As my other recent postings have come to a conclusion with my purchase of a Specialized Sirrus Elite, what now? While purchasing my bike I picked up a water bottle holster, the Specialized wireless computer and a helmet. I think I want to grab some bar ends (no clue which ones), some sort of mount to keep the bikes locked in place in the back of my truck (any suggestions?) and a WalkyDog (terribly named product).

What else should I look into picking up to go with my new toy?
