I've been getting an increasing number of requests from random people for help deciding what bike to buy, whether to get a carbon wheelset, or whether they should use a longer stem. In short, people who want advice but don't want a bike from me.
Folks, this is my living. I enjoy my work but I don't have so much free time that I will happily answer your question about what size Kona to buy. If you live in Salt Lake and swing by with a 6 pack, you can probably pick my brain for half an hour and I won't complain, but if you're not a personal friend or a customer (or at least thinking about being a customer) I can't help you.
That said, I do have more experience fitting and designing mountain bikes than all but a handful of people, so if you really, really want my advice but don't want one of my bikes, you can hire me to do as much fit/design/componentry consulting as you'd like. But it's not free, so don't just email me with random questions and expect a useful response. It's not that I don't want to help you - it's that if I help everyone, I won't have time to ride, build bikes for paying customers, or hang out with my family. I wouldn't come to your workplace and ask you to help me for free - so please, extend me the same courtesy.
