Well, one week or so seems fine, but it is also up to what kind
you use. Chain wax tends to wear out fast, while others like chain
lube lasts longer. Got a fren who even uses 2T. But if u wan to
extend the lifespan of your chain, not only important for you to
constantly lubricate ur chain, also important that you wash it
clean. So if you are hardworking enough, a normal D.I.D O-ring
chain can actually last you 2 years plus ....
Got a fren who got his bike over 1 1/2 years ago ... he very
meticulous with his chain, until now also no need to pull chain.
