Q.
asked by: a guest
Will this hub work with a BMX style crank such as a 19mm 48 spline?
A.
anwered by: canteau
It would really depend on your frame, most bikes that would use a BMX crank are designed for 110mm BMX hubs.

asked by: a guest
What cranksets would work with this hub to achieve proper chain line?
A.
anwered by: canteau
This version of the Surly Ultra New Singlespeed Disc Hub is designed for a traditional 49.5mm mountain bike chainline. Most mountain cranks should be compatible, you may need to use chainring spacers depending on the crank/chainring/frame/freewheel combination.

I am looking for a single speed, freewheel flip flop rear hub on which I can use disc brak
A.
anwered by: canteau
You will need to choose to either run disc brakes or 2 freewheels as the disc rotor need to mount to the non-drive side of the hub.
