I recommend things I have experience with or think are good products/value, not just to sell stuff.

For such a small shop, RG does a good amount of business. While we do add new stuff to the site from time to time, there's no real need to try to sell everything under the sun. Besides, there are other places out there - like Velomine and Ben's Cycle - who have decent prices (VM's wheelset prices blow my mind), treat their customers well and are generally awesome to deal with. None of us are getting rich selling bike parts and at the end of the day, we all need to eat.
