Hey, be careful of those split tails!I just discovered a reason not to face your bike rearward on a roofrack, especially if you have a split-tail saddle. And another reason tofile the Nader hooks off of a road fork besides just the convenience ofgetting the wheel in and out!
I was driving into my driveway with a bike on my roof as I have doneproblem-free for 15 years here. It’s a long gravel driveway lined withbig trees, and while leafy branches droop down, I keep the large branchescut back so no big ones cross the driveway less than 10 feet up. Both ofmy garages are full of bikes, so cars do not use them. All in all, thereshould be no danger or wrecking a bike that’s on the car roof, right?Wrong!I had my almost-new magnesium bike on the car roof, facing backwards.As I came into the end of the long, level driveway with a good head ofsteam, the split in the back of my Selle San Marco Rever saddle grabbeda little cluster of leaves at the end of a drooping branch. The saddlehung onto the leaves like a claw hammer onto a nail head and apparentlyflexed the whole branch system the little cluster was on the end of untilit could not flex any further, at which point the tree sprung back, yankingmy bike and its roof-rack tray right off of the roof and dumping them onthe gravel behind the car.
Fortunately, I had filed the Nader hooks off of the fork ends so thebike would come off of the rack. Otherwise, this little mishap could havedestroyed both my bike and my car roof. It did total the fork and the leftCampagnolo Ergo Power carbon lever, though. It also mangled my roof racktray, as you can see in the photo.
One fork dropout came cleanly out of the rack’s fork mount, but theother one got bent on the way out. True Temper does claim that it can gluenew fork ends back into its carbon forks, so I may try this.The lever body of the Ergo Power was crushed, but one of the beautiesof Ergo Power is that every part is obtainable and replaceable. And fortunately,I have just the received the new part from Quality Bicycle Products. Evenmore fortunately, I have written instructions for overhauling these leversin both Zinnand the Art of Road Bike Maintenance and in Zinn’sCycling Primer: Maintenance Tips and Skill Building for Cyclists.I sawed the remaining straight sections of the long rack tray into acouple of short ones, so that’s no biggie. Anyway, be careful of havingyour bike facing backward on your car roof if you have a split-tail saddleon it!Try for a carbon Serotta for a great cause!
Continuing in this free-form format a bit, I wanted to also let youknow about your last chance to win a free Serotta.On August 19-21, my wife and I attended the second annual SunflowerRevolution fund-raising event for the DavisPhinney Foundation for Parkinson’s Disease research. It was a greatevent and included a Friday night silent auction followed by a live auctionwith a gala dinner. Saturday was free-form, with a nice group ride anda Cincinnati Reds game, and Sunday was the organized fundraiser ride. Wewere amazed at what nice riding there is around Cincinnati.One of the people I rode with and attended the ball game with was thewinner of the Serotta Ottrott from last year’s event. He was so excitedabout his custom titanium and carbon bike that cost him a single raffleticket, that I wanted to make sure you have the opportunity this year forthe latest Serotta.I talked with Ben Serotta at the Reds game about it, and he explainedhow they make this superlight carbon frame while maintaining the customfit he is known for. The Reynolds Composite proprietary carbon tubes arebonded into carbon lugs, which Serotta not only stocks in numerous angles,but are extremely thick and use short-fiber, high-pressure carbon moldingtechnology (Campagnolo cranks use this type of system), which allows themto be machined to precise angles and tube fits without decreasing theirstrength.Anyway, the drawing for the bike will be at Interbike next week, soyou can still get a ticket. Here is what Connie Carpenter (Phinney’s wifeand 1984 Olympic road race gold medalist) has to say about it:Davis Phinney Foundation Announces Last Call for Raffle TicketPurchase
CINCINNATI, Ohio (September, 2005) – The DavisPhinney Foundation is in the final days to purchase a raffleticket for a chance to win the ultimate dream bike.

The Davis Phinney Foundationis dedicated to supporting research aimed at understanding, preventing,and treating Parkinson’s disease. The Foundation also seeks to find waysto improve the lives of individuals challenged by the disease. “The DavisPhinney Foundation is more than just another charity; it’s an opportunityto step out of your daily life, and to leap into fund-raising with a passionatepurpose. We invite you to embrace a worthy cause and to, in mostcases, ride your bike perhaps with newfound joy & appreciation.”
Now, for a few of your questions:How about that hour?
How exactly does UCI determine the distance of the Hour Record?Sounds stupid, but how do they precisely measure/mark where the bike ison the track at exactly one hour when the rider is cruising around at over30 mph? Is this the same method used since Merckx days?
CraigHere’s the answer from VeloNews’s John Wilcockson, who knowseverything about bike racing on the road and on the track:1. All tracks are set up with their exact distance, whether it’s 250,333.33 or 400 meters around, so counting the number of laps is an accuratebase number. Foam strips (it used to be small sandbags) are placed insidethe datum line around the two bends so the rider can’t cut corners.2. Each lap is timed to the thousandth of a second (or whatever). Agun is fired when the one hour is done, but the rider knows he has to continueat race speed to complete the lap he is on. With the precise timing ofthe lap, the officials know the lap speed, and it’s easy to copmpute exactlyhow far around the track he was on the hour. The distance covered on thatlast part-of-a-lap is added to the distance covered in complete laps togive the actual distance ridden in the hour.Because the rider is always outside the datum line, he actually ridesfarther than the recorded distance, but as all hour record attempts arescored the same way, the comparison is accurate.
John WilcocksonThe right brake pad for the right job
I use Bontrager Carbon rim wheels as race wheels with carbon dual compoundbrake pads. I was told by an experienced racer this year that usingthe same pads with my alloy rim everyday wheels will leave shavings inthe pads that will damage the carbon rims. Is this so? Changingbrake shoes after each weekend of racing is a pain. Thanks for yourreply.
I am sorry to tell you that your friend is right.
You have four choices:Change the pads whenever you switch back and forth between rim materials.You can make this simpler by getting a second set of pad holders as well.Especially with Campagnolo pads, it can be a bear sliding them in and outof the holders.Dig the little metal hunks out of the pads every time before using them on the carbon rims. This is also time-consuming and mind-numbing.Get another set of front and rear brake calipers. Keep one with carbonpads and one with aluminum pads. Switching calipers is much faster thanswitching pads; just bolt the brake on and clamp down the cable. Some brakesallow the barrel adjuster to slide out, so you can even get away withoutreplacing the cable end cap. Pricey way to go, but so are carbon wheels.Stick to using either only carbon wheels or only aluminum wheels for allracing and training.
