I’m trying to convert an early 90s Technium mountain bike from a 3x7 to a 2x10. Just ran into a roadblock, realizing my rear hub is 130mm and not 135. Can I fit a 10 speed cassette back there? Do I need to custom order a wheel?

Cold set doesn’t seem to be an option. The aluminum main tubes are bonded to the steel rear sections. Should I just muscle it?

Any help or advice is very much appreciated. Thank you thank you
