I'm looking into options for a 1x10 AM setup with a 32t chainring. The rear mech will be a clutch type (SLX Shadow Plus most likely), so no need for a full chain device, just the top "cage" type, but I'd also like a bashguard. So looks like the possible options are:
1: Full chain device (eg. e13 SRS+, e13 LG1+, MRP G2) with the bottom device removed (cut/filed off if necessary). The clutch rear mech negates the need for the lower part and removing it will keep things quieter and with less resistance.
2: Top-only seatpost-mount device (eg. e13 XCX, MRP 1x) plus ISCG-mount bashguard (MRP XCG is the only one I've seen).
3: Top-only device (XCX or 1x) plus full bash ring - not sure if these are compatible.
