comment Is having your hands “on the hoods” of drop handlebars safe for braking?
OTOH, if you're going downhill and not trying to set any speed records it's best to maximize your wind resistance, which means sitting up higher, on the hoods or on the top bar. This reduces the need for braking. (Just sayin')

comment What tools on a multi-tool do I actually need?
@StephenTouset - Yep, though one should carry a couple of "speed links" or whatever you want to call them, and a short piece of chain, if you want to be prepared for chain breaks. You still need the breaker to "clean up" a broken chain and to cut the replacement chain to length.

comment What tools on a multi-tool do I actually need?
Simple answer: You need the tools that fit YOUR bike. In general you want an Allen wrench for every size screw on the bike (anything can come loose mid-ride), plus a basic spoke wrench, and a screwdriver that will fit the adjusting screws on your derailers. A knife blade can be useful, but can be carried separately. Pliers are occasionally useful, but not often enough to be worth it, IMO. (Of course, you also need tire changing tools.)

comment Is having your hands “on the hoods” of drop handlebars safe for braking?
I have a harder time braking from the drops. I have to slide my hands all the way forward and awkwardly onto the curve to reach. It's a motion that can be done in half a second, but on the drops your hands are there already. (Of course a lot depends on the specific geometry of your bar and the position of the levers.)

comment How to calculate bike stand-over height using frameset geometry and wheel radius?
@Kibbee - Yep, with a large picture and the dimension of one tube you should be able to get the standover height pretty accurately, just by figuring proportions. A little iffy on the small pictures you're often given, though.

comment Raleigh AT20 series bottom bracket affects derailleur
Does the BB have adjustable cups on both sides, or just one? If there are adjustable cups on both sides you may have gotten them misadjusted. Also, if this a loose-bearing BB or a cartridge with two adjustable cups you may have installed the axle backwards. Or it may be that you simply do not have the BB cartridge fully seated into the recesses of the cups.

comment Chain Lube Compatibility?
Any decent chain oil should do. You don't need to clean between different oils unless you're switching between a purely synthetic oil (eg, Teflon with no petroleum "vehicle") and a petroleum-based oil. (At your rate of use you should clean your chain every month or so, more often in wet weather or dusty conditions.)

comment Rear derailleur and front shifter are not indexing “together”?
Here is an extensive article on cables, probably more than you wanted to know, and another article on derailer adjustment, probably a better fit for your immediate needs.

comment Rear derailleur and front shifter are not indexing “together”?
Replacing a cable is not rocket science, but it requires some mechanical skill and intuition. It's hard to tell what you did to it (did you physically disconnect the cable?) but anytime the cable is disconnected (or somehow loosened such that it's tension changes) then it needs to be re-adjusted. Small adjustments can be performed with the "barrel adjusters" usually found inline in the cables or where the cable exits the shifter. Larger adjustments require loosening the cable clamp and moving the cable in/out.

comment Vegetable oil to oil a bike?
I think it's OK as an "emergency" chain oil. You should probably remove as much as possible and replace with something else as soon as you can, but it would be OK for a week or two (though maybe not the optimum lubricant).

comment Can a chain-lock be better against cutting than a U-lock?
(In fact, they could make it really "interesting" by enclosing the chain in a gel which would foul a cutoff blade.)

comment Can a chain-lock be better against cutting than a U-lock?
From a practical standpoint you'd need to cut all the way through one side of the link and at least halfway through the other. Cutting only one side would be sufficient if you had something to pry apart the chain, but doing so would be more tedious/time-consuming than cutting the other side (and would risk more damage to the bike). They could make things even more "interesting" by criss-crossing the fabric sleeve with steel wires which would tend to foul the cutting tool, but I'm guessing they didn't do that.

comment FC-M330 replacement
That's a square taper, so you might consider going with a 3rd-party supplier. Unless you plan to replace the entire crankset, in which case it doesn't matter so much.

comment Does frame size inside a particular model affect the ride characteristics of the bike?
@zenbike - Not sure what you mean by that term, but the point is that if the SAME design is used up and down the scale then things will not be right on the ends. And often there are things on the "ends" that can never be fixed -- for the tall guy no wheel significantly larger than the 700c is available, eg (though 24 and 26" wheels are available for shorter people).

comment How can I avoid thigh chafing despite already wearing cycling shorts?
You should clarify where the current "burn" is occurring. If it is the inside of the thighs then your saddle may be too wide, or the height may be wrong. If it's the butt proper or places forward of that then you can either wait to "toughen up" or shave the sensitive area to eliminate the hairs that contribute to the problem.

Use butt butter -- and don't scrimp on it. And no underwear.

comment How to calculate bike stand-over height using frameset geometry and wheel radius?
@Kibbee - I think the actual height of the middle of the top tube above can be calculated from the above if you're also given the dimension between top tube and the top of the seat tube, and between top tube and the top of the headset

Are you looking for the actual standover height, or the conceptual standover height, were it a conventional frame?

comment Evaluate hill gradient
It's some sort of mildly viscous fluid, similar to the stuff in carpenter levels. Survives freezing weather just fine.

comment Evaluate hill gradient
Mine works fairly well. Not on rough pavement, as I said, but otherwise OK.
