Wow. I have so many pairs of cycling socks, they have their own drawer. And I have the categorized:some are for trainer use, others for winter, summer training or racing.
As for kits, my team had required guys to buy a new kit each year. The design was the same but sponsor logos changed. We are redesigning for this year as the old design is now five years old. And this year we are doubling team dues but providing jerseys for everyone and encouraging everyone to buy the bibs. But we are a nonprofit first and cycling team/race team second.
