Sorry about posting on the topic of my shifter issues more than once, but I need to replace some broken 6501 shifters and I'm trying to decide between a pair of 4500s at my lbs for $50 and these that are listed on ebay:
Shimano Ultegra St 6610 Road Bike Shifter Set 9 Speed 2x9 | eBay
They are listed as 6610s, but based on my research, 6600 was 10 speed, and 6610 shifters did not exist.
Do you think they are 6510s?
On the subject should I expect this shifters to fall apart again in a month making me regret not just downgrading to tiagra, or are these the right choice?
