I change when they wear out. It's not often.
Because the grass always appears greener (often not the case however).
I went through a bit of a mad spell for mibbe 3 years there, chasing the next best thing, was a bit daft really.
Ended up with a Bronson V2 that is by far the best all round bike I've ever ridden, tbh it bloody should be the amount it cost, had it for 13 months now, I can see it lasting 5 years easy.
I'll mibbe have a hardtail again one day, but the amount of riding I do, I can't really justify another mtb.
For me it’s usually when something interesting comes along or when I fancy a change. Main bike model year since I got the bug again have been 2004, 2006, 2009, 2014, 2017.
Add to that ever changing retro and a few modern ht’s over the years. Oh, and a CX bike I didn’t use.
I tend to change while the old bike has value left in it too.
