    Clicking

    Hi guys, I have a question about a clicking noise in my new singlespeed.

    The clicking is almost always perceptible by ear, but sometimes just by feel. It seems to be at the bottom of the pedal stroke, but not every stroke. Also, it seems to be worse/more often when under load (ie, out of the seat).

    I'm not sure if this is relevant or even abnormal, but also, when I roll the bike backwards, I feel a click at a certain point. I can't hear it, but can feel it.

    I've lubed the chain and bottom bracket, changed/tightened pedals (my old pedals are on another bike which does not do this) and I honestly don't know what this could be or what to do.

    Any help is greatly appreciated. Thank you!

    Prolly coming from the BB cup/frame interface, common hassle.

    Remove the cups, ensure the BB tube doesn't need facing, reassemble with heaps of grease and tighten it up to buggery, cross fingers.

    Or if you're lucky it's just from the BB spindle/crank arm interface; try pulling your cranks, lubing and reassembling those first.

    Clicks and creaks can be fiendishly difficult to trace & cure. And despite a SS being "simpler", actually adds a dimension. I think I'd start by checking the chain for tight spots and binding. If nothig else, it's pretty much the only check that doesn't require disassembly.

    You say you lubed the BB? Does that mean you have a cup & cone BB? C & C BBs do need a bit of preload to behave themselves while pedalling. You can't go for that finger-tight feel that might work for (nutted) hubs.
    If it's a cartridge BB, then greasing the threads, or even a few turn of Plumber's tape before assembly is a common recommendation. If you have assembly grease(graphite, copper, aluminium - as used for brake pads in cars etc.), that can work better.
    Then just continue to work your way through the bike. Pull the chain ring off, clean and lube mounting points, reassemble. Try another pair of pedals.
    When you're out of the saddle you're usually pulling harder at the handlebar - something in that region might actually be involved too.

    Oh yeah, try the chainring bolts before pulling the cranks.

    You can try to isolate that by holding the bars right next to the stem when standing on it.

    I've had this be the case once. I took the bar out of the stem, cleaned the interface of both really well, put a thin coat of grease on it, out it back together, and the noise went away.
