Freehub damage - what can be done apart from replace
Postby SmellyTofu » Sat Jul 26, 2014 9:31 pm
Basically looks like this.
Apart from replacing it (which it'd dig another groove in a brand new freehub), what can be done to stop of getting worse.

I believe this was the reason behind the deeper splines on the first generation of 10 speed they brought out. Eventually they bowed to the pressure of keeping backwards compatibility and reverted to the shallow splines.
Aftermarket brands don't care so much and are happy to have a wheel/hub with a lighter weight, as well as sell you another freewheel body when this happens.
If your wheel/hub manufacturer makes a steel or ti freewheel body then opt for that.

Great tip. I might need to go to Tiagras before they get even worse. (Btw, my question was in regards to Zipp freehubs).harmonix1234 wrote:I use tiagra cassettes for this very reason. 8 of the 10 sprockets are on the spider. Only the two smallest sprockets aren't attached. I went through two freehubs in one year on my ZIPPs with my high end sram cassette. Got jack of it and went tiagra. Shifts really well, lasts really well, but the tradeoff is that they are heavy. But hey, who cares about a few grams to get better performance and longeveity from your components. Don't have that problem any more. Try one out.

Agree Tiagra is one of cycling's best kept secrets. I started out with a full Tiagra flat bar from 2008 and to this day, no maintenance apart from some occasional wiping and lube, it was super reliable and shifted very cleanly across gears.

aside from that, torque it up right (but I doubt that helps much) its not really an issue until it eats all the way through.
whats the torque on the rattle gun? I'd be more worries about breaking the threads.

All Shimano hubs come with either steel or Ti hubs and don't have this problem.
I bought a Hope Pro2 EVO hub that came with an alloy hub, but knowing this issue up front I simply ordered the steel freehub and swapped it over. The weight difference is insignificant.

American Classic installed a sliver of steel on the edge of one spline to stop this happening.

I have Hope Pro Mono RS rear hub and will likely upgrade to steel freehub in the future.queequeg wrote: I bought a Hope Pro2 EVO hub that came with an alloy hub, but knowing this issue up front I simply ordered the steel freehub and swapped it over. The weight difference is insignificant.
They're about an extra 100g?

I didn't weigh them both, but I am happy to put both freehubs on the scales tonight and give a definitive answer.Rex wrote:I have Hope Pro Mono RS rear hub and will likely upgrade to steel freehub in the future.queequeg wrote: I bought a Hope Pro2 EVO hub that came with an alloy hub, but knowing this issue up front I simply ordered the steel freehub and swapped it over.

Hope Pro 2 EVO Alloy Hub (with bearings, spacer & seal) - 86gRex wrote:That would be great, cheers
Hope Pro 2 EVO Steel Hub (with bearings, spacer & seal) - 166g
Difference of 80g, which I would say is insignificant. Empty 80ml of water from your bidon if you want the extra 80g back when using the steel hub

I have a Novatec one that I picked up from here, but I imagine there are others like it:

Hey JBark,JBark wrote:Similar to the steel clips posted earlier, some hub makers offer alloy hubs that have a single steel spline. I picked one of these up when my original freehub failed, and it does what it says. Still a few small marks on the other splines, but nothing compared to the original all alloy hub.

Just wondering if you have a Novotec branded wheel or you have some other brand name? I have a Specialized Roval wheel (2012 EL45) with a free hub that looks the same as the one in your photo. I want to convert it to 11 speed, and it has some damage as the OP had on the old 10 speed, so may get the steel spline version. There are several types of this style of freehub from Novotec (A,B,C,D etc), and I don't know how to determine which type were used by Roval. Just wondering if you have any idea how to work that out?
Cheers,
Adrian
