    Anyone running a direct mount chainring on a SRAM 1400 crank?

    If so, how is the chainline? What chainring are you using?

    Thanks,

    I have a race face direct gxp narrow/wide in 32t. Chainline seems pretty good, though I haven't measured it. What specifically do you want to know?

    I was curious if the chainline with a direct mount is different than using a std chainring and the spider. If it's different, is it more inboard or outboard?

    Thanks,

    If the chainline is different at all, it is very slight. Within a mm or two, I would think. When using a spider, the chainring sits just inboard of the location where the spider mounts to the crank. When using a direct mount chainring, there is some "dish" machined into the sprocket to make up for the offset, putting the teeth in a similar, if not exact position.

    Any idea when the SRAM X-Sync direct mount 28T GXP chainring will be available? I've got the X1 1400 also, with 30T & spider. On the SRAM site it says 26, 28, 36, 38 DM chainrings would be available April 2015. No sign of them yet though on all the big sites (Comp Cyclist, Jenson, etc).
