I have a New frame with boost wheels, I’m looking to move my double crank from my older non-boost frame to the new one and run 1x11. Will it work? Does the single chainring need to have spacers for the wider chainline. And any recommendations would be great thanks. If standard chainrings work then I’m thinking hope retainer or a snaggletooth. Cheers
Just try it first. At worst you'd have to buy some 3mm spacers and some longer chainring bolts. Cheaper than new cranks! You might find it's fine without spacers. Uberbike and superstar chainrings are decent if you're looking to spend less.
Could I also mount the chainring on the other side? Where my bash guard mounted on my double cranks?
Well if you told us what frame and cranks you have we may be able to advise better!
You should be ok with double crank, the big ring position on a double is very similar to a boost crank anyway. Couple of things to watch out for though, if it's a shimano crank then you can't run a 32t ring unless the ring has standoffs and threaded holes machined into it as with a standard ring, the chain will foul on the tips of the spider. Also a ring with the standoffs built in will move the ring back to the non-boost position and may foul the frame.
A double chainset with bashguard is basically a triple which differs from a double chainset that can't except a bashguard, I'm assuming your chainset is 6 or 7yo, similar to an slx 665 with bashguard, so will give you about 54mm chainline in outer position, boost adds 3mm either side at the back so 53mm chainline is what you're after so you should be okay with 54mm. Basically your cassette is now 3mm outboard so the chainring should do the same.
