Thoroughly confusing myself now...
[i]For comparison, full on 1x XT m8000 chainset is ~£88 plus ring (£34 -50) plus BB (~£13) = total £135+. [/i]
SLX m670 3x, drop granny and outer ring, £70 all in with BB included (upgrade to NW ring later).
SLX m675 2 x - seems not to be in stock except evans, and poss probs with ring <34T
There also seem to be SLX m672 and m677...
So what is everyone running now? Is the lack of M675 a subtle sign that they are about to bring out a new design?
Don't fancy a zee/saint 1x.
Any advice/opinions gratefully received.
I had the trusty double+bash SLX ones until I realised my messed up ankle meant I needed shorter cranks - so I have some lightly used 175mm ones of them to rehome. M665, that's it. For 1x I'd always want 3x spaced chainrings (double+bash is 3x arrangement).
Don't try to run a ramped middle ring or you'll end up needing a guide as well - which will cost more than and work less well than a narrow wide. Actually I've got a 34t one of those to rehome as well. God, I have so much gear to sell...
I got the slx m675 last month, but as you say no one seems to have them now...Hhmmm. Sorry but I am no help.
Personally I'd prioritise correct chainline over everything else, therefore if you're going to use a ring with built in threads & spacers (30t round or 32t oval) go for the M675. If running 32t round / 34t oval or bigger go for the M670. Also don't forget to factor in the cost of some shorter chainring bolts / shims / outer bash ring if going with the M670.
andy4d - how do you find the chainline on the 2x? what size ring?
I presume the outer mount, but can you fit a 32?
davewalsh - I'm after the best chainline, do great difference in look/price, and weight will be similar once I've binned rings.
I have spare 'short' bolts.
What rings come with builtin threads/spacers?
I am leaning towards the m670 3x, bin the outer and inner ring, should be able to run a 32, and a bash if I fancy later.
I am aware the ramped rings will be a bit jumpy, but it's flat round here and it worked on my last 1x til it got nicked (hence low budget to replace)
any one else before I buy the wrong one?
ordered the M670 3x.
Now waiting, wondering if I could fit a 30 in the middle ring position if 32 is too big...
Does anyone know?
Madeupname Yes you can I've done it no problem also you can run a bash gard as well where the big outer ring is placed .
Middle position on a 3x chainset is the correct position for chainline on 1x.
30T will fit fine as it has clever little integrated threads.
