Review on 🚲 SHIMANO Unisex FDM313X6 Bike Parts: Ultimate Performance Upgrade for Bikers by Anthony Lopez

I had shifting problems on my old Nishiki MTB with a 1997 Axera X derailleur. I couldn't find an exact replacement so I settled on this Altus. It's meant to be omnidirectional to pull the cable from either the top or bottom. While this is true, it is much better suited to downwash. When I put it on top bars, the cable now hangs outside the down tube and could potentially get caught on the trail. Note that I used a crimp connector to protect the end of the cable since I didn't have end caps on the ends of the wires. Installing this switch will require you to break the chain. So if your chain doesn't come with a master link, you'll also need to buy a chain breaker, and while you're at it you can replace your chain as well. Aside from these issues, my bike now shifts properly and it was easy to adjust the shackles and cable tension to get the correct indexing.
