I need new shifters. My bike is currently full Shimano 105 5510. I can get a set of 5510 shifters for about $115. Or I could get an entire new 5700 group set for around $450. Is the upgrade is worth the extra $335?
I'm leaning towards just sticking with the 5510 until it completely wears out. But as I'm already putting some money in, that extra gear, nicer shifters, external BB all sound nice. Thoughts?
