this question doesn't make sense, because a "cassette-style hub" has a cassette, not a freewheel. if it's a cassette, surly sells a conversion that allows you to fix a cassette. if it's a freewheel, you can do it by threading on a track cog and a lockring. only problem is the lockring and cog are both threaded the same way, so if you break hard with the pedals there is a risk of the cog coming loose. A proper fixed-gear hub has a smaller, reverse threaded bit where the lockring attaches, solving this problem.
Yes, of course. A stem is a solid object. So, it has a fixed shape and fixed volume.
Usually by removing the old switch and replacing with a new switch.
Of course. Almost anything can be fixed with braces.
A race course; a place for running., A course; particularly, a specified fixed course of study, as in a university.
Depends. If it's a so-called flip-flop hub it will, if it's a fixed-only it won't. Flip-flop hubs have regular freewheel threading on one side, and the special fixed threading the other. But the axle may be too short.
well if you think about it if you freeze it then YES of course
Of course. Ask your vet.
Sounds like the freewheel (the clutch prom). You need a special tool to remove it in order to be able to replace it with a new one you can find the tool at a shop near you most of all have them
No, the composition is variable - excepting of course specific recipes.
of course every body goes there
Get the lights fixed, of course!
Because there is no meaningful method of removing these costs. Interest on any loan is a fix expense. Salaries, which is basically what entitlements are, are also fixed expenses.
