    XX1 Cranks on Stumpy FSR - Chain tensioner used?

    I'm going to convert to 1x10 on my 13 Stumpy FSR Comp very soon. I plan on upgrading to the XX1 crankset and leave the rest of the drivetrain alone. My RD is SRAM X9 Type 2.

    For those that are running XX1, are you still using the stock chainstay guard/tensioner?

    The XX1 chainrings are supposed to prevent drops, but I wouldn't mind keeping the tensioner as long as it doesn't cause problems. The square-ish shape of the seat tube rules out most chain guides.

    Would love to see some pics of XX1 upgrades that others have done.

    Planning the same thing at some point, but I'd ditch the dangler simply for more efficiency since it just drags on the chain and makes noise while pedaling. The stumpy has IS05 tabs so the chain guide options are endless. Or you could use an e-13 xc direct mount.

    No chain tension here. No need for one. Ive rode some incredibly rough downhill trails and have had zero chain drop.

    I do run an MRP AMG, but only for the taco bash.
