    970 front derailleur

    I want to change my front derailleur on my 970. I know it is a direct mount but can someone tell me if it is a high or low?

    It's the E type direct mount, depending on the front gearing you're running it would be a E or E2 in Shimano and it would be a low mount DM SRAM.

    It is the stock sram gearing the bike came with. 2 rings up front. Is that low then?

    In SRAM there is a specific S3 DM direct mount FD size for each 2x10 chainring combo (22/36, 24/38, 26/39, 28/42), in Shimano FD's, the E2 is for the large 10 spd chainring in the 38-40T size, the E is for 40-44T large chainrings.

    The SRAM S3 mount is the two hole 22.1mm spacing (E-type). There's no chain drop plate for the SRAM FD, but there are specific Element chain drop plates available for the 2x10 and 3x10 Shimano FD's from Rocky.

    BTW, the high and low really only refer to the clamp type FD. The direct mounts have 3 options, SRAM H0 type DM FD is the single bolt direct mount with the vertical key slot, the S2 is the two bolt 42.7mm spacing (Spesh) and the S3 is the two bolt 22.1mm mount.

    970 front derailleur

    Sounds confusing. I assume I need s3 24/38 bottom pull. Not sure what you meant about chain drop plates.

    Here's the diagrams from the manual, the Shimano FD's have accessory plates to prevent the chain getting jammed between the small ring and the frame. The SRAM FD have a different shape inner plate so they likely aren't necessary

    I just put a FD SH XT M780E triple FD on my rocky. It did not have the plate (#1). So I didn't install it. Do I need it? Does it come with the XT FD, because it wasn't in the box.

    The chain drop plates are a Rocky piece, they would normally come with the frame if it had Shimano FD.

    My frame was Sram. I'll contact RM to see if I can get one from them I guess. Makes sense to have it on there.
