Those that do, do you do it for fun or to save cash – and do you also home mechanic your cars too?
I do my own bike servicing, but I dont do it for either of those reasons, essentially it’s just easier to diy than call lbs, negotiate a time to drop it off, load bike into car drive top shop drop it off, wait a week without bike, Pick it back up,pay for it, find out they didn’t tighten something up coirectly etc.
Diy means I have an hour of bike downtime versus a few days at best, it’s my fault if I cock it up (I won’t) and it’s cheaper. Changing bearings is usually easy. Internal cable routing is fine, although through headset routing looks like a massive pain.
I don’t do my cars because they’re invariably miles more difficult/dirty/messy/require tools I don’t have than changing the bearings on a bike,and the second hand car market likes a full service history, although I did used to service my Caterham 7.
