Lately, sometimes/once per ride probably, the front fork (?) of my bike makes a loud noise. A relatively loud "tick" - I cannot pin point when exactly. One time when riding hard over a bump in the road and it's there, riding again over several bumps no "tick"at all. But then again it can also happen when on a relatively flat, smooth road. I thought it may be some small stones that hit the frame. Anyway as it happens "regularly", I carefully checked the front bar/wheel/re-tightened everything and also checked the saddleclamp/chain/chainstay, thinking perhaps it's is not coming from the front?? I closely inspected the front fork which looks and feels OK, no scratches/dents/or whatsoever. Should I just ride and forget about it or have it checked - I am talking about a Specialized carbon Roubaix. I am reasonably carefull when riding but should this be a reason to get the bike checked as I don't want to crash due to a technical failure.

Random sporatic sounds are almost impossible to diagnose without hearing them, then sometimes the tone helps. It's possible that something is moving but only with the higher energy of a bump. It could be an insufficiently tight crown race, or the axle shifting in the dropouts as the two blades flex independently of each other, or up in the handlebars or stem.

As long as it's rare, you're probably OK to ignore it or try simple remedies like increasing the tension of the front QR. Other than that there's just not enough to go on, which is probably why you're not getting a ton of suggestions.

Grip the wheel tightly with the front brake only. Rock the bicycle forward and backward to see if the click is caused by looseness in the lower headset bearing.

If you have a computer magnet on the front wheel check to see that it clears the sensor.

I found the source of a nasty rattle that happened from time to time in the front part of the bike: presta valves and presta valves nuts. Threadless presta valves can rattle in the rim (some duct tape on the stem of the valve should fix the problem), and the nuts on threaded presta valves can come loose and also rattles.

So check the valves for movement or loose nut. But it's more like a rattle but can sound like a tick also.. depends.

Thank you - much appreciated input. I'll run through your suggestions.
