!Help needed! Derailleur upgrade, Tiagra or 105?
Hi,
I've just got into road cycling and am loving it. I'm running a 2007 Lemond Etape 16 speed, with Tiagra rear derailleur and Sora front, with Sora STI's. However, and accident resulted in my front derailleur being ripped off and the back bent, and they need replacing. I am unsure whether to upgrade both to Tiagra for £40, or both to 105 for an extra £25. I'm looking to get out a lot during the summer, about 100-150km a week, and am looking at the possibility in the future of upgrade my cassette and STI's to either Tiagra or 105. What would you recommend? Any comments welcomed, I'm a tad bit out of my depth!
Thanks,
Rob
