Okay, guys. Here's where I admit what a total wuss of a nervous, incompetent, old man I am.

As some of you know, I recently acquired a super-nice set of wheels. They are about 1440g, 35mm deep and I have 25mm GP5000s mounted on them. They are noticeably faster than the decent set I was riding before, but I have one complaint. To wit, they scare the snot out of me descending on rough pavement and/or gusty winds. Yesterday, I had a big tailwind on the homeward leg and had a bunch of 30 mph stretches in the drops where I wondered whether I was going to be able to hold it together and stay out of a death wobble. Some of this was clearly mental and went away when I reset my position, shifted weight aft, and relaxed my arms, but I've never had it so bad with any other set of wheels. My inclination is to work on the mental part with progressive exposure, but I am also concerned about the risk. Any helpful suggestions? Anyone think 28s would help?

I will PM my address to you. Ship me the offending wheels and tires. I will test them extensively, and return them (postage collect) with a full report. :D

I would have the tension checked just because it's the easiest of solutions. Maybe try a different tire just for the process of elimination.
Its spooking you because speed wobble is friken scary, and hitting the ground at 30 mph is not fun.

Busy day of telemedicine, that’s why I am late.

MoAlpha agree drop your PSI and relax. Should improve with a few more rides.

datlas in a flash of brilliance today I conceived of an invention for you and your ilk: a handlebar mount to hold your device so you can do tele-medicine consultations whilst riding.

How big do you figure the market is for such a product?

Might be time to call your sponsor?

Brilliance? I do not think it means what you think it means.

Made my own sauce with spinach and my secret blend of herbs and spices.

They ridiculed the horseless carriage, too.

My LLS generally has a couple duey bikes out front. :lol:

*duey = DUI (Illinois)

I think if you're getting a wobble you never had before and the only change is the wheels, maybe the wheels are flexing a bit.

There have been threads on wobbling and many times there is no apparent reason discovered. It seems that certain combinations of bike/wheel/rider sets up a frequency that causes a wobble.
I had a friend who had a Miele with a wicked death wobble and nothing he did would stop it so he got rid of the bike. I've never had a speed wobble on a bike. Lucky me.

Friken sweet. Nothing like some good fitting footwear.

If I need a sponsor, it's for chocolate.

put in a round of wedge.

I'm back on to calorie counting, and while a beer will always be the first indulgence of a given day, chocolate is for filling in the corners of the caloric budget.

I may be made of 50% eggs, 50% chocolate.

Ah.

OMG. Dream car alert. They don't even put a listing price on it, so I guess that's a "If you have to ask, ..." kinda situation.

Chocolate is essential. I would give up water first.

Damn things better not be flexing with all the hype about how stiff they are.

Even though I have a slight cold (no covid symptoms) I couldn't stay off the trainer and Rouvy... so picked something short and easy for an easy spin - Lava Beds. This is a route in Oregon that is a bit rolling and mostly downhill. Only one very easy climb, and well, halfway up I've already forgotten I was going to take it easy and attack it. So much for an easy spin! :rolleyes: It was super short though, so not much of a workout and not enough to really fatigue me, but it feels good to work up a bit of a sweat!

But dammit, couldn't get my new CLIMB to work. I can pair it to the CORE, or adjust it manually, but it never changes automatically... I must be missing something. Updated the firmware first thing. Enter wheel size and wheelbase in the app. But it just sits at what the app says is -1.9% (it's not, it's level, as verified by measuring axle heights). Have a support ticket for it.

Maybe they're so stiff that you stiffening up leaves no place for the wobble energy to go?

Pissed off that I forgot to get some dark chocolate when I was in the store Tuesday.

Should be plenty on discount after the weekend.

That’s why I am thinking of lowering the tire pressure a little.

I've settled on classical guitar. For the time being anyway
And I built another wheel today. Still needs to be finished up
