I have seen this happen a few times lately and not always with fast pace line groups. The most interesting thing is that your bike goes back six inches when you stand! Who knew?
>> actually you expose more surface to wind resistance.
>> Avoid it: Watch the pack so that you know when riders up front are slowing. Overlaps often happen on corners, when riders scrub speed; anticipate by coasting a bit into the corner. Leave enough room so that if the rider in front of you standsâ€"which pushes his bike back underneath him about 6 inchesâ€"he won't overlap your front wheel.
And at interactions and on rough roads.
