Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Upgrading 2007 shimano 105s to current Ultegra

I have a 2007 Scott CR1 Team with shimano 105s. My shifting isn't as smooth anymore, I always have to shift 2 down then 1 up (and vice versa) to get to some gears. It used to work smoother for 1~2 rides when I have the chains pristinely cleaned and lubed, but now it just does it all the time, even after sending it to the shop for tuning.

I've been itching to upgrade over the past year (I've snagged deals on look keo blade pedals and new wheels). I've been thinking of upgrading my 105 to the current Ultegra 6800 with the thought that the current Ultegras would be much smoother (and more durable even?) than my 9 years-old 105s. I'd welcome any thoughts/comments. Thanks.

Change the cables, housings, and index your gears. You may also need a rear cassette and chainrings. It'll be like butter for less than $100 invested.

Now if you want to upgrade just to upgrade, then go for it.

Shimano's new 11-speed offerings are terrific, so don't hesitate making the jump if that's what you're wanting to do.

That said, have you tried replacing the shift cables and housing? The PTFE coated cables/housing are very nice and might help.

The new 11speed ultegra is really one of the best bang for the buck group.
I installed on a friends Tarmac SL3 this spring and I am very surprise on the entire package.
As long as you have a set of 11speed wheels, it would be a great upgrade.

for your current set up have you check if the shifters are pulling and releasing the cables correctly?

The shop tuned your bike and it still wasn't shifting properly? Did you tell them? If your levers index every time you push the lever then there's nothing wrong with your shifters.

Now if you're just looking for an excuse to buy new stuff then we can understand

Yep, I had all the cables replaced about a year ago

Yeah, had those checked and tuned.

Yeah, it would ride ok for a few rides and very quickly go back to the problem again, I'm just getting tired to bringing it back so many times (plus one time, they broke the pin in the original shifter and had to replace them too)
