proper air pressure

There are a lot of questions out there about how much air a road bike tire should have.

This has been a hot topic among wheel and tire manufacturers and most of the major companies have put a lot of time and money into testing what is really faster. Nearly every test had the same results. Most people were a little surprised about the results. The tests showed that the pressure that had the least amount of rolling resistance was actually around 90 psi. The general rule of thumb up to this point was the higher the pressure, the less resistance you had. Most people simply aired their tires up to whatever the tire was rated to. What the tests showed was that when the tires were aired up to more than 120psi the tire actually bounced on the small bumps that all pavement has. This bouncing caused the tire to lose momentum and it took more effort to keep the tire going at the same speed. When the tire was aired up to 90psi the tire deformed over the bumps and kept the momentum going. This same result also showed up when using 23mm tires versus smaller "faster" tires. The 23mm tires deformed over the bumps and the 19mm tires bounced on the bumps. If you want to know more about these tests, here is one that is pretty good and it shows you how to figure out exactly what your perfect pressure is for you weight and tire size. http://thelazyrando.wordpress.com/tag/bicycle-quarterly/

Sunday Bike Ride Cancelled

Hi everyone! Unfortunately, the shop bike ride will be cancelled tomorrow. The forecast shows that the temperature will be about 26 degrees, but it will feel MUCH colder. If you do decide to go out, there could be ice on the roads so be safe... You might end up looking like this!

Sleep in and hop on the trainer. See you next week!

2010 Resolutions and Goals

If you've made New Year's resolutions to de-clutter, get into shape, or do a triathlon, then let Jack & Adam's help you out:





DE-CLUTTER: Do you have about a million race t-shirts or water bottles cluttering up your closets and cabinets? Instead of tossing them into the trash, toss them into one of our Green Team Bicycle Re-Cycle bins. There are bins for tubes/tires; bike gear such as chain, pedals, and shifters; and one for cycling & running shoes, workout clothes, race t-shirts and re-usable water bottles. You might consider it trash, but someone else might really want that neon yellow volunteer race shirt.

2010 "Year of the Seminar"

This year starting in Feb. Jack & Adam's will be hosting a series of Triathlon and Cycling related clinics. They will start in Feb. and run through Oct. We will be bringing in a special guest for each one. Some of our guests will include professional athletes, bike manufactures, professional coaches, and many more industry experts to help educate. We are rounding out the topics for all of the clinics and would like some feedback on what you would like to know more about. Please feel free to let us know what you are thinking so we can make sure we are really covering what you want to know about.

Thanks The J & A Crew.

I pity the fool, that don't shop local!

There are really only two options here...

1. You can purchase a Go Local Card for ten dollars at our fine bike shop, and get discounts at hundreds of Austin owned and operated businesses.

Or

2. You can pack up your things, Craigslist your cycling equipment and move to Houston... I know that sounds drastic, but now is the time for drastic things. The tipping point is nigh, my friends!

Well, OK. Maybe I'm being the tiniest bit dramatic, but let me say this. My Go Local Card is pretty much the only coupon discount thingy I use. It's easy, which is great because I'm extremely lazy. It's wallet sized, which is great because I carry a wallet. And it saves me money, which is great because I'm cheap.

The card is ten bucks and expires one year from the time of purchase. At Jack and Adam's you save 10% off of all purchases with the exception of bikes. We're talking race wheels, bike shoes, X-labs and all of the other endless bike related accessories. I've recently finished some pretty advanced mathematical calculations and discovered that basically any purchase over $100 will effectively pay for the card. Peruse the rewards section of the Go Local blog and you will find similar discounts all over town. My personal favorite is the free body mapping from ARP Wave Austin. This, of course, is the process of drawing a map of the city all over your body so that when your iPhone breaks you will not be lost.

Below is a sampling of some other Go Local members in an extremely popular format.

Oh yeah, and if you pick one up at our shop be sure to say that Thomas, sent you in. Not because we have a sales contest or anything, simply because Jack and Angie, have been talking trash about their card selling abilities.

I pity the fool, that don't shop local!

Happy New Year

Super mechanic & husband James playing with his "new toy", a Felt R&D cross country mountain bike frameset that he didn't think he was getting. Bet you can guess what his New Year's resolution is now that he has a new bike...RIDE MORE! Next time you are in the J&A neighborhood stop in, say "hey" and check out the new ride.

Happy New Year!!

The shop will be back to regular scheduled hours of operation starting tomorrow. For Store hour information click here.

Happy New Year
