Kona Coiler 1x Hatchet job

Hey folks

I’m doing a refurb of an old Kona Coiler I have for a friends son to ride (very small budgets to play with)
and I’m thinking about whether to / how to do a 1x10/11 set up on it. It has a shimano Fh m475 hub so no problem there for at least 10 and getting a narrow wide chain ring won’t be an issue either although thinking of leaving the old middle ring (32t) on and just getting a chain guide or using the old mech.

the problem I have is the hanger doesn’t seem to want to fit the more modern spare shimano xt deraillleur I have. Hangers seem to be a bit of a weird science to me. Anyone got any ideas what I need? The old derailleur is an old deore lx circa 2004.

im toying with leaving the 9 speed cassette on but the biggest sprocket on the cassette is a 32 so would make climbing pretty impossible!

    Hanger should fit, seems a pretty normal design.

    Hub wise, an MTB 10/11 spd cassttee will fit that hub, road ones have a wider spacing for 11spd. If on a budget though go with 10spd.

    Something like a Shimano M4120 Long cage which is about £36 should fit, mate that to a Sram or Shimano cassette of your choice an a new chain for the added length.

    Being an MTB though you may get better advice in the MTB section

    As said, your more modern XT mech should fit.

    You could have issues if you're fitting a bigger/wide range cassette that massively exceeds the mech's max low sprocket capacity.

    Might help to see some more pics of the mech in place to get a better idea of the fitting issue?
  • Ok thanks folks and sorry I didn’t realise I was in road riding land. Thought it was generic workshop territory. I’m new here. Still figuring it out!

    I’m tryin to hunt down the derailleur bolt atm so when I do I’ll post a pic of the bad fit. Thanks though will try again.
