Good advice on the maneuvering CDA, as for trail tactics:
Get the group together, be the team leader, tell them to hurry up "we don't have all day"
As soon as group is almost ready fire up your bike, ride like a bat out of hell. They will be caught off guard and will scurry to catch up.
As soon as you start getting tired, pull over, shut off bike.
When the group catches up to you, state "funny noise in the bike, I'm going back to camp, you guys keep going."
Head back to camp at a leisurely pace, park bike, find shade, grab cool beverage and sandwich, enjoy scenery.
When group gets back say the repair was minor and you headed back out, but couldn't find the group.
Profit.
