CFNex Ratchet Service Kit for CFNex Hubs

Engagement parts wear before anything else on a hub: the ratchet ring teeth, the little springs that push the pawls, and the seals that keep grit out. This kit is those parts, matched to CFNex hubs, so the freehub can be serviced at the kitchen table instead of shipped to a workshop.

What is in the box

• Ratchet ring in the tooth count you pick
• Spring set for the pawls
• Seals and the end cap hardware that comes apart during the service
• The fitting tool needed to put the ring back without bending a tooth

Picking the tooth count

More engagement points mean the drive picks up sooner out of a corner and the hub sounds louder while coasting; fewer points are quieter and drag a little less. 18T is the quiet, easy-coasting setting, 36T is the balanced one most riders land on, 54T is for riders who want the shortest possible pickup. None of them changes your cassette standard.

Before you order

Tell us which hub and which freehub standard you run, ideally with a photo of the ring coming off. Tooth count and spline are two separate choices and both have to be right, so we confirm the combination in writing before this ships.

Service interval

Rings and springs are wear parts. If engagement has started to feel rough, the freehub sounds gritty, or a pawl has stopped snapping back, that is the signal – do not wait for it to slip under load.

Lead time and shipping

In-stock kits leave the warehouse within 5 business days. Shipping is by FedEx, DHL or UPS, usually 5 to 10 days in transit. Orders delivered to the EU below the free-shipping threshold carry the flat customs handling fee from 1 November.
