ITA CRX hardened hubs

[tom91ita]

most comments regarding how often to replace are based on the calendar rather than the number of races or weekends. how many races a year are you running?

for those running a limited schedule (1-2 race weekends per year), how frequently would you recommend to replace hubs/bearings?

p.s.

with regards to legality, when we buy replacement anythings, say brake rotors from NAPA, do we ask if they heat-treated according to the OEM specs? any one still buying cryo treated rotors?

if i am buying replacement hubs from someone, as long they meet the dimensional and basic alloy/material requirements (e.g., carbon steel and not an exotic chrome/moly, etc.), i think that should suffice.

if supplier x heat treats to a different hardness or stress relieves in a different temperature profile, that is their manufacturing process and not an issue, afaic.

With an extremely abbreviated schedule like that, I'd feel comfortable running them for 2-3 years. My "once a year" suggestion was based on 6-7 race weekends per year. My $0.02, YMMV, etc.

edit:

This is assuming that the 1-2 race weekends are super long Enduro's and/or that the driver doesn't pound over curbs too badly.
