    Campagnolo 11 speeds

    Campagnolo says that the Centaur and Athena groups aren't interchangeable with the upper end groups such as Record. But another man said that he had been running Record levers on Centaur derailleurs since 11 speeds come out. Does anyone else know anything about this?

    Carbon rims and rim brakes.

    One of the reasons I like aluminum rims is that I get good braking. Carbon wheels with rim brakes have a lot of problems but most people do not stress them enough to have problems with them but carbon wheels, rims brakes and downhills don't mix well. View...

    Mick's bikes - pleasanton

    A week ago I was moving along at a pretty good speed, hit a pothole, got a pinch flat and had an instant pinch flat. I safely brought it to a stop and sat down on the curb to repair it. At the time I was only interested in getting back on the road so when I filled it the #ing CO2 filler didn't...

    Ftp (full time power)

    Most people would expect this to be the value of power output that you could maintain over an entire ride but it isn't. It essentially is the amount of power you can output over only about 20 minutes. So if you're out on a Century or the like you most assuredly cannot put out power like that...

    Giveaway

    I accidently bought a BBright FSA gossamer EVO crankset. If someone has a good use for this (this fits very few framesets so be sure). If you can use this it will cost you the cost of shipping. I would suppose that's somewhere around $20 for boxing and shipping since the original boxing got...

    Didn't ride today

    I was working on my new F55X Felt gravel bike in the garage and I had decided to install Slime innertubes in the 35 mm tires. Well, the innertube punctures with a couple of small holes from the mounting. Why that was I certainly couldn't tell you. But perhaps more importantly, these punctures...

    Shimano di2 electronic shifting

    I can hardly believe that there's no thread about this so I'll start off: I was looking for an Ultegra group to put on a bike. I've been Campy for most of my life but after 8 went to 9 and 9 went to 10, keeping the damn things in adjustment so they were shifting properly at least most of the...

    Technical advice on compact crank

    I presently have a Redline Conquest cross bike. It has an "oversize" shell width (73 mm). Presently it has BB-MT800 cups on it. I like the idea of a 24 mm crankset shaft but the Reynold's compact crank I tried to install was too narrow. I guess that the Ultegra has a shaft diameter of 24 mm but...

    More on deep aero carbon tubeless rims.

    During the last episode before several people thought changing the subject was more important than the subject, I explained that I had got a set of deep aero carbon clincher rims. These worked very well. And because of the increased aerodynamics of the rims they didn't react to even strong side...

    3m nexcare tegaderm

    In the thread "Crash Test Dummy" I explained crashing. I explained how I had abrasions lightly on my left elbow and hip and some pretty serious abrasions on my left knee. For the first three days it was getting progressively more painful and then after that it didn't appear to be getting any...

    Crash test dummy

    I was up about 1000 feet yesterday in a part of Oakland called Montclair. I came down via Broadway Terrace. Near the bottom a car kept running up on me only to have to slow down for speed bumps and then taking a run at me again. So I just let off of the brakes and did the bottom turning steep...

    Winter and riding

    My brothers use trainers. My older brother just had a heart attack and I bought a Schwinn indoor trainer that has everything automated. My young brother (59 is young?) uses a CyclOps trainer because of the rain and cold. He says that it really improves his spin. I simply cannot STAND sitting on...

    In memory of paul sherwin

    How long have we listened to the voices of Phil Ligget and Paul Sherwin describing the Tour de France move by move? Paul died in his sleep yesterday at 62 years old. Those of us who have continually watched the Tour year by year could tell that Phil Ligget had been getting more and more tired...

    Bickering

    What in the hell is going on here? First CampyBob wanted to argue about an off-the-top-of -the-head calculation such as we engineers do all the time as a first approximation. It was a total insult to him. Why? Then Froze started chipping in because I was so forward as to have actually published...

    Power meters

    Today pros are using power meters In training in increasing numbers. So what are they are how accurate are then? There are many different kinds using several different methods. The original method used was hub mounted power meters. These are approximately 1.5% accurate. This is a little...

    Ceramic bearinjgs in bicycles.

    There are some major differences in ceramic and steel bearings. Basically they come down to weight and smoothness. The weight of the bearing limits the speed at which it can roll without developing too much heat and breaking down the lubrication. The majority of the weight of a sealed bearing...

    Danger of carbon fiber wheels delaminating

    I previously bought a set of 50 mm deep Carbon Fiber rims. These were clinchers and were 23 mm wide on the brake surfaces. These have performed faultlessly. But I didn't want to have to carry around all of the 2 lbs of flat repair stuff - the Topeak bag, multitool, two spare tubes, two CO2...

    Wheel warning

    A friend came over with a set of new Mavic Kyserium Elites. These wheels were round and true but the inner measurements of the clincher rims were REALLY narrow. He also had a set of Panasonic 23 mm tires. I attempted to install these tires on these rims and it was extremely difficult to get the...

    Group riding or not

    Riding in groups is pretty normal. But you have two sorts of groups - those who stay together and those who are racing each other. The first normally becomes the second as each person's abilities increase with experience. The huge fires all over California had turned the skies reddish in the...

    Where'd everyone go?

    There appears to be only two others that are constantly posting. Froze is upset because I have a lot of cop friends including my best friend who was an NCIS group leader and transferred to being a Federal Investigator to get a posting back in the USA, my cousin the prison guard at San Quinton...
