    Clicking noise coming from Mercier Kilo TT.

    So I rode 80 miles on my Mercier Kilo TT on Saturday & I noticed I started hearing a rythmic clicking noise towards the end of my ride coming from the drive train. Does anyone have any idea what that might be? It seams to only occur when I'm applying a lot of force to the pedals. When I tried lifting the bike up and spinning the pedals closer to my ear, I couldn't hear anything.

    It's likely the interface between the pedal and the crank arm. Remove the pedals, grease up the threads, and reinstall. If that doesn't help, it may be a bottom bracket interface issue. Remove the bottom bracket, grease the threads, and reinstall.

    Thanks for the help shants! It sounds easy enough to do all of that myself, but what tools will I need to remove the bottom bracket?

    Check the chainring bolts too.

    if its your cranks/chainring be careful and tighten before you keep riding them. you can ruin the square taper of the crank arms if ridden while loose.

    Kilo TT doesn't have a square-taper BB unless the stock BB has been changed out. The stock BB on the Kilo TT is splined ISIS.

    EDIT: But I'm not discounting the advice about making sure they're tight.

    It's actually not ISIS although it looks like it. It's a propietary format from Truvativ called PowerSpline.

    An ISIS crank puller won't work. You have to use the normal square taper style crank puller although it looks* like ISIS.

    To the OP, try tightening the cranks and chain ring as already mentioned. If that doesn't fix it, the Truvativ Touro crank/BB that the bike comes with isn't all that special and you may have to replace it. Some people get a few months out of them, some 2 years, it just depends. I upgraded to the Truvativ Omnium.

    You're right. My bad; I couldn't remember the name and ISIS popped into my head.

    I tend to run $20 dollar pedals and just change them out, instead of 'investing' in something nice. Anyway, they come with cheap, loose ball bearings, and when they start clicking I know it's time to replace them. So how nice are the peals on that bike anyway? You might be able to lube and adjust them. Or if they're low spec you might consider changing them out.

    Thanks for all of the advice guys. I took a look at it tonight when I got home from work. I removed the pedals, cleaned the threads & replaced them--they're the MKS Sylvans BTW. I then checked all of the bolts on the chainring & one of them is loose. It looks like I'll have to pick up the tool to hold the backs of the bolts tomorrow. No way around forking out for the bull****e tool I'm assuming?

    just buy the tool. I did -- 20 years ago and have used it many times. Think of tools as a long term investment.

    Yeah, I'm going to pick up the tool today. Out of curiosity, if I were to eventually upgrade my crankset, could I get Suginos if I were to upgrade the bottom bracket along with the cranks?
