Technical problems can sometimes defeat the most stubborn participants: while they were in third position, the Colle brothers encountered great technical difficulties with their rear wheel since Turfan. They did everything to try to fix it without being able to find the specific parts needed. They still decided to try the crossing of the Gobi Desert. Arriving in the town of Yumen, they finally made the decision to give up, their wheel no longer supported the weight of their tandem. Their engine was also failing. Their bike was dismantled for a shipment to Guangzhou.
