Just installed these titanium bolts on my mountain bike's hydraulic disc brakes, and wow – the difference is noticeable! The weight savings might seem trivial (we're talking grams here), but when you're grinding up steep trails, every ounce counts. These bolts replaced my stock steel ones, and the bike feels snappier during quick maneuvers.

The machining quality is impressive. Threads glide in smoothly without cross-threading, and the hex head sits flush with the caliper. No more scratched knuckles from protruding bolt heads! I've ridden through muddy singletracks and river crossings for two months now, and zero corrosion – titanium's corrosion resistance is no joke.

One minor gripe: The package didn't include thread locker. I had to use my own blue Loctite to prevent loosening from vibrations. Also, double-check your caliper threading – these ONLY work with threaded hydraulic systems, not post-mount or mechanical disc brakes.

At $25 for a set of four, they're pricier than generic hardware store bolts, but for weight weenies or riders in wet/salty environments, these are a smart investment. That 'Worked perfectly' reviewer wasn't exaggerating – these deliver pro-level performance for weekend warriors.
