Crankset clicking - Evosid - where to start?

(1/3) > >>

lantz:
So, I thought I had this resolved, and I've made some progress, but I've got a 1x Evosid crankset on a new gravel build and it's functionally almost perfect, the *one* issue is that when I put power into the pedals there's a.. almost tensioned-feeling.. creak/click. Some observations as I've worked on it:

- I feel it through my pedals and into my shoe.
- It's almost exclusively left side, but I have observed it on the right side.
- It's specifically at the.. call it 10 o'clock stroke of the left pedal when the power is being exerted *forward* and down.
- It almost feels like it clicks forward, then releases back when I lay off the pedal or pedal backwards.
- It's not regular, and takes quite a bit of power (think a 230lb dude going up a 5% grade and increasing cadence)
- But when it happens, it happens consistently.

I've tightened the crankarms down, without having a 50+nm torquewrench, I don't want to overtighten, but I have a feeling it's just a matter of getting those threads snug?

I've pulled the BB out, checked the bearings, listened for any indicator there, and nothing doing there.

My hunch is it's in the interface of the internal crankarm and the spindle - anyone seen/solved something like this before?

Does it happen on all cogs or only in the climbing low gear? If it's all cogs, it could be a BB/crankset issue, if it's only in climbing gears it could be something else.

I'd double check your pedals if they're secure. Check the freehub if it's well greased and/or check if creaking happens only on-saddle which could indicate the seat post needing carbon paste or tape to reduce any micro movements. Also check if your saddle needs carbon paste as well.

I was having similar issues, but only in climbing gears. I figured it was related to my seat post after taking apart my BB and crankset.

Yeah, all cogs.

Should have specificed, not a pedal issue - 3 different pedals with 2 different cleat sets (crankbros, spd and flats) and I can get it to creak by applying force directly to the crankarm while standing alongside the bike, so not the seatpost, seat or pedals.

Is your chainring bolts torqued to 8nm? I'm guessing the EVOSID is a 3 bolt style crankset. Also try rocking the crankset back-n-forth in the BB to see if there's any minor play. Even if you think the crank is secure, it might not be fully locked in. If that doesn't work, I'd try another crankset (preferably with a steel axle) to see if it still creaks. If it does even after swapping out, it could be the BB not being secure or needing extra grease.

It could also be that you weigh too much for your crankset!  ;D

In that case, I'd just go find a 1x GRX crank and call it a day!
