      Nice Crankset at a great price! The SLX Groupset has great performance for its price. Shifts as good as my XT cranks, just a tad heavier.

      Comments about Shimano SLX M660-10 Oe Crankset:

      Installation of this crankset dropped almost a pound compared to the entry-level item that came standard on my bike. The price could not be beat. Wish the item had come with a bottom bracket, though...

        These cranks are a great deal here. I use them on two of my bikes, one is the dyna sys 10 speed setup and the other is a Mega 9 9 speed setup. Cranks work great on both bikes. I like how these cranks look too.

          You could not ask for more performance from a crank, and at this price, the deal can not be beat. Simple as that.

            Comments about Shimano SLX M660-10 Oe Crankset:

            Strong stiff and suprisingly light,It is a lot of quality crank for a very small price. The crankset looks good and you can tell it is made well just by looking at it.
            only 40 grams heavier than the XT due to the steel inner chainring. Stiff and strong
