How often do you get your road bike tuned up?

Question

or after how many miles?

Answer 1

I completely clean and re-oil the chain, gears and derailleurs every 2 weeks or so (approx 300 miles).  If the weather is wet I'll hose the bike off when I get home and spray a bit of oil on.  I adjust the gear and brake settings as needed.  I guess a set of brake blocks will last 3 months but I check them when I clean the bike.  Everything else is done as required.

Answer 2

If it aint broke dont fix it.

I just clean and lubricate the gears every 1000 miles. ( or if its been raining )
