I met Don tonight. My Boardman had front derailleur issues. Don, is what bike mechanics should strive to be. Intelligent, precise, detailed in tending to your bike and very likable. I like the idea of service to your home. Pricing is very reasonable and you get a lot for the value. Why even go to shoddy bike shops with inexperienced mechanics who are clueless when you have the Tiffany's of mobile bike shops called Velo Zoom! Thanks for all your help.
