City of Calgary reps just came by the office.

They let us know they're completing the 12th Ave track in front of the Guardian building within the next couple weeks. They want it to be complete before Stampede.

It will have those parking spaces next to the track that everyone loves.

Thank the lord, how it just ends at the moment is atrocious heading east. You have to either merge into traffic or then turn north and go around the block on the sidewalk to keep going. Most aggravating part of the cycle track for me for sure.

Kind of funny to run a pilot project and then cripple it with all kinds of closures and detours like they have.

I wonder if it's Guardian delays, rather than City planning, that caused it. Either way, it'll be great to see it completed.

Yes, you can stop better and easier in rain / long descents on disc, but I think that's about it. Disks came from the downhill world of mountain biking, and for road racing applications it seems more of a solution looking for a problem than the other way around.
Braking force/energy is ALWAYS directed through the spokes, if it wasn't your bike would not be able to stop, as that is the direct connection between the frame and the road surface.

You nailed it about being better/easier to stop with discs in the rain/mud etc, but saying "That's about it" is kind of missing the point.
No one has problems stopping in good dry weather, so if all you ever ride in is good dry weather then yeah, discs aren't solving any sort of problem.
If you want to ride all the time, having brakes that are reliable in all conditions are a solving a BIG problem.

That's some serious engineering. Still I'd just call it cheating, not a version of "doping"

They call it "mechanical doping," but the name simply doesn't do it justice. Cycling is not a sport celebrated for honesty amongst even its top riders, but following several very high-profile doping cases in recent years, it seems as though the cheats have been trying a different route: hiding motors in their seat posts that help push them to superhuman feats of endurance.

Isn't a bunch of force from a V or caliper brake directed through the brake to the mounts on the fork and seat stays?

Yeah good point dude, I totally spaced and it didn't occur to me that the brakes are attached to the fork/frame.

Guess I should have drawn a free body diagram.

Either way, I still see disk brakes on a road bike as being a pretty nice upgrade.

Edit: The more I think about it the more I think I was kind of right, if not for the wrong reason.
Either way you are stressing the spokes/rim.

You've either got a tortional force on the hub that has to get transfered to the road via the spokes, or you have a a pair of approximately parallel forces on the rim (road/brake surface)
that will stress/deform it, and that's going to be transmitted to the spokes again.

It might be interesting to see what the differnt forces actually look like.

Your rims will also last a lot longer with disc brakes.

The bike shop here in Airdrie posted this video today. A guy buys a $178 (I think?) Huffy Carnage "mountain" bike from Walmart and takes it down Hawleywood at Thunder Mountain in the Berkshires in southern New England.

Hey, if a carbon Roubaix interests you, mine will likely be on sale soon. I'm done road riding. Did that terrifying road that connects OBCR to Hwy1 (543? 563? 564?) . Never been so scared, I'd take that Huffy Carnage with a loose handlebar down A-line before I ride road again.

Minnie: nice find on that vid. When he finished the run with loose handlebars and no brakes, it's true testimony to fridge magnets sticking to his pair. Oh my.

By the time I finished watching that, 2 things were going through my head. One, Hawleywood looks like a fecking blast and I'd love to ride it some day and great googly moogly, I really appreciate and love my Giant.

Nice commute this morning. I haven't been on a bike in three weeks (holidays in Switzerland!) and I thought it would be a grind. All the hikes in the mountains helped more than I thought.

First time I've ridden to work 4 straight days in well over a year.

Kudos to Ivan, who lent me a pump last night as I got a flat on my ride home. Over a dozen people rode right past, he stopped to ask if I needed help.

^ brutal, I always stop to see a another brothr needs help with a mechanical - gotta pay it forward.

I rode all four days as well this week - and I am finally hoping to get the Thunderbolt out on some dirt tonight as I am planning a rip thru fish creek. We are heading away this weekend and I am not taking my bike - boo!!!

I had a flat last year, and though no biggies I have a pump and a tube in my back pack - turns out I left all my repair gear in a stuff sack at home.

tried to fix the flat with aCO2 and a patch with no luck. Needed to be home by a certain time, so I rode about 3 km on a flat rear tire.
