    SLX brake on DH bike?

    Just bought a used DH bike for a very good deal. All she needs is a front brake. I have the latest SLX's on my hardtail, and I'm wondering if an SLX up front would have enough power. The bike comes with a 203mm shimano rotor in front and there is a saint rear brake (Maybe 2nd gen) on there. Any advice is appreciated.

    Need a good brake for the front. I would not put a 2-piston brake up there on a DH bike or even an enduro bike. Id want a proper 4-piston caliper.

    Either buy a matching Saint, or move the Saint up front and shorten the line. SLX could be enough for the rear. Maybe not. Depends on your weight and how hard you charge.

    Your about a year out of touch with components.

    Newest version slx are either 2 or 4 piston.

    And a DH trail or endure trail can be alot different depending on where it is. Everyone says at my size I should be riding 4 piston, been riding 2 piston for years and never left wanting more, brakes never an issue.

    Tigris is correct, I am referring to the quad piston SLX's. I also only weigh 140lbs.

    How will you be riding this DH bike? (Obviously downhill, but the type of trail really matters). You are light enough that an SLX 4 piston would probably be just fine on park flow trails and cascading steeper trails.

    I ride some trails that are steep AF for a long distance, and the only thing that has worked for me are Saints or Zees with 203mm rotors front and rear. Any lesser brake has overheated, boiled over, and even faded to nothing.

    Ya my trails aren't too steep, mostly I'll be riding mountain creek, thunder mountain, windham, and whiteface. I prefer some good flow trails but I'd like something that can handle some gnarly tech if i feel like it
