Evening all,

Got myself a new frame this week that’s got a 50mm chainline (i.e for a triple chainset).

Would it be okay to fit a double chainset with a 48.8mm chainline so I can go 2×10?

In case you’re wondering the frame is a Santa Cruz Blur TR (retro 26″ build) 😀 Anyone done a 2×10 set up?

Yes, just do it.

As far as I know the chainlines are practically the same, the way its measured is different.

The chainline on a triple is measured from the center of the seattube to the middle ring whereas the chainline on a double is is measured from the center of seat tube to halfway between granny and outer ring (middle ring on a triple)?
