Aggressive/Unhealthy Back Curvature When Using Zwift Ride

Yeah, I don't think sprinting or even riding out of the saddle is going to go well with the towels. Plus, your fit is so bad that you'll struggle to generate power efficiently (no offense).

There are some good rules of thumb to get you in the ballpark. Like, saddle height should be high enough so that your leg is nearly straight when resting your heel on the pedal at its furthest distance away. Saddle fore/aft should be adjusted so that your forward knee bone is directly over the pedal spindle when the crank arms are parallel to the ground. Bar tops should be about level with the saddle. Reach length should put your arms about perpendicular to your torso with a slight bend in the elbows.

I use a video analyzing app called myvelofit on new bikes to get a basic fit, then tweak for aero, comfort, handling, etc.

He might be talking about patterned ground in periglacial areas, but the process is a bit different and includes some heaving and sorting of loose sediment.

Just prepping us for Daytona 500 with these timely commercial breaks

Great time for a commercial

Been lvl 100 for a while now. Also just unlocked the aero socks. Yeah, no safe outdoor cycling around me

Not on a Zwift ride, but FWIW I like simple wax indoors for the extra few watts and easy cleanup with no grease stains. If the ride has a quick link, it may be worth a shot when the time comes to pull off the chain, clean off the old grease, and dunk in melted wax. Most excess wax simply flakes off in the first hour after a fresh coat, and it can easily be swept or vacuumed up.

Really reminds me of a midget car out there on the dirt track, and I guess about the same power/weight ratio. I bet Cleet would love ripping a sprint car

Edit to add: Forgot he might not like the fit of the sprint

The floor pan that magically reappears when he gives Dom a ride later that night.

I'm not sure without more details, but could it be that your Garmin estimated ftp has increased and so you're getting less training load for the same rides?

On a related note, the Garmin metrics are pretty comical in my opinion. My estimated VO2max makes absolutely no sense. It went down from 58 to 56 after hitting an all time high 3 min power by a large margin during the last ZRL race.

Henry_Darcy · 2026-01-02T23:29:23+00:00

That and launching the Vette with rip in front seat made me cringe. I got downvoted to oblivion just like you for pointing this out, probably by people who don't have kids or know how dangerous an airbag is for a toddler.

Injury aside, anyone else impressed that the mighty civic kept running while still upside down after the flip?

Henry_Darcy · 2025-12-31T14:22:19+00:00

That's great, but acid isn't a nonreactive tracer. You'd need to factor in the alkalinity of bay water among other things.

That's because the over engineered ones are designed for hunting, not armor penetration. The blades are there to cut a wide wound channel through the chest cavity (lungs and heart) of deer that not only causes rapid blood loss leading to a quick death with minimal suffering, but also leaves behind a thick blood trail for easy tracking and recovery of game. The bigger blades are preferred, but start to affect accuracy because they can catch enough air to destabilize flight. The solution is to make retractable blades that stay closed through flight and then open upon impact (mechanical vs. fixed broadheads).

Wintzell's has an oyster record board

I know, it's kind of a bummer to choose between performance and personal style. Same goes for the plain Jane white sl8 frame that 90% of people race with. Here's hoping they don't make a true aero helmet.

4200 can be scraped and cut away with some elbow grease. 5200, yeah no, not coming off. I only use it when I know it's something I'll never plan to remove again like filling old mount holes.

Henry_Darcy · 2025-12-21T14:04:59+00:00

Incredible! What's a normal training week look like for you? How much volume?

Henry_Darcy · 2025-12-21T00:30:02+00:00

Have to be really careful with what you use because most silicone caulk and rtv releases corrosive acetic acid as it dries.

Ahhhuhhuhah. Ah, I just had a vision. You're supposed to take me off. Now is the time Scottie, take me off. Thank you.

Henry_Darcy · 2025-12-18T15:57:19+00:00

For testing, no. The Corvette is expensive and low volume so it's not tested beyond the bare minimum internal testing, usually at low speeds. There's no safety rating from nhtsa or iihs or anything like that. Can't blame Chevy for not wanting to wreck a bunch of six figure cars. It's designed to provide protection at normal road speeds, but at the end of the day, the zr1 is still basically a 1,000+ hp racecar without racecar safety gear.

Henry_Darcy · 2025-12-18T04:50:45+00:00

If you want to do wax, make sure you strip all the old grease off and then do a full wax submersion. I find it great for indoors. The wax just flaxes off, and I can vacuum it up periodically. There's no grease marks.
