I picked up some new MKS Sylvans a couple of weeks ago. Everything was fine and dandy, but lately I’ve been getting a weird popping in the left pedal.
Basically, on one point of the rotation, the pedal pops outwards slightly, as if a bearing is skipping or something. They’re all tightened up, and I’ve had a play and can’t feel any movement in them. It doesn’t happen all the time, but it’s more constant now.
Anyone else had a similar problem? It’s happened to me with older pedals as well, but I figured there shouldn’t be a problem with something new. It’s getting pretty annoying!
I had a similar problem, but with different pedals. Turned out it was the bottom bracket: The lockring was loose, enough so that the adjustable cup was able to move very slightly. This felt like the left pedal was moving in and out - but only when pedalling really hard at low revs.
Maybe check that your BB is tight and that your crank bolts are done up?
That sounds possible, because the pedal action really seems fine. I just tightened up the crank bolt on the left side and it was a bit loose. Let’s hope that was it! Cheers!
