I nearly always ride by myself, but joined a group of ~8 people last weekend. I overheard (was let in on the conversation by the rider next to me) that the other riders "don't like your draft". And she said- as a regular member of this group- that she definitely has a ranking of best to worst draft of the other riders.

As a group newbie, 2 thoughts came to mind immediately (actually 3- the first was "you can tell a difference?!) I have a rear rack for commuting, perhaps it is disrupting airflow and that's why the complaints. The second is that I am not holding a good line and wander side to side too much.

Input? Have you noticed different draft off other riders in groups? I'll try to pay more attention if I join this weekend.

Thanks.
