At some point next year I might get back to some long distance riding so in an idle moment did some WW calculations on Eagle XX1 vs 2×10 for my ‘Fish.
Assuming RF Next SL G4 cranks – 1x for the Eagle, 2x for the 2×10
Eagle XX1 XTR M980
Cassette 360 272
R mech 265 174
R Shifter 124 117
F mech 0 132
F Shifter 0 107
1x SL G4 425 540
Total 1164 1342
Diff -188g
The eagle eyed (ha) will notice no chain. I can’t find an M980 chain weight and anyhow it’s length dependant. It may be that the 2x runs a longer heavier chain and a DT240S XD driver is 10g lighter than Shimano so lets say in the real world the difference is 200g
As I was doing it I also looked at the other groupset weights not including chains or cranks.
Eagle XX1 – 749
Eagle X01 – 754
XX1 11sp – 616
XTR M9000 – 668+10g freehub
XTR 10sp – 563+10g freehub
The conclusions I take from this is I’m not buying Eagle because I can live with 200g and don’t need the ‘benefits’ of 1x on that bike, that XX1 11sp is an amazing balance of range and weight and that if you have the legs for it XTR 1×10 (or some hybrid thereof)isn’t such a bad place to be.
