comment How can I tell if my bike has a freewheel or a cassette?
Yeah, A Specialized bike of that age would most likely have a cassette, but as the OP mentioned, it's a "frankenbike" which means many parts have been changed out. So it's probably worth verifying.

comment Why use 54T (or bigger) chainring?
"A bigger chainring provides closer gear ratios." I think this has a lot to do with it. I changed from a 11-32 cassette to a 12-23 cassette (8 speed), and it's amazing how much difference having very fine gear selection helps. Using bigger front cogs makes the difference between individual gears even smaller, allowing the rider to be in a more efficient gear.

comment Benefits of newer racer bikes over older ones?
The Cervelo S5 is a $5000 bike, not a $2000 one (1500 euros). An example of a $2000 bike would be a Trek Madone 3.1 which looks a lot more like an older road bike than it looks like a Cervelo S5. Sure it still has a full carbon frame, but the look and shape is mostly the same.

comment The shifters and brakes are one piece
And they've convinced the roadies that integrating the shifter with the brakes is the only way to go. Not that I'm really opposed to the idea, but it does make it more expensive to replace components, and makes the components more complicated.

comment Broken glass on the bicycle path, what to do?
Try to ride closer to the road side edge of the path if you feel safe doing so. There will be less glass there as the cars will pick some up with their own tires, and you can maneuver quicker towards the other side to avoid the glass. It's much safer to swerve away from the cars than towards them.

comment Is a bigger wheel likely to get fewer flats?
It get on the order of a couple flats a year, and most of them have nothing to do with actual punctures by objects through the tread. It's either misaligned rim tape, bad valve, badly mounted tube (twisted), hitting a rock at high speed, or any number of other things. When I used really cheap tires, I got a lot more flats, but using quality tires, I almost never get an actual puncture.

comment Theoretical question about double drivetrain (both-sides drive)
White Industries makes the DOS ENO Freewheel Which is a freewheel with 2 cogs on it that will fit single speed bikes. It allows you to switch between different gears, although you have to loosen the rear wheel to do so.

comment Going from a 1x8 to 2x10 setup
You may want to examine your frame to ensure it has braze-ons to accomodate the cabling for the front derailleur/shifter.

comment How has biking changed in the past 15 years?
I guess I would only add in belt drives, which although they aren't very common, are available on some mid-upper range commuter bikes.

comment How has biking changed in the past 15 years?
Unless you are talking really high end bikes, very few things have change. Things have changed more in the mountain bike market with disc brakes and suspension, but road bikes haven't changed all that much. Other than integrating the shifters into the brake levers (Shimano's version was introduced in 1990, 24 years ago), I don't think there's been too many significant changes.

comment Chain not fitting chain ring
I wasn't sure what was going on with the back wheel vis-a-vis the cog/cassette. If it has the original 7 speed freewheel/cassette it's definitely easier to just exchange the chaining for a 3/32 one. If however if you plan to do a full single speed conversion, it's probably a good idea to use 1/8 inch drive train components as they will last a little longer.

comment Tyre Rubber Classifications
@andy256 I'd love to have n+1, but I think I'm getting close to s-1.

comment Tyre Rubber Classifications
I'm with @DanielRHicks on this one. When you're spending $6000 on a bike they have to come up with a whole lot of reasons the bike is actually worth that much. If you're spending that much on the bike, you should really be making your own tire decisions based on your riding style, and not have your decision made by the manufacturer/factory. In fact, you should probably have a few different sets of tires to deal with different riding conditions.

comment Is it ok to mix 23 and 25 tyres
No problems that I'm aware of. I use a 32 on the back with a 28 in the front.

comment Does Bike or Rider Weight / Groupset affect cruising speed on the flat
The more you weigh, the more power required to "get to" a certain speed. But once you are travelling at a constant speed, the only thing you have to provide power for is wind resistance and friction (rolling resistance of wheels, bearings and other things). A heavier rider, assuming the same aerodynamic profile and friction forces will actually not require more energy to maintian a constant speed on a flat surface.

comment Would an original Abloy padlock and [toughened] chain make a good bike lock?
@qarma, why don't they make locks out of the same material as the chain?

comment Would an original Abloy padlock and [toughened] chain make a good bike lock?
Safety is all relative, and depends on where you live. At my office, I see plenty of people with cable locks, even though they are known to be easy to cut, and yet still no bikes have been stolen. Some other places you wouldn't be safe leaving your bike unattended no matter which lock you choose.

comment What could be the reason for stem this far away
Perhaps the previous owner was too tall for the frame and was trying to compensate with a longer stem.

comment Are there front looking mirror options?
It would be very disorienting (and probably unsafe) to ride like this, because you would be seeing a mirror image. Also, your field of view would be quite limited, or it would be distorted because you'd . Not only that, correct me if I'm wrong here, but wouldn't the image be vertically flipped?

comment How much does non-ideal frame size matter?
Is it too big or too small? It's often easier to make a small bike bigger than to make a big bike smaller.
