As if I just stepped out of 2007 and have honestly not paid any serious attention to it in the intervening 5 years cos I wasn't looking at getting a 'new' new bike until now. (as opposed to a new one which i cobbled together from 2nd hand 9-speed bits)
I'm particularly interested in bash rings (same is before, only on a triple ring crankset?), and if one or other derailleur allows more slapping about that t' other. Am imagining it to be mopre complicated than it is cos I've not experience of it and just spent an hour staring at online stores until I had a headache?
Other things I should be aware of etc.
Thanks muchly.
It's like 9 speed but it goes up to 10.
Good, just me getting myself all in a befuddlism then. cheers.
Works the same as 9 speed. You generally have a bigger range of gears at the back so need less cogs at the front. Actual cog sizes front and back up to you!
So, from my limited and befuddled research (don't set fire to me) bash rings seem a no no, are they out of fashion? do they need a triple chainset (where as they use to involve the sacrifice of a chain ring they now need space for an extra one?)

Bashrings only seem out of fashion to a lot of STW members 🙂 Depending obviously on your riding but for anything All Mountain and gravity orientated I will always recommend one, it's almost more effort to not have one.
As for Triple chainset, I think the main view point will be its overkill these days unless you do 'a lot' of road roading on your mtb bike.
2 x 10 is fast becoming the standard, and many including myself have dropped down to 1 x 10.
Bashrings aren't a no-no, you can use one if you want. Options up front are the same as 9-speed: triple rings, double with bash, double, single with bash, single. Chain device used with a single ring/single with bash, front mech used with all the other options (obviously). Some chain devices aren't compatible with bashrings, which may be a reason people dont use them as much, but that has always been the case.
The other thing you may have to consider are clutch rear derailleurs, which are meant to be quieter and keep the chain more secure. Essentially they just have an extra spring that keeps the mech from bouncing around, but can potentially make shifting a little slower/heavier. The shimano versions have a switch to engage/disengage this spring, so you can choose quicker shifting or less bouncing depending on what you're riding that day. I don't believe the SRAM versions have the same switch.

The switch is only there so you can disengage the clutch/spring when you need to remove the wheel.
Interesting, I'd prefer a bash as I've got used to them and tend to through my BB overstuff now without a care in the world. I haven't though of goin 1 X 10. could be the answer, my 456 is single ring and I never looked back.
So to put a bash on would you need a crankset sold as a triple, so the bash could go on the outside and even if just a single ring it was the right size to go on and sat in the middle so gets a good chainline to each end of the cassette?
Not at all, what I've done with the New Saint single upfront, is buy an E13 LG1+ With Taco:

Fits onto ISCG or can be fitted to bottom brackets.
And by all accounts the actual difference in shift effort is chuff all anyway!
GSuperstar... that looks like it may be the winner!
Thanks to everyone for the info, I feel at least halfway caught up now.
Interested in anyones dual ring choices also...
not decided on new bike yet but likely to build up a meta SX to my own spec from just the frame... tempted to by full bike and have all this sorted for me, but would loose cash swapping fork and brakes by my calculations.
I personally liked the E13 as it doesnt hide to much of the chainset, for instance mine is going on:

However I used to run 2x9 with a full bash, and didnt look bad, I haven't got a proper close up of that:

If you were considering going 2 x 10 I'd have a look at the SLX range, very good for the price!
10 speed is fine but shimano are now only doing wide range MTB cassettes. 11-34 or 11-36 is common. If you ride XC in east anglia like me these wide ratio cassette are not so useful. You can use the CS -6700 11-28 cassette but thats as close ratio as you can go. If you want closer ratio cassette I don't know if they work well with the MTB mechs.
I think my ideal 2x10 would be 40/28T with 11-28T cassette.

You can always use a road cassette on your MTB
I live in the yorkshire dales, too much range is not my usual issue... 😉
2 x 9 used to be an option for "freeride" bikes (remember them?) people realised that they din'tn use the big ring much, so they could replace it with a bash ring to pretect the middle ring they did use from all the gnar they kept freeriding over.
The more recent 2 x 10 (or 9) is more about the increased range of the available cassettes allowing people to ride 2 rings up front with the same overall gear range as their old triple ring set up, reducing the frequency of those oh-so-tricky chainring shifts. The 2 rings moved up in size to complement the cassette range, to 26-38 or 28-40, rather than 22-32-bash.
Being more about xc and more about weight and efficiency (fewer front ring shifts), the bash is generally left off.
Any good?
I follow the needlessness of bash on XC, but I guess i was also forgetting that very few 150mm travel bikes ever come with a bash, but previously they did come with 3 chainrings so bash was easily fitted. I suspect I thought that as well as now putting short stems on as standard bike companies would put a bash on as standard, the flip to that being that most/alot of those bikes never leave a trail centre red so never need it.
The bit that had me thinking tough is that the 'middle' or second ring is now bigger, so a bash is arguably more useful/necassary.
The CS -6700 cassette is a ultegra cassette. You perhaps maybe able to use a closer one one as well but I thave never tried the RD-T780 mech which is the one shimano recomend closer ratio cassettes, with a a really close ratio cassette than an 11-28. It would probably work but shimano say it won't.
