Carbon Ti Cassette Body Damage

[Mr.Gib]

What do you guys think?
A few months old, maybe 1500km, 75 kg rider, a few cogs literally cut right though the splines. Shimano cassette of course.


How is Carbon Ti on warranty? Do they make a steel cassette body? Or should I go back to the builder Farsports?

Which cassette, how tight and what lubricant (if any)?

[kode54]

Looks like the loose cogs (17T) slipped. Odd that it only scored a few splines. Is that a Campy freehub?

[TribesMan]

Splines on Campagnolo freehub are much deeper...

[Cubist]

Cassette not tight enough!

[alcatraz]

Either always use a torque wrench on the lockring (cleaned + greased threads), or swap to a unibody cassette like sram red and others. Those cassettes completely eliminate spline chewing on soft freehubs.

To be honest, I am not sure that can fall under warranty claim, quite directly linked to improper lockring-torquing (having lubrication in between the cogs will also be an aggravating factor since it facilitate the cogs to slips between each other).
One alternative if you don’t want to replace the body is to use monobloc cassette (Edco, Sram...) that do not use the section damaged.
