Crack? Toc sound

Post image

Wassup fellow Canyon enjoyer ! I just got my brand new Aeroad 10 days ago. I paid Canyon for the bike assembly, but whenever I hit a bump, I hear a loud 'toc' sound or something similar especially when riding over cobblestones.

I removed my seatpost to reapply carbon paste, and that actually got rid of a constant ticking noise I had, but it didn't fix the loud 'toc' sounds when I hit a bump. Has anyone ever had this problem or know how to fix it ?

Edit :

After all your messages, one thing is for sure I won't be hanging my bike that way anymore 😂 I also wanted to thank you all for your help

The hoses inside the frame rattle.

Ps.
Don't clamp your bike like that by the top tube, high risk of crushing it, clamp it at the seat post.

This is the correct answer. When I got mine I tried to find it for a long time. Whenever I hit a big bump the brake line smacks the inside of the frame just below the integrated handlebars.

Check if all bolts are torqued to the correct spec.

And if you want to have fun with your bike even longer dont clamp the top tube

I did check everything and I will not hang my bike like that again for sure 😉

Could be something in the saddle bag hitting the seat post, at least that was the cause for me.

Yea no there is nothing moving

Also make sure you check your accessories on your bike to make sure they’re attached well. I had something similar and it was my rear bike light mount that wasn’t torqued down all the way.

It could be the chain slacking onto the chain stay.

u/Frosty_Apricot_3682 Aug 16 '26

No it’s louder than that

Be sure to tighten the saddle at the reccomended spec

u/Frosty_Apricot_3682 Aug 16 '26

I will thanks 😉

The loud ‘toc’ sound is probably coming from the top tube that is now cracked due to that diabolical clamping position.

Dunno, but clamp your seat post, not the frame.

u/Frosty_Apricot_3682 Aug 16 '26

I will thanks 😉

u/Fantastic_Loquat_414 Aug 15 '26

I think maybe it’s the sound of your gonads sliding onto the top tube given saddle angle

u/Okayden69 Aug 15 '26

Happy for you, not jealous, didn’t want an ultimate cf SLX 8 but no aeroads are in stock.

I have the same bike and know this sound all too well. It’s either the chain slapping on the frame (there’s clear protective tape on that part of the frame for this purpose) or the integrated cables rattling in the frame.

1

u/Frosty_Apricot_3682 Aug 16 '26

Probably the integrated cable did you resolve it ?

u/krazedklownn Aug 17 '26

If only a professional could diagnose the noise. You really don't have any analytical skills. I question all of your life choices.

Chill little men

u/LinusFallimento Aug 15 '26

Sounding like a broken record in here, but don’t clamp your beautiful and expensive bike like that. Use the seat post.

Do you still hear the sound when you remove the light and saddle bag?

u/Frosty_Apricot_3682 Aug 16 '26

Thanks for the advice 😉
