Thanks nbt and Onzadog.
It sounds like a Shimano freewheel cluster. I can live with that was hoping for louder but I don’t mind a quieter hub on the hardtail I’m building, a Dr Jekyll with 26″ front 24″ rear. Just ordered the 24″ ADS dropouts as the tyre is close very to the chainstay welds but that was handy for truing the wheel.
Need to decide what forks, thinking either Revelation Air U-Turn or Identiti Rebate XL Jump Fork 10mm or 14mm as I have a 14mm axle with a converter to fit a 20mm Pro2.
Might try new pawls and springs an a little less grease as it got old springs and a lot of grease in there at the moment. My Pro 2 has new pawls and springs and just a smear of grease, nice and loud.
