comment Home-made sealed freewheel?
@gcb: my apologies for not noticing that you wanted a multi-speed freewheel. i guess most people with $50 to spend upgraded to a freehub (though those aren't sealed either, oddly enough)

comment Can I use a cyclocross bike for regular road-biking purposes?
Ignore the advice about weight. A good steel frame weighs four or five pounds. A good carbon frame weighs two pounds. A complete bike is 20 pounds. A rider is 150 pounds. So the frame ends up being about 3% of the total weight you have to pedal up the hill. Skip the cheeseburger and you've saved more than the frame ever will.

comment Home-made sealed freewheel?
@gcb: if you have a $15 freewheel, it's probably worth replacing. I ride a $100-ish White Industries freewheel that's sealed and easy to take apart to re-lube if desired. And once it's apart, you only need a tiny amount of oil to keep everything going.

comment Bar end brakes and handlebar swapping
I doubt this will cause your bars to wear more quickly than they already do, although Zinn suggests replacing bars every couple years anyway. I do this and haven't regretted it.

comment My crank fell off, how do I re-attach it?
Should have made that an answer, but don't have enough detail on the problem to really do it well. But basically, if you tighten the thing to the listed spec and it falls off again, the crank is dead and you need another. Whether or not this happens with splined cranks I'm not sure; I had a bike that used one once, but I tightened to the listed spec and everything went wonderfully :)

comment My crank fell off, how do I re-attach it?
The torque you list is for the bottom bracket cup. Once the crank falls off due to lack of tightness, you need a new crank and maybe a new bottom bracket. This is not true of cranks that are kept on the axle with pinch bolts, but you don't seem to have this type. If you keep tightening the crank onto your perhaps-misadjusted bottom bracket, you can eventually split it. If you can risk it, try tightening to the max listed torque on the crank's bolt. My bike says 40Nm, and that's what I tightened it to. (But mine is a JIS crank, not an ISIS/Octalink crank.)
