It's much nicer having your front gears change in an almost instant rather than the click click click...
And the rubbing, over shifting, under shifting.
And the faffing getting incompatible parts to work together. Edit* To which you usually can to a degree.

You're changing the subject lol ... I would like to know what you think is the difference between the dimensions of a Sora and a Tiagra front chainset (of the same gearing numbers on the rings) and then explain how he's making the wrong choice with a Tiagra over a Sora, given it's circa Β£50 ... go on, dig yourself a hole !?!

Read my previous few posts, it's in there why 9 and 10 speed are a mismatch.

I'm not going to dig out the tech docs to quote measurements for you... most of the reasons why they are not properly compatible are in the post halfway down page 4.

... but it's nonsense fella, they're the same size!

... or are they lol? I'll pop a challenge up for you: You say buy the Sora, he's bought a Tiagra (I bought my Sora cheap but he's got a Tiagra here for circa 50) ... explain how the Tiagra has any real differences beyond aesthetics and how those differences transfer to real usage. I'd like to understand how it's a bad choice to go Tiagra over the Sora, in a way that a non specialist will actually notice (or for that matter how a specialist will also)? Let's try to avoid 'Emperor's Clothes' assessments if we can, just saying 'it's better see page 4' don't wash here . Nothing personal, I'm finding this issue quite entertaining, prove me to be an idiot by all means please .

I've neither the time or will to explain this to you anymore Rad. If you really care look into it yourself.
But to get you on your way the chainring spacing is slightly narrower on the Tiagra than Sora. You need the matching FD with the right width to guide the chain on the ramps at the right time, with the right amount of throw from the shifters. I'm bored...
OP and the rest, when you run in to sloppy shifting with this mish mash. The Sram PC971 chain has a width that is in-between the 8 speed and 9 speed Shimano chains. If you go 9 spd chain, it won't work too well on the 8spd cassette side of things, and you will find the 8spd chain is too wide for the 9/10spd parts. So the Sram in the middle does work the best. I know because have done all this.
No more replies from me on this topic. If you really need help, PM me, I'll help you out.

IYHO ! ... you've not explained it well at all, it's simply another opinion amongst many - not born by any facts other than your own viewpoint. A shame you take the 'because I say so' stance ... I thought we were going to be enlightened by an epiphany of science and research. If you actually take the time to look at the dims of the front chainsets rather than wibble on about all the other parts, they're no different (from what I can find? - as I say, show me the money on the front chainset dims). So to conclude, please show me the facts on this whole issue to conclude that the Tiagra is wrong over the Sora front chainset (your argument here), from a bonafide source and I'll go with your assumptions / conclusions ... give me science over preaching ! ...and why are we shouting in big blue text now lol ?

I've told you most if the differences between the two. And some of what this means on how the components work. It's not my opinion at all, pretty much fact. You appear to want this to be some sort of comp or fight. But don't seem to understand any of what I type or what it means. Hopefully readers of this have a little more up there and make better choices of fudging components. Hardly moderator behaviour really. I saw the posts you deleted by the way. Tut tut.

Oh and never said either was wrong or right. Just that the sora would of been better but not perfect. Gave plenty of reasons why and differences between them and some of what that means. Blue writing was to make a valuable bit of info stand out amongst the rest of the drivvle. Steering it down the toilet, grow up.

Lol, wind up mate, thought you weren't going to answer? No posts deleted, pretty clear the angry ranting is one sided here, great posts, make me chuckle. You still haven't shown the difference between the Sora or Tiagra cranks.
