Exclusively for our readers, this 2-Pack of Aluminum Bike Pumps, listed at $29.99, drops from $14.99 to $12.99 at Yugster when you apply promo code BDPUMP at checkout. Plus shipping is free. This works out to be $6.50 per pump, and all other sites are charging at least $9 for one. The pump can be used with either Presta or Schrader valve stems. It comes with a bike frame mounting kit and collapses to 7" in length when not in use. Better yet, there is no sales tax (except WA).
