Say it ain't so: The Assploded Bike Parts Picture Thread.

I don’t have a good shop hookup here, but a friend may be able to put in a word that gets the crank failed.

Apparently a car did this but I’ve been told that these hubs explode on their own so who knows

Oof

Hang on is that a hub mounted in a stem there?

That is a perplexing photograph.
These are powered trailers?

Oh wait, the trailer tongue is mounted to the hub in the stem and is folding back+down in the pictured orientation.

In use it looks like this

Yes these. They do come in e-assist but not yet in the USA.

This is also The Way for trailing a bike
Attach spare hub to front bike
Attach fork of trailing bike to hub
Now you can go over bumps without torquing the heck out of the connection

how screwed am I getting replacements for my affected R9000 and R9100 cranks in 180mm length?

it looks like 177.5mm is the longest size of R9200

Just sand off the length markings and forget it ever happened. In a forum that has a rich history of overthinking it, you’re over thinking it.

Is that from a tiparillo?

The only reason I bought those Dura-Ace cranks at all is because they were modern production models in my size.

My 183mm cranks just arrived from Framework. Since he machines everything parametrically to order I picked that length to go with my existing collection of 180, 182.5, 184, 185 production cranks.

at some point there must be a fred vs drwelby crank length showdown

What about the 181 and 182 cranks?

It’s a shame about 181 and 182, I guess Fred isn’t actually about that life

I know we’ll both die on this hill, but after the last few years of working closely with a fitter who started pushing short cranks for aerobar fits, I’m firmly in the “you’re probably overcranking” or at least “it doesn’t matter as much as people think” when it comes to resisting downsizing. Physically, you’re an outlier for sure, but here I have seen 100% preference for shorter cranks than what would have been considered “normal” in years past. We rarely sell anything in 175 for drop bar any more and 160-170 probably makes up 85% of sales with <160 accounting for the rest. I can’t think of the last time we sold a 172.5 crank that wasn’t already on a floor bike.

But as always YMMV.
