If you ride DMR V12 V2 pedals on your mountain bike, this service kit is essential maintenance gear to keep them spinning smoothly season after season! The kit includes everything you need to rebuild those pedals when they start getting gritty or developing play: 2 sealed bearings, 2 bushings, both regular and reverse threaded nuts (because bike pedals have opposite threads on each side - clever, right?), 2 end caps, 2 internal rubber seals, and 2 external shields. It's basically a complete refresh for your pedals' internals. If you're noticing your pedals aren't spinning as freely as they used to, or there's side-to-side play, this kit will have them feeling like new again. The installation does require some specific tools and mechanical know-how - you'll need pedal wrenches, bearing press tools, and some patience working with those reverse threads. But if you're comfortable with bike maintenance, it's a straightforward job that'll save you the cost of buying brand new pedals. These DMR V12s are such popular pedals among mountain bikers for their great grip and durability, so it makes total sense to maintain them properly rather than replacing them. Keep a kit on hand for when your pedals need some love, or grab one preemptively if you know you've put some serious miles on your current set. Your feet (and your wallet) will thank you!
