Bit tight for cash this month and [url= http://www.singletrackworld.com/forum/topic/play-in-truvativ-crank ]needing to replace my current crankset.[/url]
Have been looking at the Deore M590 chainset.
Is there any difference in the actual crank arms or BB (aside from visually) between Deore, SLX and XT?
There's a 200gram weight difference*, but I think most of this can be accounted for in the two steel chainrings (compared to composite ones on the XT & SLX).
I know in the past the Deore lacked the hollow crank arms, but is this still the case? Can't find any info on the weights/structure of the arms themselves on the 2010 models
Cheers
* yes I'm a tart
I got the M590s from Evans for £50 last week, they have the hollow arms.
First ride on them tonight.
i got deore 590 and they don't have hollow arms....
slx and XT are very similar to one another.
I looked at same options then went for the non series deore with steel pedal inserts and dual ring.
Now that i'm running a chain device on my fun bike i'm sort of glad i went for the cheap strong option
The SLX hollow axle is stronger than deore (thicker walls).
SLX is the one I would go for. The middle steel composite chainring lasts for ages and the HTII bearings are bigger/better sealed than the Deore ones. There is little difference weight wise is XT. In fact the Deore bearings are rubbish ruin an otherwise good value chainset.
I've just run a deore BB and can't tell any difference between than and SLX so far, had a decent life from it. Think I'll get another again. But the crankset itself, I'd say SLX is still the winner, it's not that much more expensive but it's a reasonable amount lighter. XT doesn't make a lot of sense to me.
