I have a 148mm boost frame. It has a 73mm threaded bb. Would it be possible to use a "conventional" crankset with "boost" rings, or do "boost" rings only fit on a "boost" crankset?
Cheers
SRAM cranksets the boost is in the ring. Shimano it's in the crank. So it depends what your crank is.
Thanks, that has helped a great deal!
Shimano also have several chainlines, not just boost or not boost. There will probably be a max chainring size you can run on your frame for each chainline. It’s all about chainring clearance really… any chainline will work just fine with the boost positioned freehub/cassette, as long as the chainring easily clears the frame.
Jusat becuase you have boost axle spacing, doesnt necessarily mean that you have to use a boost crankset.
Both my bikes are boost spacing, but I'm running non-boost cranks. The non-boost potentially gives you a better chainline. But on some bikes, a non-boost crank might cause the chainring to hit the chainstay (or get too close to it, and contact if it flexes). I run 30t or 32t chainrings so it works fine. Not sure if I'd get away with a 34t though.
I'm running a boost frame with standard chainset, it works fine. Actually both my bikes are the same, I upgraded frames but switched my old drivetrain across
RaceFace cinch chainsets also do the offset bit in the ring.
