Bias is totally okay! But trying out the D684 might surprise you. You never know until you try!
It’s great to have loyalty to your gear! If you ever get curious enough, a test ride could be fun!
Can we talk about the aesthetics? The D684 looks way cooler than the D965! 😂 Does that even matter when you’re shredding?
Aesthetics can be subjective, but it’s true that we all love a good looking bike part!
Haha, totally! But I think performance beats looks when you’re tearing down a hill. Still, nice to have a sleek look! 😎
Stoked to see a comparison! I’ve always liked my Yeti but I keep hearing about how good the Pilo D684 is. Anyone made the switch?
Switched and never looked back! The ride quality improved significantly for me, especially on steep climbs.
Welcome, Ben! Many riders have made the switch and have shared positive feedback. It might be worth considering!
I love my Juliana, and the Pilo D684 has been a lifesaver! But I do worry about durability. Anyone had issues?
Same here! I’ve put mine through some rough rides and it’s held up pretty well! 🤙
Durability is always a concern! Most users report good experiences with the D684, but it’s good to keep an eye on wear and tear.
I’ve tried both the Pilo D684 and the D965 derailleur hangers. Honestly, both are solid, but I feel like the D684 has a slight edge when it comes to my Santa Cruz Tallboy. Anyone else feel the same? 🤔
Thanks for sharing, Jason! It’s interesting to hear about your experience with the Tallboy. Have you noticed any specific improvements in performance?
Totally agree with you! The D684 seems to handle everything I throw at it, while my buddy’s Yeti doesn’t seem as responsive. Maybe it’s just my luck? 🤷♀️
