• Will grab a picture of the front chainring tomorrow, thanks both for the input! How do I check for stiff links? I could try running it free for a bit (reluctantly) but I can’t replicate the issue even if it’s fixed, and it’s occurred about once every two weeks or so with daily commutes to multiple places?

    The cranks definitely did lock up momentarily, hence coming unclipped each time, but given it’s fixed presumably that would have happened regardless of whether it’s the wheel or the chainring locking up?

  • What is the chain line like I. E. If it is a conversion have they got a decent chain line with the rear cog in line with the front?
    Or is a small stone/chip getting stuck on the tyre and carrying around to get jammed under the mudguard and/or brake caliper?
    Given the decent weather why not run it without the mudguards and see if that helps.
