GRX 1x crankset on frame with boost spacing?

[Treadly]

Hi BikeRiders

Does anyone know if a 1x GRX crankset will fit on a frame with boost spacing. I’m specifically looking at the crankset for my Cinelli Hobootleg GEO frame. Note, the GEO frame is a 29+ adventure frame. It’s quite different from the other Hobootleg models.

Thanks for your help.

i asked around, unfortunately GRX crankset spindle is too short for this. are the disc brakes post mount?

Thanks for asking. I’ve been told that I need to use MTB cranks. Disc brakes are post-mount. Check

yes, mountain bike crankset is the reasonable choice here; without the flat mount you would not be able to do full GRX setup ... RX812 derailleur would work, yet still no way to work around and have nice GRX setup

Thanks for your help. This must be why the stock setup is SRAM Apex w/ an FSA crank.

Cheers.
