How Things Work: Freehub Body

[Carbon_Dude]

Some good info on freehub bodies.  You can see why I think DT Swiss makes a good design, especially for the money.  However, if money was not an issue, Chris King hubs are truly amazing and I can see why they are so expensive.

Very good article. Thanks!

By the way, do you know why my DT Swiss rear hub lost its total silence?
Is it just grease? Do you put it often?

I would assume it just needs to be re-greased or have the correct grease.  DT Swiss makes special star ratchet grease that is a particular viscosity which gives the star ratchet just the right amount of sound.  Once I used Park Tools grease and the hub got very quiet.  If the freehub is very noisy I would assume that it's just dry and needs lubricant.

I have had a king hub a long time ago and i will never get another one.

It loosen up at the worst time and it required special tools. i sent it back to king for review and they found no issues with it.

I got rid of it.

But i had a hugi hub (the same star ratchet and it predated the dt swiss) i beat the crap out of it for several years with no maintenance. the star ratchet finally gave way. I was happy with the number of miles i had on my hugi.

When i rebuilt my 350 hub a year ago i put 70w-90 redline gear lube (probably any high quality gear lube will be fine)

But with grease it is sometimes slows down the engagement  and the teeth will not fully engage and could cause the teeth to strip out.
