If I have to worry over conductivity on my bicycle, its too damned cold. Nope, I'll sit by the fire. Weather looks great today. Light breeze and a clear, blue sky.
So... you're telling me to keep the aluminum handlebars to help keep my hands cooler here in Florida?
And actually, by changing the interfaces and efficiencies of them you can change the HT.i.e. aluminum bar to plastic/rubber grip, with glue as a bond would insulate from HT from the bar, but the greater problem is from the sun on the backs of your hands where all the blood is. Shade that. Light colors with ventilation.
Always light colors, white if possible, most months here. I won't buy black cycling shoes - only white, built with plenty of airflow, and only own one black-based cycling kit that was my shitty-weather kit until one of the bib's seam let go.
I thought about it. Still not fan of weight bearing carbon components and budget conscious these days due to the s*tstorm of changes and expenses that followed the TBI.
I have returned from forced exile with a miserable head cold that has totally flattened me. No matter, there is 8” of white, frozen sadness out there with a high of 18 f. I did get to watch the Tour Down Under and, without spoilers, every time I see Patty Bevin in action I have to think his mechanic has given him the wrong bike.
White shoes are for pro poseurs only. If black shoes were good enough for Joop Zoetemelk, they are good enough for me.
I don't know if they are scare-tactics by competing expensive brands or not, but there are a number of reviews of different brands of inexpensive carbon-fiber road bars shattering/breaking under normal loads on Amazon. I've been looking at them, and may go a step beyond them.
I have a soft spot for a custom painted orange F10. No bank yet, so. I make due with blue, The bar tape is looking tattered and finish end is feeling that way as well. I should put that orange tape in there. I got out for a bit today. My usual loop up Marguerite. Wind out there from about the north, or northwest kept things interesting.It has been a long while since I have ridden in such heavy wind and gusty conditions. Took some doing to stay pretty steady and true at times.A few tics shy of three hours. Good steady work that wind.Enough elevation to complete the January climbing challenge. Felt pretty good with just leg and arm warmers on in low 60's weather. In the shade was nippy for sure. That tailwind down PCH on the way home was nice. And hammering around the harbor loop a guy in an Audi wagon came by with a thumbs up telling me he could get a good draft off me. Wait? The whole of the day parking at Doheny was closed from flooding. They cleared just enough sand and rocks so bikes could get into a good hammer through there. A strong woman came down the hill to the path along the Coast Highway as I got there and slid by me. I finished my refreshment and spun the big ring up with that nice big tailwind and caught her. Then pushed myself by and she sat on for a bit.But, when the road makes this little curve and the wind is just that much less, I decided to see what the legs had.That was good for 25 mph and a bit. Five minutes of that and my body needed rest. HR averaged 157 through there.She caught back up to me as we got to the little jump hill and climb back up to the elementary school. I dropped her on the climb.I'm getting stronger.(she was wearing a large backpack though) Once home I'm not really even hungry, just one magic bean at Salt Creek too.Not really tired, a little muscle sore, but not bad.I hope there is less wind tomorrow, I'll try for another one.66% of my time was in zone 2 so still burning the bulge.
@Gummee!I know they are tough. I’d have to get a high end one as even a Raceface Turbine has too much wall thickness to accomotate the expanding plugs needed for the pogies.The cost in money and time doesn’t seem like it’s worth it for me right now. @Mr Headthat’s a nice RR :)
有人可能会认为,使酒吧不仅仅是形式ing a tube of carbon. What usually causes failure, especially but not limited to cheap off shore carbon, are forced produced by a crash or forced produced in a clamping area. Precisely the reason for such low torque figures on the pinch bolts of stems and seat collars. But there are other forces at play, namely a bending stress, where some fibers are in tension and the opposite fibers are in compression, depending on the direction of the force—and a horizontal shear stress. Mr. Head could probably enlighten us a bit more if it’s the tau that should concern us more. I have a set of Easton carbon bars but I have relegated them to the city 29er and use Thomson titanium bars on the mtn going 29er. Mostly because it’s well nigh impossible to tell if they have suffered structural damage from an external visual test. One really needs an ultrasound test to detect the sort of voids that occur when a carbon bar is flex hard up against the clamping area of the stem. If you take your fork out of your bike, you can easily move a tight fitting washer up and down the steerer tube. If you install your expanding plug and tighten it down not very tight, you will find it nearly impossible to move that washer past the bulge created by the expander. I don’t think many people understand how much that carbon gives up in hoop strength. The one good thing about carbon is it can be made with very poor QA/QC standards and still hold together. It’s amazing how wrong manufacturers can get it and still it somehow manages.
If I were building cf bars they would be filament wound. With a few sections of tape.Tape in CF world is prepreg with all the toes in the same direction. Layer of Kevlar on the outside at the clamp.But that would be expensive and take time.Check the YouTube of GCN and Look frame builds. See all that hand work. That is money.Also why handmade Italian steel frames are big money.The history of composites begins back with Michelin and tires.Yes there is YouTube. Worth a look with all that snow and nasty weather.I would not buy cf bars based on price alone.I have seen bars fail at speed. It was not pretty.
I do have this set of CF bars on the Pinarello. I cannot imagine they will stay on forever. I don’t much care for the shape— I know, “ooooh, so aero.” And the bar tops are slippery. But they came with the package. One thing Pinarello did get spot on was the top tube length. I run 13s and 14s on every other frame to get the reach. Not necessary on this ride. I have no idea how light the bar/stem is or isn’t. The 3T cockpit inspires much more confidence and cannot be much heavier. The entire bike is something like 17.4 lbs as it sits there anyway. No point in counting grams.
I've had carbon handlebars on my road bike since 2006 or so.Replaced last June with cheap Chinese brand because they are cheap (sub $50), aero, have internal cable routing and seem to be pretty light.They have large flat sections at bar top that really comfortable, where I place my hands the most during most rides.No, they are not as stiff as my 12 year-old, 46cm wide carbon handlebars that I paid over $100.But I'm not sprinting nearly as much as I used to, I don't race anymore, I don't go on group rides with large group sprinting from one light pole to the next. I don't put significant amount of weight on the handlebars and I weight about 170 lb. with all my winter riding gear on.Yeah, in the drops I feel it moving when I grind up a steep hill, but not enough to worry that I'm loosing control of the bike or handlebars falling apart.With any equipment on a bike, we need to determine our own usage and risk, inspect the equipment regularly especially when they are superlight in weight.
adjust your top cap so it’s aligned with the “p” logo centered on the bottom, you’ll go faster. nice bike, btw. best regards, johnnyg
My reasons for not running carbon bars isn't strength, it's racing. The old adage of 'only race what you can afford to replace' comes into play. 事故发生…… I already have a pair of Zipp rims that need to be fixed... Ditto with one of my chinese carbon rims. Those darn tree roots got me! M
