Thanks for all of your suggestions. I have taken many of them into account, so here is an update on the store:

per suggestions, we now have a full line of road, mountain, and hybrid cycling shoes that range up to size 50.

I was also able to find MTB body armor and full face helmets in size XXL, which are in the store now too.

And, the biggest suggestion of all was more affordable jerseys, so those are coming soon (6-8 weeks) along with XXL socks.

I guess our next thing is to work on some less expensive big bikes. keep an eye out.

Also, check out the Zinn facebook page. If you are on facebook, become a fan.

Thanks for all of your support,
