    Shimano Every Time!

    In making my Trek Marlin my own I bought a set of “Chinese “ cranks. In order to change to direct drive chainrings I bought this SLX set from Biketart. Move on one stage and I took a risk and bought a Deore 11-51 sprocket set from, guess who, the risk being that Shimano advise that on the 11speed SLX derailleur the max cassette size should be 11-46 but I can confirm that the 11-51 performs perfectly not even a sign of derailing on backpedaling on the 51 and that on a 135qr chainline

    Virtually every modification on “Trekkie” is with Shimano parts from Biketart and I recommend them unreservedly!

    Bang for buck best you can get

    Not much different from XT and at a bargain price, they come out top in many reviews, strength to weight is pretty much spot on, fitting is an absolute cinch, Burgtec do colourful chainrings if that’s your thing, what’s not to like.

    But sadly I think shimano may have dropped SLX from their lineup so grab top crank arms at a bargain price while they’re still about.

    Shimano quality

    Hard to justify XT just for a few grams when this crank performs as well as it does
