Tiagra vs. 105 Shifters (w/105 RD) what's the difference?

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

Tiagra vs. 105 Shifters (w/105 RD) what's the difference?

I'm still relatively new to the whole road bike thing. I've been looking at a few bikes, and wanted to know if there's a significant difference between Tiagra Shifters and 105 Shifters, especially if both bikes are using a 105 rear derailleur?

I wanted to avoid Sora simply because it looks like it's more difficult to shift while in the drops (doesn't have that trigger thingy that extends along the brake). So i'm looking at bikes with shifters 1 level above Sora, and noticed there wasn't a huge spread between going with Tiagra or 105 shifters, any noticeable advantages to 105?

Im not sure why people say its that hard to shift sora in the drops. Ya, using the paddles would be a bit easier, but I have small hands and my thumb reaches the button without much effort. Also, after a small break in period, my bike shifts butter smooth. Anyways, if I were you I would probably just stick with tiagra unless you find an incredible deal on something 105 equiped. Like you said, if they both have a 105 rear...

I suggest you ride bikes with different component levels and form your own opinion. Ride a Sora bike while you're at it - you may find that it's not as bad as it looks.

The justification for moving between each level of components is almost always the same - shifts a little bit smoother, weighs a little bit less. Will a recreational cyclist really notice the difference? Most likely not...

Buy whichever one will make you want to get out and ride the bike more.

Aren't the Tiagra brake levers of plastic while the 105's are metal?

Bingo! No but seriously, the tiagra's don't have a shiny nickel finish like the 105's. One guy on our team has tiagra and his have lasted the same as mine, and I have ultegra

If you look on shimano's website the shifters are almost the same. And i beleive both levers are aluminium, the 105 just has a clear and painted options, where tiagra only has a (dull) painted option.
As for shifting difference, it's pretty minute, i went from sora levers on my old bike to Ultegra sti on my current bike, and shifting was almost identical. So the difference between shifters is pretty much just looks, and a couple of grams. So bassicly, the 105 just looks a little more "pro" then tiagra.

I've actually been on the look for a set of cheap 105 black sti's, since it's the only shimano group that comes in black.

As someone that has used sora, i can surely say i hated that little thumb button, it's impossible to reach when you're in the drops, without abnormally twisting your arm to get your thumb to reach, so i'd sujjest you avoid them aswell, but it can't hurt to try a bike out that has them, just to reinforce or prove your notion.

If you're on a budget, there's only a couple components on a bike that really "need" to be ultegra or dura-ace to get the performance edge. Namely the cranks, perhaps the deraileurs, and the cassett for weight savings since it's a pretty chucky part. For front chain rings, sti's, and brake calipers, 105 is fine, chains and pedals are kind of a personal preference, but i'm leaning towards a set of dura-ace spd-sl just for the smoother 3-part bearings which i imagine would be alot more solid, and last longer.
