    Need help on deciding a crank... Shimano FC-M542 or SLX M660

    Hello,

    I am currently going from an 8spd to a 9spd. I am trying to decide on which crank to get. I only do recreational XC on my bike and nothing else. I am a masher and weigh 180lbs. There are a lot of 1-3" rocks on the trails where I ride and my cranks get chipped up pretty quick from rocks flying off the tires. As such, I dont care about looks. Should I go with a cheap crank like the FC-M542 that I see on Ebay for 80 bucks delivered or spend the extra cash on a SLX M660 which I have found for 144 delivered. I cant tell if the benefit is there.Thank you!

    If you want to go for the cheaper end of the spectrum, why not try the Shimano M410s. These go for around $35 (plus a square bottom bracket). I have used these, STX-RC and Deore and have seen no difference (apart from weight). A friend also used them for a number of years for XC and light jumping and had no problem.

    Have a look here at the non-series cranks for some ideas on what to search for to get the combination of crank and BB that suits you: http://techdocs.shimano.com/techdocs/blevel.jsp;jsessionid=3TWLJkqBZvxc8D2cm1p07RppcXFL YxLcwYZLhG3v9nHMlBhhvR02!-105830854?FOLDER%3C%3Efolder_id=2534374302051856&ASSORTMENT%3C%3East_id=1408474395181679&bmUID=1239706337433

    I thought about that but I am interested in the Hollowtech type of bottom bracket. It also appears that the m410 is 7 and 8 spd specific... I have spent a lot of cash on my bike recently.... More than I probably should have considering the bike is new so I would like to keep the crank level up a little bit to match my components (I dont want to hear crap from my riding buddies that I spent X dollars on a new fork but bought so and so crankset).

    I know what you mean about matching the level of the components. In terms of the 410 cranks being 7 or 8 speed, I have run them with 9 speed cassettes and chains without any problems.

    From my point of view: I currently have the M542 170mm and I planned to replace it by the SLX 170. I honestly don't have any excuse to justify such a waste of money apart from buying its good design and the 50 grs less for my bike. It is just a question of look. The mechanics and the crank performance on both of them is the same. There's no reason to choose the SLX.

    Having a M542, quality is out there

    I haven't tried the M542, but the SLX is very nice. Very stiff and pretty light.

    Get this:
    170mm) http://cgi.ebay.com/Shimano-LX-M582-...item27afd6aea6

    175mm) http://cgi.ebay.com/Shimano-LX-M582-...item2eab78b979

    LX M582. It's the predecessor to the SLX, and a very good crank. Probably 90% as good as SLX, and the price is right.

    I don't like its ugly dark grey color on the arms of the M582. It is pretty light, though (925grs)

    I got a set from that seller, and they aren't too dark. Just barely darker than the current XT cranks.
