Changes in Tiagra gearset from '14 to current
 
I recently bought a new bike that came with the Tiagra groupset. I knew it was an older model but I was thinking '16. Turns out it is the 2014 model after doing some research. I got a couple hundred off sticker as it was their last one and I am definitely happy with the bike but I was curious if there are any noticeable changes to Tiagra in that time frame.

Tiagra underwent a major revamp in 2017. Yours is Tiagra 4600 or 4500? Latest is 4700.

Tiagra 4700 started getting delivered on 2015 bikes. The biggest observable difference is the gear cables are fully internal instead of sticking out the sides like 4600. The 4600 crank is 5 bolt and the new one is 4 bolt along with the higher level sets, which is ultimately only an issue if you want to replace the chainrings. Functionally they SAY the brakes are better, but YMMV, and they SAY a long cage mech can get you to 34 gears on the back. Overall the set just has a few more of the bells and whistles of the higher end stuff, at a a lower pricepoint/higher weight. From a cost effectiveness perspective, unless your wheels only have 10-speed hubs, there would be no reason to upgrade to 4700, because if you were considering it at all, 5800 is marginally more expensive, and by most accounts quite a lot better.

Until OP says what he has ... no way to tell him about it.

I believe its 4600. The rd is stamped 4601. The bike is the 2014 Masi CX Comp.

4700 is a step up ... but 4600 works quite well.

4700 benefited a lot from 5700/5800 105, I hear, in terms of its internals, and it has the under-tape cable routing which most people prefer.

On the other hand, 4600 shifts beautifully.
