hmmmm...

Just cleaned my bike... 105 sucks! here we are 4 months into the season, I have replaced a chain and cassette and now the rear derailer is worn out!!! I spend more time trying to keep my bike working than riding it... I don't think 105 was really built with the intention of being used in these conditions with the amount of miles... it would work for an entry level race bike or for the hobbiest, but I am growing more and more skeptical of it each day with what we're using it for... Ultegra would be the best compromise, I used it last year and the year before and it worked great... plus it's not outragously expensive like Dura-Ace or Campy and works equally well... what do I know, I just ride the bike...
