    Diet: Low Carb and Ultra Cycling

    I rode the Marin Century yesterday, and attempted to do it without fuel, just Nuun-infused water. But I ran out of gas at mile 83. I stopped at the top of a hill, found some shade under a tree, wolfed down two Cliff Bars, and sucked down a lot of water from my hydration bladder. That gave me...

    extremely steep hill climb

    My small ring is a 34t Q-ring. I have a 10-42 MTB cassette for hills, and 145mm cranks for my knees. I don’t get slippage on clean, dry pavement even if the grade is well into double digits.

    Rotor Q-ring advice

    A 10-42 MTB cassette should make the 50/34 work fine.

    Diet: Low Carb and Ultra Cycling

    I rode 71 miles with 5600 feet of climbing without eating! I could've gone farther, but had to get back in time for a dinner reservation. Very cool.

    HPV Fun Day

    HPV Fun Day was organized again this year by Carole and George Leone. It was May 5 at the Hellyer Velodrome in San Jose, CA. Attendance was lighter than previous years, but it was still fun. Here's a photo of my Vendetta, sporting RojoRacing wheel covers front and back. And here's a photo...

    Your The Texas Time Trial Primer

    I took it out today on a paved trail by the Bay in winds that were 12 mph according to the NWS. Gusts pushed me around a bit on the trail. I had a couple stretches without gusts where I pushed it up to 32 mph, and it was no problem. Sprints will be first, and the NWS forecast is 4-6 mph at that...

    Your The Texas Time Trial Primer

    @LarryOz how high were the winds? I'm going to the event at the Hellyer Velodrome this weekend, and I've made @RojoRacing wheel covers for both wheels. But the winds are forecast to be 12-13 mph, and I don't want to end up on the pavement. What wind level is too high for front wheel covers?

    Longer chainstay = more speed

    As you raise your feet your entire leg will rotate upward. At some point your femur will be vertical (when your knee is maximally bent). If you raise your feet beyond that point, your knee (at its maximum bend point) will lower (not that this would be a practical riding position).

    The compact chainring front mech issues thread

    When I put a 50t QXL on my Vendetta, this problem went away. Admittedly an expensive way to solve a shifting problem, but if you are on the fence about Q-rings this might be the reason to spend.

    Zwift - Cruzbike Activities (races and group rides)

    Not good. My internet connection failed in the 16th mile. My power wasn't very good, but I continued to the end. After I got my internet connection back, Zwift only recorded the first part of the race in my activities list even though I did the whole thing, and none of it uploaded to Strava. But...

    warped disc brake rotor

    I don't think it was the 3000' descent on New Years Day. I suspect it is this descent: https://www.strava.com/segments/612463 which I do regularly on my hillier commutes. I'm in the habit of pulsing the brakes, but they got "spongy" recently (not using compressionless cable housing). And on...

    warped disc brake rotor

    Is it normal for them to get warped? A quick Google search turned up MTB threads about fixing warped rotors with crescent wrenches, hammers, etc. Here's what mine look like: This image shows the inner edge (toward the hub) of the rotor. It doesn't touch the table at any point around the...

    6-12-24 Hour World Time Trial Championships Perez vs the World

    @ratz the reason I ask is that it looks to me like my P1 pedals are reading a bit lower than my Tacx Neo. I would expect it to be the other way around. I have the Powertap mobile app. But when I run the Powertap mobile app during a session on the trainer, the Powertap mobile app just goes into...
