New pedals

So I needed new pedals again. Pesky things keep wearing out.  The first lot I had lasted ten years, according to this, but these one only lasted five. Perhaps I’m doing more kilometers on this bike than I was. Anyway, I bought some more, and got out my pedal wrench to fit them.

However, I hit a snag. I couldn’t get them off. They were stuck tight. I tried all sorts of things, different spanners, cheater bars, blocks of wood – but they would not budge. I even managed to break a fancy chrome-vanadium spanner in the attempt. I took the cranks off, and got the guys in the machine shop at work to have a crack at it with their array of professional vices, jigs and tools, but to no avail.

Oh dear. It seemed like I was going to have to replace the cranks as well. I looked at various options for crank replacements, but nothing seemed very easy. In the meantime, my feet were slopping around in the pedals like sloppy things.

Then, on they way to work, I popped into the bike shop. You might be thinking that I should probably have done this in the beginning. And you would be right. Using whatever secret bicycle shop techniques they have they managed to get the old pedals off, and put new ones on. Slightly fancier ones, to boot. They did wryly say ‘it was a bit tricky’. Anyway, kudos to the guys at Park Bikes. I am now set for another five or ten years…

  1. Two “tricks” for pedals:

    Releasing a stuck steel bolt inside a aluminium thread you heat up the part and the aluminium expands more than the steel loosening it off. Heat gun or blowtorch are good but a hairdryer works too. Resorting to impact or shock loading can be damaging to the parts.

    When assembling the pedals back on, always use thread locker or anti-seize compound to prevent it happening again.

    • Great tips.

      That said, my personal tip would be that if the pedals don’t come off easily straight away, go to the bike shop so they can do bike shop voodoo on them…!
