Review: Perfect Replacement for Trek Freewheel - SunRace MFM300 Delivers! - After encountering a chain slip that left my Trek freewheel bent and malfunctioning, I was on the hunt for a reliable replacement. Installation was a breeze, and it seamlessly fit into my bike's drivetrain system. I appreciate how SunRace designed this freewheel to work flawlessly with OEM parts, ensuring a smooth and reliable shifting experience. I especially love the 14-34T range, which offers the perfect balance of gearing options for my cycling needs. Whether I'm tackling steep inclines or cruising at high speeds, the SunRace MFM300 allows me to find the right gear for any situation.
Review: Awesome Cassette! - These things tend to be hit or miss and often require a little research. The research I way heavily on is what other people are saying in their respective reviews. I had an incredibly bent rim and the old cassette was so seized I tried to take the bearings apart to remove it. A few dozen micro bbs went flying. Not only did this part get my bike in rideable shape, it saved the hassle of trying to rebuild the old one, was conveniently easy to install, it arrived overnight, and and and the gearing ratio is far superior than the old one! Just as everyone has commented your climbing will improve substantially!

### ⭐⭐⭐⭐⭐ Tough and reliable.
*by P***R on January 7, 2025*

I buy multiples of these in 7 and 8sp styles for refurbishing used bikes. Shimano compatible and cost effective. I recommend anti sieze paste or red grease for installation so it can be removed in a decade or 2 for replacement.
