Try this place. I haven't called with a question, but I have used their 'ask a question' function for a rack once. IIRC, they had a response up within 24 hours. http://www.treefortbikes.com/home

Also, quick question- why the desire for a larger pedal? Are you wanting/needing to move your feet out a bit from the crank arms? If so, then maybe pedal extenders will be the ticket.
