LFGSS Cycling Jerseys... gauging interest on size and numbers

I think you underestimate the costs, or overestimate how much bike shops would contribute. They would have to be contributing a good chunk over what they're likely to get back in terms of sales given that only 100 or so people will own the shirt and we'd need to knock off a huge chunk of the underlying cost to achieve it.

That, and I kinda like it logo free... it would ruin the effect of the design (I can say this, having seen the design).

undoubtedly I do but I thought I'd throw it out there...

and yeah incorporating logos would rely heavily on the design too as you say on more team style jerseys they wouldn't look out of place (like on the leopard trek one posted upthread) but for a more designer'y design they would.
