He did. Not going to fast either as it snapped.
There’s been quite a few of these on Zwift riders and probably to do with people using old bikes on their trainers.

Don't use sharp blades when removing old tape.
Loosen brifter clamps properly when fitting or adjusting (don't graunch them around the bar).
This way you will maintain the anodic coating and reduce the risk of the onset of corrosion as a result off contact with warm acidic/alkaline liquids.
Also, wash your bar tape with soapy water regularly and dry with a towel.
Otherwise inter-crystalline corrosion may sent in.
Add constant stressing movements from bar rocking, which is probably more pronounced strapped into a turbo trainer, and then you get the onset of stress corrosion which will concentrate on any week points caused by the above.
Then, before you know it, the stress fracture starts and propagates very quickly.
Ultimate solution is either carbon or steel stem and bars
Or
Simply look after your kit, even if it is a hack bike.
Hate to think of the consequences if the turbo hack bike was being used on the road at the time of fracture.

Always remember the famous words form the American Marines Instructor.
"Thats your rifle, thats your gun.
Thats for fighting, that for fun!"

Ignore this lesson and you may die!

Good to see BKool is now back on line because we are all stuffed with our evening meal and sat on our sofas.
I was lucky that it seemed to crash as I was warming down. Thought I may have lost the ride but looks like it has saved OK. I was hoping to do a second ride but that clearly didn't happen! Will try a ride tomorrow again after household chores

I was all booked up and ready to go to Barcelona in early December with the family. But then I got overwhelmed by a tsunami of crap at work. Bit gutted at the time. The missus wasn’t exactly overjoyed either...

But on reflection, going there with my bike rather than my family, does have its own appeal! :smile:

(And no @AAAC, ‘my bike’ isnt a slang term for my mistress!) :stop:

Go when it's warmer instead.
You will love it there even without a bike.

And.....never have steel/alloy bar/stem combination without a sleeve to stop dissimilar/galvanic corrosion. AAAC 76C careful..i get a bit excited now specialising in NDT/Chem processing! Don't get me going on Ultrasonic inspection of carbon fibre..etc etc

I took my old bike and we loved it.
Walked around all day looking a beautiful things, well at least I was, and at big unfinished cathedrals and stuff.
We ate loads of food and went into a lot of shops, cafes and even an aquarium.
We also went on a cable car ride and then visited restaurants in the evening and ate expensive food.
And when done we went back to our expensive hotel and drank expensive wine.

Yep, leave the family at home and take your bicycle instead!

Don't worry, I won't but I'm sure I can find some nerds in the factory who might want to engage in such nerdy banter.
I went to a meeting about surface treatments prior to bonding some strengthening plates onto the transition joint on a Wildcat (like a transportation joint but the tailboom is not a separate structure) and I couldn't believe how excited they got about gluing stuff.

PS: What sort of sleeve would you recommend, shirt, jumper or jacket.
I expect a jacket or jumper sleeve would be too thick so it must be a shirt sleeve.

We even have different glues and not just araldite and gorilla snot.
