Andrew, have you seen any or many Trek bonded aluminum fork failures?

I have not.

When we sold a lot of Trek product here, the bonded aluminum
models all had Tange CrMo forks. I'm not an expert on the
later import models.

Thanks. The idiot that is selling the fork has had it on the local market for over a month and it never occurred to look in the spam folder where my replies have pretty obviously been sent.

Last week you were looking for a chromed steel road fork.

A new aluminum fork with a warranty in a box is not all that
expensive.

Sounds like his email client is pretty smart.

That puzzles me too. You are incredible patience in answering Tom's fork questions. Kudo's to you.

Lou, it is dry I am going for a ride (CF fork bike)

As I said Lou, there are countless pictures on the Internet of failed carbon forks. and other components. (I will tell you the truth, I have no idea if these were structural failures or quality control issues. Could you tell of your bike is breaking without ultrasound inspection?

I am permanently disabled and so is the cop who managed to get me back from the last step from death. I'd just as soon that you aren't injured. So don't make this appear like only crazy people are afraid of carbon fiber. Hambini has shown NEW bikes that have broken and not just the older ones that are in this collection.

I am aware of the CF properties and therefor I buy my bikes new from repectable manufacturers with in house quality control ie. https://m.youtube.com/watch?v=6KepKZ80DCM (from around 11 min) or ENVE on my gravel bike. I never will buy a second hand CF bike. I suggest you do the same, not necessary a CF. I would stay away from second hand bonded AL forks. I would go with Andrews suggestion and buy a custom Waterford steel fork.

Hambini is a clown. I am not impressed.

Hambini is a mechanical engineer that works in the aerospace industry mostly with jet engines. You can chose to ignore the facts and instead listen to others, and indeed BECAUSE those failures of carbon fiber have been high lighted and pointed out, they have improved but light and strong are opposing features and resin will ALWAYS age and harden moving the pointer more towards the less strong side of the game. It is up to you to protect yourself so by all means remain safe. I wish for you a long and uninjured life and not like too many people I've seen including myself. I am sure you would NOT like to have to take the medications I do to remain functional. Or to have a finger amputated so that your hand is functional like my friend. Remember, you're not riding a Tour de France after which all of the framesets will be thrown away and replaced with new one's from the sponsor.
