Rounding out a bolt on your bike is never a good thing, whether it’s through being seized or by accident. Both pedal cleat and disc rotor bolts are particularly susceptible to getting stuck or rounded out so this guide will run you through how to safely extract them without damaging anything expensive. The first thing to say – and one that won’t much come as much use if you’ve already gone and rounded a bolt out or found one that’s stuck solid – is that prevention is much easier than the cure. That means using an anti-seize compound on things like cleat bolts and pedal threads. You can also use blue Loctite on disc rotor bolts – you don’t want any grease near them – as it acts to prevent corrosion as well as stopping them coming loose. It also goes without saying that you shouldn’t overtighten any bolt in the first place. Make sure that you use high-quality tools. While it’s possible to do pretty much anything with a multi-tool if you have to, using decent hex and Torx keys or bits will reduce the chances of the bit slipping out and doing damage. You’ll also be able to apply much more torque to a fastener if...
