Upgrading...I have caught the disease...help
I have had my bike for 28 days. I love it and am completely happy with it. I ride about 75 miles a week and the best part of my day is when I get on the bike. I absolutely love this sport. Problem is, I can't stop thinking about how to make my bike better, even though I am a casual rider.
I have come into some extra money and want to use it on my bike. I can't decide where to spend the money. I know for sure I want to get a new saddle (the stock Bontrager is horrible) and I'm still deciding what to get. I still have around 400-500 dollars after I buy the saddle. My bike has a 105 rear derailleur and a Tiagra front derailleur and I was thinking about upgrading the Tiagra derailleur. Do you think I would notice a performance difference or should the money go elsewhere? Any recommendations? Thanks!
