Show me you new style SLX cranks, preferably 1x setup
There is a difference between this seasons XT and SLX in both materials and performance. I was never really happy with the way my SLX crankset shifted. Switching to XT made all those niggles go away. The SLX chainrings are pressed out of steel, whereas the XTs are milled out of aluminium. The visual difference is pretty stark, with XT jumping out as higher-end and SLX looking mass produced. The crank arms on the SLX are nicely shaped, but have a printed shading towards the bottom bracket. This fading is achieved with a 70’s comic style dot gradient. To my eyes it makes an otherwise elegant crank arm look ‘budget’. Others may like the effect of course!
One final point. I rode with SLX in the morning before fitting the XT in the afternoon and heading out on the same loop. If you value looks over performance, then go for the SLX. Otherwise, the XT is better in every way. Incidentally I’m running a full SLX groupset. The rear clutch derailleur, brakes and gears are all excellent. The front mech is good but not great. I’d say the general performance (other than the crankset), is in the region of 2006ish XT.Posted 4 years ago
Hmmmm Id only be running it 1x so it reall wouldn’t matter about the ring weights etc
Surely there can’t be that much difference in performance from crank arms?
I’m now running a slx clutch instead of a xt clutch mech (broke!) and I can’t really tell any difference what so everPosted 4 years ago
To be honest having had both XT and SLX doubles on my bikes recently I can offer these opinions:
1, Black XT cranks have a terribly soft anodised finish that rubs off very easliy and leave the cranks looking a bit messy. SLX don’t.
2, There is next to bugger all difference in shifting or weight, and they’re just as stiff as one another too.
Just make sure you buy a tripple crank set as you’ll struggle to get anything smaller than a 34t chainring in the outter position on the double crank as the tabs on the arms protrude and catch the chain on a 32tPosted 4 years agoI_AcheMember
What if you don’t want/need the extra weight of the zee/saint but you still want to use a 32t single ring? Why are they being daft and making it so people can’t do what they want? If I can’t fit the chainring that I want then I will be looking elsewhere for some new cranks.
What exactly is wrong with wanting to put a 32t ring on a set of cranks?Posted 4 years ago
I can’t believe Shimano have been this daft.
Agreed, a major oversight in this day of customisation and single-ring use.
Just found this though where they are using a 30t (albeit with RF cranks) but it does state they use offset tabs in order to remedy potential chain-rub on rings smaller than 34t.Posted 4 years agomtbtomoMember
The SLX triple is sub-£100, the double more like £120 if that makes a difference.
The new double has shaped tabs that don’t look as though they’re intended to have anything fitted to them on the outside face – bash, outer ring or anything. If you want to fit a 32t chainring, then as pointed out the extended shaped tabs might clash with the chain, or at least prevent you getting a chain guide low enough over the chain.
I struggle to get my chain guide low enough on my XT triple run as a single and that’s with a 34T.
The old style SLX double was the one intended to take a bash ring. The new doubles are more trail/xc set up.
I would think the triple is the one you want and definitely if you want to fit a bash ring.Posted 4 years ago
Just file the arms to fit a 32T – it’s easy.
Thought of this but i’m not into diy.
I’ve got the ‘double’ version on my singlespeed. 5g heavier than carbon SL-K set and almost exactly the same weight as XT. Stiff enough for my little legs, anyways.
Does the FSA ring you have offset tabs?
Just make sure you buy a tripple crank set as you’ll struggle to get anything smaller than a 34t chainring in the outter position on the double crank as the tabs on the arms protrude and catch the chain on a 32t
What fat/skinny are you using?Posted 4 years ago
Another way of looking at it is; the double chainsets have a slightly different chain line on the both the inner and outer rings that puts the outer just beyond an normal triple ring middle ring position and the inner just inside it / outside the normal triple granny ring position.
Therefore a triple ring crankset is the best option for achieving the optimal chainline if you’re opting for a single ring set up, that or buy a single ring specific crank set.
AFAIK a 33t will clear the tabs, but only just.
Or get a SRAM crank with a spider that allows you to fit bling rings and such like down to 28t (I think)Posted 4 years ago

If a 30t RF nw works with a 104bcd, which we know it does because of the simple offset tabs, then all they need to do is fit the same tabs to a 32t.
Or use some washers to space it out…
Having said that, I’m sending back my doubles M675 and getting the triples… M670Posted 4 years ago
kayak – i fitted mine last night too, i took the plunge and got some, would be rude not to at that price!
i managed to get some helitape on the most part and it went on a treat, with no bubbling or anything, its not noticeable, god bless the biketart heli tape!
i must say they feel just as stiff as my xt’s and they look IMO much better, if you glance across at them briefly you can mistake them for XTR…..mmmmmmm xtr cranks 🙁Posted 4 years ago
