiffest and most aero handlebar and stem combo on the market, Gesink is also running the new Vision Metron 5D integrated bar with the celeste bar tape stopping just short of the tops.

Shimano also provides the rolling stock for the LottoNL-Jumbo team and Gesink opted for the C-50s with 25c Vittoria Corsa tubulars.
