Trust us @kombatcookie , there's no bull advice on here, just real world riding tips.
Only reason you'd need a standard double (52or53/39) set up is if you can really push it at speed and power levels that you would race with or if say entering local TTs ... or perhaps if you live on the fens or something.

So setting up the 105 today was easy.
I had the Sora set up perfect and now I have this 105 set up perfect too. And honestly there is no noticeable difference in the smoothness of rear shifting. Although the shifters do feel a lot more 'sure'.
Everything does look and feel a bit better made than the Sora
There is more adjustability in the brake calipers.
All the cables go underneath the bar tape, which is nice and tidy. Did not know this, now need new bar tape...
The chainset is a thing of beauty! Feels very light.

First impressions though are that it's not worth breaking the bank for over the Sora. The differences seem small upon installation.
I have not ridden it properly yet though.

Sora is 9 speed though?

Yeah, +50% price for one extra gear and a few subtle changes just has me wondering. Still early days though. Not ridden it properly yet. Dead happy with the price I got it though (£269)

A 20 set up is sublime as far as I'm concerned, absolutely love it - you've got to ride it now, that's what it's all about, a rolling terrain set and a hill spinning set ... simple ... settle into it with some proper miles done and you'll feel the results.

I'm slowly building up the bits. Shifters, chainset, bb and front derailleur got. Mix of tiagra and 105 some 2nd hand some new. Slowly coming together before the big build!

Quick q... on yours can you access the whole cassette in each ring without chain rub on front dr? I have it so close, it must be possible.

I think so, definitely with big front to big rear but not really sure about small front to small rear as never go there.
I ride with headphones on most of time locally so can't be sure - only really ever cross chain from big front cog to back, always get off the little cog up front once moving properly.
Majority of riding now done on big ring, I'll jump to small ring if incline looks like it needs it and cadence demands - never really cross it up much at all actually.

Would be worth buying a brand new rear derailleur. Never truly could know a used ones history. Wouldn't want it trashing a rear wheel cos' it had a knock at some point. I did see 105 one for £24 the other day, I'll try find it again. Or wait for next Ribble 10% code. Is £26.99 there atm. Watch them for upping the price though when they release codes. Noticed that recently on some brake calipers I was considering.

Yeah probably will get new although rear derailleur are fairly hardy. It's normallybthe hanger that bends when bike falls over and that causes the problems rather than actual derailleur being bent

Replaced the rear derailleur and the shifting was superb.

I'm planning on changing my Sora triple to a compact double. It will cost the following to swap. Sora £50 Tiagra £90 105 £110 Which would you choose? I have upgraded to 105 since year. A lot better for my Whitney.

Define 'a lot' for us a bit more would you please fella; most analysis I've read says there's little practical difference between 105 and Tiagra, I have ridden 105 older version but not long enough and not back to back so wasn't able to spot any differences as ages apart ... so what have you found?
