New Garmin coming out.. .  
EDIT: my link won't paste but its on DC Rainmaker's page.


Speaking of tubular repair. If there is interest, I'll organize a group repair to get cheaper prices. Lt Dan and I were talking about it and we each have a tub that needs fixing. Let me know if you've got tubs you want fixed.
I think I have 3 that need repair

Here's another article that shows you how to get free maps onto your Garmin head units that support mapping:

Is that the new iPhone?

The new Garmin is $$$. And big. Love to see an updated edge. 500 computer....LCD is fine with me
you can orient the new Garmin 1000 horizontally.  Which is great, because it can work as an aerobar extension in that orientation.

Or an airfoil and adjust for the right down-force, just like an F1 car.

I ride enough in unfamiliar areas where being able to glance down at a map while riding to make sure that I'm on track is something that is VERY appealing to me. Yeah, it's a bit on the big side. And of course it sounds like, with a free work-around, you can do the same with the smaller 800 series. But also, racing with such a large computer on your bike seems sketchy. Although, I'm not opposed to throwing things in my jersey pockets for racing.

But, here's a question for you Garmin folks, it seems like every other week I'm reading about these computers going flying off someone's handlebar mid-race. Is the mounting system a real weakness?

Also, with the size of it, we're fast approaching iphone size and that makes me wonder, how far are we away from smart phone apps that can do all the functions that a cycling specific computer does?

p.s. it's all theoretical for me...no way in hell do I have anywhere near the money for that kind of computing power.
@Marc -

1. I think I'm the only one that has the "flying off the handlebars" issue and the initial time was because I crashed at Grant's and broke the tabs off the thing.  Losing it completely at Battenkill was because I didn't really "fix" it so it wasn't as secure as a new one.

2. There are a number of high end phones that are Ant+ equipped and with specific apps do support speed/cadence, heart rate, and power.  I attempted to try this this week before finding out that it is still sort of half baked and gave up due to the wonky UI and poor support.  I bought a replacement Garmin instead.  Maybe in another year or two developers might polish it up and set better integration standards.

3. There are a good handful of mounts available for smartphones in the market now (and probably a dozen more on Kickstarter).  Yet, like you noted, mounting a $500-700 retail, easily damaged, nearly essential part of modern living consumer electronic product mounted where it can easily be cracked/broken doesn't seem ideal...

Also, with the size of it, we're fast approaching iphone size and that makes me wonder, how far are we away from smart phone apps that can do all the functions that a cycling specific computer does?


Or Garmin will start making their computers with phone functionality..

I would hardly call it every other week.  And if the computer is mounted on the stem, behind the bars, rather than in front, it's harder to knock off.  Though the 1/4 turn mount of Garmin might not be as secure as Powertap's quarter-turn mount, which has a stop.

And Powertap is making a hub that's bluetooth-equipped, so you can thus use your phone with it.

But the phone is far more tricky to me--it's "essential" to many folks and as such, I don't know if they want to risk losing it the same way they do a bike computer.  
Warning No formatter is installed for the format not-found
BTW here is an interesting hybrid computer:

http://www.wahoofitness.com/devices/wahoo-rflkt-iphone-powered-bike-computer.html

Basically your phone, safely in your pocket, does all the work through an app and a little "computer" gets mounted to your bike.  The issue with this is the dependence on a phone and it's battery life which, if the gps radio is turned on, is minimal.  Also they don't specify details about the data and what format it is in, if it is proprietary or compatible/convertible to use with other training software and apps, etc.
along these lines, i had posted earlier that i have recently acquired a powertap wheel with bluetooth.  it works very nicely with strava and wahoo iphone apps.  there is also a powertap app for the iphone, which connects easily to the bluetooth wheel.  However, while the strava info easily uploads to the strava site, i have not been successful in getting the powertap app data to upload anywhere. this is actually important because the analysis software that would be nice to use for reviewing the data and planning resides on the desktop computer, (powerAgent), and i havent figured out how to get the data to the desktop.  will let you know if i can sort it out (support for these powertap apps does not seem to exist), but if it doesnt soon,  i may have to consider getting a garmin. 
Call up tech support at powertap. You might have to look on the cycleops site for the tech support phone number. I have interacted with them on several occasions and they have always been rather helpful.
Tubular question...I've been on my Neuvation carbon tubs for a few years now and have always riddern 23mm Vittoria's.....Is there any reason why I could not mount 25 mm Vittoria tubs to my rims?  I train on 25 now and love how the corner and soak up the bumpy bumps.
No reason why not at all. I have 25mm tubs on all my wheels.
Giddy up!
My tubulars started spewing sealant again today before my race. I followed @mugwump's sage advice to the letter. I rode them a little this week and they seemed to hold okay. Not so much after 10 minutes of warming up at Bethel. 

The cut is about 3mm in length. It sealed back up again, but while I don't mind spewing sealant onto unsuspecting wheel suckers during races, riding at 60 psi is less than ideal. Twice now it has started spewing sealant after the original cut was sealed.

I assume the correct move is to throw out this (relatively new) tire and mount a new one. I just wanted to check with the Kissena-collective-crowd source-mega mind before starting the process of cleaning the rim and gluing a new tire. 

Also, assuming I am gluing a new tire, should I get a new tube sewn into the tire casing by the Florida tubular repair guy?

Sorry for your loss.  but you seem on the right track, and yes, do not throw out the tire.  See if it can be salvaged.
what is the lowest pressure I can safely run in a 700x23 Vittoria Corsa tubular ?  I've been running them at 100/95 but would love to run them at 90/85...thoughts? suggestions?
That depends on your weight, riding style and terrain. But mainly weight.

I'm a little confused by your nomenclature: I assume the first number is the rear wheel pressure and the rear number is the front wheel ? If so most people quote them the other way around.

Anyway to answer your question ... Yes I think you should be able to.

In Johnnycake #2, (where it was snowing on the line), I ran 75/80. Those were 25mm, but I am heavier than you.

rear = higher pressure....I will go 85 front 90 rear on sat.  I weight about 168
Question about Quarqs... Just got a Riken last week. I've been breaking it in, but already got a "Power meter battery is low" warning on my Garmin today. Rode for 25 more minutes and it seems like power is accurate and wasn't dropping. Anybody ever get a false warning? How much life might this battery still have if this warning is correct?

Will power meters forever be a pain?
1. A 2032 battery is cheap.  Buy them in 2-, 4-, or 8-packs.  Replace it before you have to worry about it.

2. Only if you want them to be.

^The soft data and the conspicuously placed ad for Conti 4000 tires at the end make me a little suspicious about the brand comparisons in this article.
Vittoria missing...
