Front cracking noise

Hello all, For a few days, I have noticed a new cracking noise that seems to come from the front of my bicycle. It only starts when I am riding at more than 25 km/h, and it is the same no matter how bumpy or smooth the ground is. I have already experienced cracking sounds from the handlebar in the past, but it does not come from it in this case, as it continues even if I release the handlebar and ride without the hands. The fact that it is related to speed makes me wonder if it could not come from the front hub ball bearings, what do you think? This is a Shimano hub dynamo, do you know if its balls can be replaced? Noises on bikes are notoriously difficult to track down as they are often not where the noise appears to come from[1]. My first port of call is to loosen and re-tighten *every* nut/bolt on the bike. Be systematic, it doesn't take very long. As a plus point you'll find the missing/stuck ones :-) After that, start disassembling and checking from the perceived area of the noise, in this case handlebars, headset, from bearings, maybe BB. Good luck, I have come close to Postal territory trying to find an annoying creak. [1] Having someone cycle next to you and have a list sometimes illuminates the situation. |

In general, loose nuts and bolts do not cause irregulate and non-cyclic noises. Though you are quite correct that most noises on a bike are from nothing more than poor maintenance. |
