    I have a SLX triple

    how easy is it to make it a 1×9 setup?

    I’d like a nice simple setup – would it be best to buy a single spider for the crank and a chain catcher?

    then check if the chain needs any links removing.

    Very easy.

    Just take off the big and small ring. Replace the middle ring if you want a different size. Fit a chain guide. You should be able to remove a few links from the chain too.

    Worth considering getting one of the new NW chainrings and a clutch mech and not bothering with a chain guide (with a new mech probably about the same price as a decent guide.) I’ve been very impressed with mine.

    You will also nee single chainring bolts to replace the ones you will have on currently

    Clutch mech not an option with 1×9, if you’re buying a different ring I’d get a narrow/wide one anyway, may as well, and pair it with a top guide.

    unless you do the simple spacer mod of course (and run a Shimano mech with a 9sp Sram shifter)

    roughly how much weight will be saved going 1×9 (with chain catcher)

    can anyone guess how much weight this would save?

    I’m running a Works Components Fat Wide ring on a 9 speed non-clutch mech drivetrain, no chain device and have had no issues with losing the chain.

    so you lose weight of shifter, cable, 2 chainrings, one set of chainring bolts and the weight in the difference in length on the shorter ones you use for the new ‘ring. Chain can be a little shorter too.

    150-250g ish.

    Looks good!

    I do worry about the chain on the lowest & highest cogs – he chain will be at an extreme angle…doesn’t this destroy the drivetrain?
