Ok, I'm a complete Newbie... So please don't hate me to much for asking the question in the Title. I've been doing a bit of paved bike trail riding in Southern California area over the last 2 years on my Specialized Sirrus (hybrid). Anywhere from 25 miles to 75 miles per ride. I like the distance so I can "Zen" out, not really a need for speed. I been just riding in my sweats and tennis / running shoes. Yesterday, I finally picked up a 2010 Specialized Tarmac Comp Double Rival (road bike) at a pretty good deal of $1700 new. I'm pretty sure I'll need some riding shorts or undergarment because the saddle on the Tarmac is virtually not there compared to my old trusty Sirrus... But do I really need the fancy pedal and shoes? Or should I? And why? And I'm looking at keeping it under $190 for shoes and pedal. Advice? thanks.
