DC Rainmaker's power meter buyer's guide is out:

Also, I found this interesting....those Zipp's are awesome but too many watts and you'd go into low gravity. How is it faster than last year? More dimples! All about them dimples.

they say they changed the shape of the rims. they also redesigned the hubs. both reduce drag (if you believe Zipp). obviously not much is known yet by anyone other than those at Zipp.

both are somehow rather irksome
everything is based on price and price alone with no mention of historical issues when it comes to reliability. i especially like how he dismisses the more mature products out there (Quarq, SRM, and Pioneer) and also calls the "gold standard" label undeserved.
those pseudo-scientific speed tests are quite misleading. 9% (380 to 345) in savings due to wheels alone at 41kph when wheels usually save ~18W at 30 mph (and more like 13W at 41 kph)? I'm calling BS here

eta: i take back the point in the second one a bit as it could have been incredibly windy, in which case savings at >10degree yaw becomes significant. However, still irresponsible not to include the testing conditions, etc.

Most Powermeter users live in the bubble of the product they own, and he's one of the few people that can critique a product with no bias (keyword is 'can'). He probably takes more value in the new and shiny products, but I do think he was fair with Quarq and Pioneer.

I stopped paying attention to his PM reviews awhile ago.
SRMs may be expensive, but I've had mine for over a year now and have not had to send it in to be repaired once. At this point in my Quarq ownership, I was on my third one. My PowerTap hub also was extremely reliable, lasting a full five years before the torque tube went on me.

My bike's rear shifter ate a cable head yesterday so I finished the second half of the ride on a very tiny, very nice Specialized Tarmac. Even though it didn't fit I could tell that if it did it would feel way better than my current bike, which means it's pretty much inevitable that the n+1 formula will apply sometime this fall.

How do I get my garmin 520 to auto-upload to Garmin Connect after I save the ride?
Currently I have to navigate into the ride (on the 520), find the "Upload Ride" button and click it. Can't it just auto-upload as soon as I save it?
I googled it and got nothing helpful.

I just started doing this with my 510. Sometimes I have to open and close the Garmin Connect app once or twice before it syncs.

There's a setting in the Garmin Connect app, devices / Garmin XXX / device settings / auto upload. Do you have that enabled?

underneath my worn-out s-works toupe saddle (after 25k miles, the "leather" had worn through and was rough/wearing my bibs) was this perfectly good, glossy, smooth, 99g carbon saddle. it took a couple hours of labor and some adhesive remover at the end, but saved me $300.

So I got into a little scrum at the start of my cross race Sunday and lost a spoke in my front wheel. Unfortunately, the whole nipple pulled through the rim. It's a low profile Vision TC24. Can a carbon rim be repaired? Anyone ever have it done? I sent an email to Ruckus Composites in Portland yesterday but have not heard back yet.

so...pretty sure I just realized why i can't get the seatpost on my cross bike to stay put. i recently switched from using the cable stop that's on the frame for the rear brake to one of the problem solver units (Problem Solvers Rear Cable Hanger w/ Angle Adjuster) as the stop on my frame was too close to the wheel to get my brakes adjusted correctly.
but, i think due to the design of that hanger it's preventing the collar from putting sufficient torque on the seatpost.
current plan is to find a collar where the two ends of the circle don't actually touch so that the hanger doesn't interfere. i think the one from the road bike will work, but right now i'm at work and just speculating. alternatively if that doesn't work, i think i can make something work with a salsa post lock

I guess naked carbon is more pro.

if they sold them that way I'd buy them that way. I tried one of those ebay knock offs but the saddle cracked after ~1000 miles. not exactly the same quality.
