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? I don't know how easy it is to inspect bearings on a Shimano dynamo hub, but I'd be very reluctant to try opening the hub until I'd eliminated all other possibilities. My guess is that your noise originates elsewhere. Things I might check are wheel reflectors, if you have any installed. They can rattle against spokes in strange ways. Check fenders, if you have them; check each attachment point, and also check that the fender is not slightly touching the tire. Check any bags or baggage on your bike. (I've had mysterious noises come from items rattling in my handlebar bag or saddlebag.) Check attachment points for all accessories - water bottles and their cages, racks on the bike, lights, bells, etc. I'd also advise re-checking the tightness of your axle nuts or quick releases, your headset, handlebars, stem, etc. even though it sounds like your problem is elsewhere. And I'd lightly grease the stem and bar attachment points. Good luck. It can be devilishly difficult to track down an intermittent noise. - Frank Krygowski |
