Anyone know the difference in weight for just the crankarms? My understanding is that XTR loses a lot of weight in the rings, and given I would swap them out for a 2-ring + bash set-up, am thinking that for the cost, the SLX arms look almost as good and was wondering what the weight difference was.

I dont think the SLX are as fast though.

and as stiff.

I don’t think the XTR rings are particularly light are they? Just stiffer and longer lasting than before.

On weight weenies:

SLX triple inc bb 886g
XTR triple inc bb 786g

So that’s 100g saving. For the difference in price, I reckon you could save a lot more than 100g in other areas of your bike.

I’m bored so weighed my spare rings for ya.

Saint 22 19g
XTR 22 21g
Deore 22 39g
XTR 32 42g
Hone 32 43g
Deore 36 91g
XTR 44 82g
Hone 44 85g

XTR m970 inners are particularly cheese like and have a different offset so you can’t use cheap ones. I’m going to bodge it with spacers.

I use normal rings on my M970 and space out the inner – no problem.

How thick are your spacers mudshark?

If you get the SLX double crankset they have steel pedal inserts .

STIFF ? the SLX are stiffer than XTR and shimano actually say they are 100% stiffer than XT .

They are not as light as XT or XTR and if you are into it …. not as bling as XTR .

I have SLX doubles.

Bare no rings, newest style XTR,

XTR r/h crank 333g
XTR l/h crank 206g
XTR bb 93g

Unless your a racer or have a serious weight obsession why bother with XTR unless of course you have a lot of money to spend on shinny kit.

I was going to buy XTR cranks and now I’ve heard that new XTR is on it’s way already.
