The National Bicycle Dealers Association of America (NBDA) has a members-based 'retail data capture' program compiled by industry analysts Jay Townley & Associates. In the October digest - available as a PDF below - the stats show that sales of MTB hard-tails are still slowing and that average retail price trends are more negative than positive, with three out of the top six revenue producing bicycle product categories showing on-going negative average retail unit prices. However, P&A sales remain strong.
