Incredible upgrade – instant engagement!
I installed this on my Synthesis hub and the difference is night and day. The 6.6° engagement is so quick, no more dead zone when pedaling. The installation was straightforward with the included instructions. Totally worth the price.

Noticeable improvement, but not cheap
This kit definitely makes the hub feel more responsive and the sound is crisper. I had to wait for a good deal to justify it, but I'm glad I got it. The springs are a bit fiddly to install, but manageable.

Decent, but not the massive change I expected
I noticed a slight improvement in engagement, but it's not as dramatic as some reviews claim. Maybe my original hub was already quite good. Still, it's a quality product and I appreciate the faster response.

Perfect for my Synthesis wheels
Received this kit quickly and it fit my hub perfectly. The ratchet ring is hardened steel and the springs are robust. The 54 teeth give that satisfying rapid click when coasting. Excellent upgrade.

Works as advertised, but a bit pricey
The engagement is definitely faster, almost instant. Installation took some patience but the outcome is worth it. I wish it were cheaper, but it's still a solid investment for my bike.
