When I'm not bicycling, I'm a Linux SysAdmin. I'm on the board of my local bicycle advocacy group.

Bikes are my primary transportation. A 2009 Surly Long Haul Trucker, set up as a commuter and a 2012 Trek Ion CX. I also take the bus, but do not own a car.

comment Child seat (or rack) at the seat post
Welcome to Bicycles! We're really looking for answers with more details. What, exactly, is a "tyke toter"? What differentiates it from other similar things?

comment Rear wheel at edge of dropouts on a Surly Cross Check
Note from Surly's site about the current Cross Check rear dropouts: "Semi-horizontal dropouts give you singlespeed compatibility and wheelbase adjustability. Adjuster screws are included to keep your wheel in the right place for optimal shifting if you go with derailleurs."

comment Long commute (~30km/18.5mi) considerations/logistics
Welcome to Bicycles Stack Exchange! I have to agree with @Mσᶎ, this is too many questions all in one. A few of your questions already have decent answers on the site. Could you please split each question in here off into its own question on the site?

comment Help identify this frame
More pictures would help. A clear close-up of the different parts of the drive-train (front and rear gears, front and rear derailers), of the brakes, of the brake levers, of the shifters, and of the stem. If there's any kind of markings visible on them, also the front of the head tube and the hubs of the wheels.

comment How has biking changed in the past 15 years?
Also: (road): ramps and pins on cogs to improve shifting performance and increase the maximum jump, leading to the compact double (making a double instead of triple a reasonable non-racer option). An increase up to 11 gears in a cassette. Tapered steerer tubes (headset wider on bottom than top)

comment Rim Stickers/Decals
Welcome to Bicycles Stack Exchange! Could you please add a close-up picture of the brakes and of the rim sticker skid marks? It's difficult to see any detail in this picture.

comment Properties with Belt-driven Chains?
Very minor point: sometimes it's the dropout that's split. Either way, I think they avoid reducing rigidity by, basically, adding more material in that area.

comment Are both sides of a Avid rotor the same?
I've never heard of disc brakes on the right side. At first I thought you must have the fork on backwards, but I was able to confirm in their specs and photographic evidence that some roadrats have a right-side front disc brake. More information about their reasoning here: cotic.co.uk/geek/#ROADHOG_discmount

comment Are both sides of a Avid rotor the same?
According to their specifications and this pic of a roadrat from cotic's flickr, there are right-side mounted discs on some roadrats.

comment Extra screw after removing front wheel (plus enclosed hub brakes)
Does this bicycle have a fender? Can you include a picture of the front half of the bike, too?

comment What is the actual cable pull of brake levers?
@mattnz: I don't think that would be the case, since you need to be able to pull the brake cable some standard amount of mm in order to fully activate the brake. There might be extra pull depending on the mounting, grip, etc, but you'd need to have at least the minimum for that standard kind... There's also lever ratio issues (pairing long pull levers with short pull brakes would require very strong hands)

comment Am I too heavy for my Trek 7200 multitrack?
See this answer: bicycles.stackexchange.com/a/9113 -- That bike is rated by Trek for riders up to 300lbs (136kg). If you keep getting flats, there's probably another cause, such as underinflation (flats with two holes near each other) or running over sharp things.

Based on what I've seen, I believe you would make a decent moderator.

comment Shimano Ultegra vs Shimano Sora
I agree that 105 is a great compromise, since it's basically the previous generation of Ultegra with less expensive materials. However, the question is because he's comparing a specific new bike with Sora to a specific used bike with 2011 Ultegra.

comment Badly rusted suspension fork
Welcome to Bicycles! This answer really needs some more details, not just a link to a video. Maybe just describe the technique that's used in the video?

comment What is a thru axle?
@Ӎσᶎ Most of the through axles I've seen were quick-release and didn't involve an allen key. I don't know about you, but it takes me a few minutes to change a flat, so an extra second really wouldn't matter.

comment What is the frame called that fits 700c wheels?
I don't know of a generic term for "bike that fits 700c tires". Most common road bikes (including racing, touring and cyclocross) fit a 700c tire. "29er" mountain bikes also take that size rim. That rim size is also known as "622" after the bead-seat-diameter of the rim and tire. You could always measure the frame. It should be 311mm (12.24in) from center of axle to (roughly) top of brake pad, and should have room from axle to top of fork (and other clearance points) for 350mm (13.78in) of tire radius.
