Loctite Threadlocker Blue 242

Why I Use It

A tiny dab of Loctite Blue 242 can save your ride—and your sanity. I keep a tube in my toolbox for anything that has a tendency to rattle loose over time: brake rotor bolts, bottle cage screws, cleat bolts, and even suspension hardware if needed. It’s the go-to medium-strength threadlocker that keeps things secure but still serviceable.

For race setups especially, it’s peace of mind. Apply it once, and you’re not second-guessing whether your brake adapter bolts will start backing out mid-descent. If you’re regularly swapping parts or fine-tuning setups, Blue 242 is strong enough to hold without requiring heat or heroic effort to break free.

Pro Tips

• Don’t overtighten. Use a torque wrench and let the threadlocker do its job.
• One drop goes a long way.
• One tube lasts forever. You won’t need to restock often—unless your riding buddies start borrowing it.
