The mods I made to the bike are:

Switched out the saddle to a Brooks B17 ($95)

I already had the headlight - Dinotte 5W LED ($159)

I already had the Cateye computer ($49)

Tail light - Planet Bike Superflash ($22)

I already had the tubus cargo rack for panniers ($105)

I bought the Ortlieb Classic Roller panniers off Craigslist ($45)

The bike came with many road components - you can see the specifications at www.bikes.com. Go to the bottom of the dropdown box and select the Sherpa 30 under the touring models.
