Cyclists, these FLEXMAN quick release skewers will make your life so much easier when you need to remove your wheels! The front skewer measures 135mm (about 5.31 inches) and the rear is 170mm (about 6.69 inches) - fits pretty much 99% of mountain bikes out there. Made from aluminum alloy with steel components, so they're lightweight but seriously strong. The quick release lever makes removing and installing wheels a breeze - no tools needed, just flip the lever and you're done. Perfect for when you need to transport your bike in a car, change a flat tire quickly, or do maintenance work. The detachable design means you can remove the lever entirely if you're worried about it catching on something during aggressive riding. Comes in two color options so you can match your bike's aesthetic. The construction feels solid - not cheap or flimsy like some no-name skewers that can bend under pressure. Seriously, if you're tired of fumbling with tools every time you need to take your wheels off, these quick release skewers are worth every penny. They install in minutes and make wheel removal so much faster than dealing with bolt-on axles. Your bike maintenance and transportation will become way more convenient with these installed. The universal fit means they'll work with most mountain bikes regardless of brand or model year.
