The Ms got a new road bike not long ago with an Oval Concepts 527 wheelset. She has a persistent clicking noise coming from the front wheel after only a thousand or 1500 miles, and I can't quite diagnose it. Any ideas would be appreciated. It's definitely the front wheel (Oval already replaced the rear wheel for two snapped spokes in 400 miles): it clicks rhythmically and at a rate proportional to the speed, and is unrelated to the drivetrain. The wheel does spin freely, so the noise doesn't seem to be related to anything causing a drag.
Here's what I've tried so far:
- checked wheel in truing stand: it's not out of true and has no appreciable bumps on rim or tire (stock Vittorio road tires 700x25C)
- checked magnet to sensor distance on cyclocomputer: it's about 5mm
- tightened magnet
- swapped sensor out entirely
- "plucked" the spokes to compare tension: they're all pretty close
- took off the plastic reflector
- put bike in stand and checked for tire contacting forks or brakes: plenty of clearance
Some additional information: it takes good ears to hear the click when the wheel is off the ground and spinning freely, but when there's a rider it's audible from several feet away. If I stare at the hub while spinning the wheel v-e-e-r-y slowly, it looks as though it clicks every time one of the Oval logos comes around the top of the hub.
I'm thinking perhaps too little grease in the hub, or maybe an out-of-round bearing, but wonder if it's something that won't necessitate a trip to the LBS for warranty service. Your thoughts welcome and thanks.
