My frame is crappy but there is nothing I can do about that right now. So I have decided to upgrade components in the hopes of getting a better frame down the road. My current setup is a tiagra shifters noname crankset, unkown bottom bracket, 105 front and rear derailleurs, unknown rear cassette, and terko brakes. What should I upgrade?
I scored a sweet deal on an Ultegra rear derailleur but am perplexed as to where I should spend my money next. Between my member rebate, and gift cards and a pricematch to Performance I can get an Ultegra cassette for about $10 out of pocket, but is that a good upgrade? I have seen used Ultegra cranks going for about $50-80 on Ebay and I can pick up a new ultegra bottom bracket for less than that at Performance but I am just not sure what I am going to get the most bang for my buck out of.
I am riding about 60-80 miles a week right now and am training for a triathlon coming up in May. I plan to continue riding and training beyond that. If I can't buy a new bike right now, where do you guys think I should spend my money? Help me, cuz I really don't have the experience to make the best decision here.
