Upgrade 105 5510 to 5700 ? Is it worth it?

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?

If the rest of your drivetrain is in good condition, I would stay with 9 speed. 10 speed cassettes and chains are much more expensive. Do you have an online source for 105s at that price?

Yes, from Taobao, China's version of Ebay. http://item.taobao.com/item.htm?id=1139106570

Thanks for the suggestion. Supports how I have been thinking (although a part of me wants people to say UPGRADE, UPGRADE. Shiny new parts! Fun!)

I wouldn't upgrade, I don't think that there any advantage except the extra rear cog.

"upgrade" means ultegra, dura-ace, red or force. changing 105/9 to 105/10 is different, but still the same -- it's a horizontal move, maybe diagonal, but not vertical. changing to 10sp is something to do if/when you upgrade.

The expensive bit of moving from 9 to 10 speed is the brifters. So how soon before the Cassette and chain need replacing? If soon then upgrade to 10 speed now on the Brifters chain and cassette. I run 10 speed chains on 8-9 and 10 speed cranksets so they will not be a problem unless you have something wierd.

But then how long will you be keeping the bike? If it is going to be the only one for a few years then get the groupset. You will not put any value on the bike by changing to 10 speed or having nice new shiny parts on it and it may not work any better.

And for me- that extra cog on the 10 speed does work as the gears are closer ratio. Not so much on the 12/27 cassette but on the 12/25 and 23 it does work
