All-mountain SLX HollowTech II chainset is tough and aggressive yet also lightweight and excellent value.
Your chainset must fit onto your bottom bracket! There are currently four chainset/bottom bracket interfaces that you're likely to come across. If your bottom bracket is made by Shimano and it has splines, then you need an Octalink chainset. If your b/b is NOT made by Shimano and it has splines, it's almost certainly ISIS. There are a very few non-Shimano chainsets with Shimano Octalink interfaces so, to be sure, count the splines - ISIS has 9, Octalink has (surprise, surprise) 8. No matter which brand of b/b you have, if it has a square interface, it will require a traditional square taper chainset. If you have one of the new Hollowtech II systems, you will need to choose the exact chainset that matches your bottom bracket. Most MTB chainsets are now 9-speed compatible but these will work with an 8-speed system.

Magazine reviews for Shimano SLX M660 HollowTech II Triple Chainset
Review from Bikeradar
Shimano have reset the crankset benchmarks and blown away the opposition with both of their tough, top performing sub-£100 SLX options. The hollow forged arms, and reinforced spider and axle create a stiff yet light base structure and shifting is super smooth.
The steel and composite middle ring on the triple chainring setup adds durability without weight and even the steel inner is drilled so it's only 40g heavier than Shimano's £40 more expensive XT crankset.
Even the double chainring version with steel pedal inserts comes in at 1kg and its wide-range 36/22 gearing makes it perfect for rougher trail work. The honeycomb bashguard bounces off big stuff.
Shimano claim the SLX cranks are 100 per cent stronger than XT, and from the abuse they've handled since we've had them, we're firm believers. They feel as stiff as most downhill cranks, and ramps and pins on the rings give slick and quick shifts.
Shimano external bottom brackets are among the longest lasting original fit units and the two-tone anodised arms stay looking great for months, surviving even a winter of daily abuse in the Peak District and regular downhill use on our double.
The only issue is shallow bottom bracket cups if you're using a non-ISCG chain device, but at £100 they're an absolute bargain.
Tough, light, durable, good looking and superb value

Shimano external BB's are the longest lasting original fit units here and the two tone anodised arms stay looking good for months, surviving even a winter of daily abuse in the Peak District and regular DH use on our double. All this performance and longevity for under £100 make them a steal
The best combination of performance, longevity and cost by a mile.
