Cyclists looking to shave weight without sacrificing strength, these titanium derailleur bolts are legit! Made from TC4 titanium alloy, they're incredibly lightweight yet strong enough to handle the demands of shifting. The M5×14.2mm size fits most rear derailleur jockey wheels perfectly. You get two bolts in your choice of gold or rainbow finish - both look seriously sharp on your bike. The full CNC machining means precise threads that install smoothly without cross-threading. The #3 Torx head provides good grip for installation without stripping. At just 7.3mm head diameter, they fit neatly in tight derailleur spaces. The titanium construction won't rust, so these hold up through rain, mud, and whatever else your rides throw at them. The weight savings might seem small, but every gram counts when you're trying to optimize your bike's performance. The quality is professional-grade - the threads are clean, the finish is even, and they feel substantial despite being lightweight. Whether you're building up a dream bike or just want to replace worn factory bolts, these deliver that premium upgrade feel. Installation is straightforward if you're comfortable working on your derailleur. Your bike mechanic will probably compliment your choice too! Definitely a smart upgrade for serious riders.
