1x shimano crankset, M980 vs M9000
Moderator: Moderator Team
im looking for a nice SHIMANO 1x crankset to lighten my race rig for next year. I plan on switch back and forth between my SRAM SRM powermeter and the 1x SHIMANO crank for racing. I have a little adapter ring to make both fit in the same BB.
My question is, what would you guys do? Wait for the M9000 crankset or pick up a nice M980 crankset? The drawback with the M9000 is I think it will use a proprietary BCD while the M980 uses a 104 BCD. The other drawback is if im stuck with 11spd chainring on the M9000 due to the special BCD it may not work adequatly on my 10spd drivetrain.
What do you think?

Devinci, just out of curiousity, are you getting a narrow/wide ring? If so, do you have a clutch derailleur? As you are probably aware, chances are you will be able to ditch that chainguide and save some grams...this being weightweenies and all! I was iffy about going bare up front myself, but I have slowly been won over, with no dropping issues since going for that combo myself this past spring.

yep I have the XTR clutch derailleur and will be going with a raceface NW 32T ring. Im not sure about going sans-chainguide. I see a lot of guys at races using XX1 with chainguides!!!! Saying their chain droped way too often. The XTR clutch is pretty soft too so im not sure it would be a safe bet, given I am racing a lot, I don't want to come across such a mistake during a race.

I've seen more dropped chains with the RaceFace NW than any other, I really don't think they made their teeth 'big' enough.
I'd recommend a wolf tooth or absolute black. Also, make sure you tighten up the clutch on the XTR rear derailleur - only time I dropped a chain this year (after racing whole canada cup series) was after Nat's on a training ride, and the clutch had loosened up as expected with a lot of use.
I also think full suspension makes a big difference. Most dropped chains I've seen have been people that still race hard tails.

I've found after most of a season it takes a little more than the half turn he mentions, but you don't want it so tight that it won't shift properly.
Nice, with the dual remote lockouts now there's no reason not to be on a dually.
