Reynolds freehub body swap

Reynolds have used a variety of hubs for their wheels – at one point they were made by Hadley, then White Industries, then a cheap Chinese hub, and now a combination of DT Swiss and the no-name Chinese.

This particular hub was made by Hadley in the USA – I’m not 100% sure on the dates these hubs were used but they’re fairly rare and swapping from the Campagnolo body to Shimano was proving difficult for their owner.

It took a bit of time but after contacting me I managed to find a used freehub body at one of my suppliers in the USA and I had it shipped over with an order.

As is the case with a lot of hubs the Shimano and Campy versions are dished differently.  Back-in-the-day there would have been a Shimano endcap for this hub to accomidate this different dish but no such luck with the used freehub body so I made a 2.5mm spacer on the lathe to sit between the endcap and bearing preload adjuster.  You can see the thin silver ring in the photo of the non-driveside of the hub.

After re-dishing and truing the wheels it’s now on it’s way back to Masterton for some racing.

American Classic freehub body swap

Swapping the freehub body on an American Classic rear hub from Campagnolo to Shimano.  Removing the freehub body exposes the unique 6-pawl design of the hub and the clutch plate which engages the pawls.  Unlike all other brands of hub the pawls in an AM Classic are not actually responsible for the ratchet mechanism – a small steel spring rotates across the clutch plate which causes the ratcheting sound….when the hub is engaged the clutch plate brings the 6 pawls into contact with the freehub body.  Cleaning the hub is crucial to having it perform well.

The wheel needs to be re-dished between Shimano and Campagnolo freehubs.

I do a lot of repair and maintenance work on all brands of wheels for people all around the country – please contact me if you need speciality work done.
