Your suggestions please!
19 or 22 tire width for tubular Continental Competitions mounted on 700cm HED3’s (front & rear)?
I’m 6’5", 208lbs riding a P3, if that makes any difference. I’d like to go 19 on F & R, but i don’t know if i’d be too squirley. What’s the aero/safety payoff?
Sprints and Oly’s this year.
Thank You!
Aerodynamics are a significant factor in tire selection but so is the road surface you are on.
A 19mm may be suitable for course with good pavement but on rougher pavement the 22mm’s may actually work better.
I used 22mm tires in IMNZ but Bjorn Andersson used 19mm pumped up to 150 psi I heard. I wanted more comfort, he wanted more speed.
To an old MOP’er like me, speed = comfort.
The general rule is to match the rim width. I’ve heard conflicting reports about the actual width of a HED3 so I recommend you measure it yourself.
the Conti Comp 19 fits mine perfectly, I would suggest it highly:

and pumped up to 150 - 160 psi.
Are those Bunnyman’s break covers?
Nice!!

One thing to watch out for is clearance. My conti 19mm work just fine w/H3s & my Profile ACD, but 22 mm rub just the tiniest bit (and for training, Mavics CPX 33s don’t work, while Velocitys do).
Hmm. What about the post I read on the forum awhile ago cautioning against using tires that were inflated over 110 psi on HED3s because of the danger the tires would blow off the rims?
I emailed Hed on this same issue and was told that 22mm would be good but 19mm better depending on weight and road conditions. Never got around to getting further info so went with the 19’s Comp GP. Haven’t really ridden them enough to give you credible feedback.

That applied to only a certain tire brand or two. I can’t remember which ones though, but not mine!
i thought we were all supposed to get rid of our front h3’s and buy 404’s because cobb said so! 
Is that a ZIPP carbon cover that used to be on the rear brakes of a 2001/3001 beam bike? Or is that something homemade? Either way, nice. What brakes do you have under there?
NOT! I’m still riding my H3 in front. And going to the Super-Lite Carbon H3 as soon as they’re available. Seriously, you’re going to switch based on one person’s opinion? Come on. I’ve had ZIPP 404’s and raced on them. H3’s are faster, no matter what anybody says. Ask Gary Tinley and other really fast people. Spoked wheels amplify the turbine effect at speeds of 25+ mph.
i agree. a while back cobb had everyone in a panic dumping their front mounted aero bottles and putting them behind the seat, then dumping that system and putting them on the frame, then buying front mounts again because maybe it was good after all. unbelievable!
if people freak out that much about a water bottle, i can’t even imagine the panic that his little article on wheels must have created.
a little less time analyzing, a little more time training.
Off topic from the thread. . .Folks, pay attention to Gary’s pic. Pay CLOSER attention. . .
Although I don’t necessarily like all of his choices. . .it is painfully obvious that thought and research went into all of his equipment choices AND preparation. Even the valve holes are covered on the H3. This is the way to build and prep a TT or Tri bike.
If I see one more P3 or somesuch high dollar, high aero factor bike set up with a mess of cables and gear hanging all over off of it, valve holes open (on discs and other solid wheels like the H3), etc. . .I think I’ll puke.
two additions in the works not shown, black TT chainring and a Zipp 909 disc (dimpled)
That is a '03 Corima disc in the photo with HED stickers (for sale by the way, $400 , with a 22mm Conti Comp, low, low miles - email for info)
I will say that I have been experimenting with various TT equipment, lately the Campy aero bottle, which I run empty for local TT’s, works nice as I can drink right up to the start, then I empty out the remainder.
I am switching that out to a regular bottle in preparation for 40k and 56mile TT’s this summer (train like you race … right?)
Having gone through several saddles, I have been with the SBC Ti for the past 3 years, and will get the carbon model when I get around to it.
The Abici was my #1 choice because - 1. 74 degree seat angle and I liked the geometry, 2. custom cut seat mast and integrated cables, 3. great service and warranty, 4. 3 lb frame … I like aluminum
Thats a Zipp made brake with the Zipp carbon cover!
One on eBay just went for over $200.
I just cannot, ever, I don’t care how much time saved – bring myself to mount any sort of bottle on the front end of my TT bike. I like a clean front end. AIN’T GONNA HAPPEN.
"I wonder why? What with the large frontal profile and sharp edges, it can’t possibly be more aerodynamic than a standard brake. Maybe somebody really needed it because it is a centerpull? "
You might be surprised how “certain” things may look non-aero, but test well in the wind tunnel: http://www.johnhowardschool.com/johnhoward/clinics/WindTunnelJune2004.html
