So that's 52mm boost with +3 offset fits a 42T? Presumably 46T will fit with 0mm offset? If I could fit a 44T oval without altering the chainline, that would be ideal.
I'm hoping the new Spark Gravel RC will have generous chainring clearance, which will push the copy cats to do the same.
I had to look this up, so bear with me here. I don't really know a lot about all the different chainlines and offsets.
It's a boost frameset, with a PF30 bottom bracket. This came included with a standard drive-side spacer we used.
Then it's a boost crankset from Ali. The Senicx FM2 with DUB-spindle. So a standard boost crankset I suppose?
The spider is a Xcadey power meter (the 3-bolt SRAM version, gen2). This is the information according to their website:
"The power meter is designed for a boost chainline and can be adjusted to a standard chainline using a 3mm spacer."
We didn't use any extra spacers so the spider is a +3mm offset, and mounted a Deckas 104BCD chainring, this doesn't have any additional offset.
So if I'm right this just equates to boost with a +3mm offset? So you could fit a bigger chainring if you don't have the +3mm offset in the chainring or spider.
This weekend I can take some pictures of the clearance of the chainrings on both bikes.
