there's another thread going where a few guys got excited 'bout modding a crescent wrench into a low-cost lockring spanner that is just as effective as a high priced version that some want to sell here.
i can only hope the info to save money on cogs (which i consider to be a consumable) that i am about to offer receives as good a reception...
just so y'all are aware, i don't avoid potholes, i do bump curbs, & just a bit of stair & platform jumping, not to mention that i probably ride more miles than 90% of the posters here. i use cheap cogs & my drive train has been silent & trouble free with these...

couple weeks ago i found a relatively inexpensive surly cog in the tooth count i wanted for cheap & despite some recent attacks on surly cogs here, i went for it. so far, 400+mi & it works, my drivetrain is still silent & i could not be happier with it...
so op... i guess the point of my post is...yeah, cogs are different...some are more over-priced than others...
