Best bang-for-buck upgrade you have made?

Interested in what riders outside my bubble think.

Adding this to my list, thanks.

Depends entirely on the bike and the rider.

Miles tell you more than the year.

I trust a used bike after a good inspection, not a number.

Value is not the same as cheap.

I check pressures before every long ride.

Import rules make this harder than it should be.

Wash it, ride it, repeat.
