Hub vs Hub body

The pawls inside the free hub body of the rear wheel became corroded and seized up - on my less-than-a-year-old mountain bike. I am a novice, and I am trying to figure out what to do. Do I replace just the hub body or do I replace the entire hub?

I understand if I replace the hub, the wheel has to be rebuilt. If the wheel is rebuilt, I have to buy new spokes as well, correct?

What Hub?
A brand & model number would be useful to know for sure if you have a free hub or free wheel.
If the latter, you just replace the free wheel.

Do you leave your bike in the rain?

Thanks for your response! All I know is that the hub reads: SPEED TUNED WHEELS. ?

I am not sure I understand the difference between free hub, freewheel, and freehub body. I found the following explanation on the internet and I think I understand this, but your question regarding freewheel/freehub confused me.

"The hub is the body at the center of the wheel containing the axle. It is more or less just some bearings in a pair of cups that rotate around the axle. The freewheel is the mechanism that locks when pedaling forward (forcing the wheel to be driven by the chain) and spins freely when coasting or pedaling backward. On most modern bikes with multiple gears, the freewheel is built into the rear hub and the whole assembly is called a free hub."

Anyway, I took the wheel to a bike mechanic because I didn't have the tool to remove what he called the free hub body (the piece that protrudes out from the wheel - that the cassette is installed onto). He opened it up, the pawls were corroded, he cleaned them up, replaced it but said he wouldn't trust it and i had to agree. So, he gave me the impression that I needed to replace the hub and have the wheel rebuilt. I have contacted the shop where I bought the bike and they suggested a part for me to buy to fix the problem and it is just the free hub body.

So, I am confused about when the pawls fail, as they did on my bike, does the free hub body only require replacement or does the whole free hub require replacement.

Thank you so much for your help.

PS: No, I don't leave my bike in the rain, but I do ride in it, and the dirt, sand, mud, etc. It is a mountain bike.

Right!? Darth Lefty. The bike has <200 miles on it. I contacted the online shop I bought it from and they are claiming it is a maintenance issue. I argued that there was clearly an issue with grease at the factory, or seal or whatever. Who does maintenance on their hubs in the first year unless they ride it 1000 miles? They are willing, maybe to discount a new part, so, the question is whether I replace the hub or just the hub body. I think I want to upgrade the hub... Then, I ask, is it customary to upgrade both of them?

Speed Tuned Wheels is related to StaTru Wheels, as far as I can tell from an internet search.
Parts & Accessories

But, I'm not sure what model you have.

Rebuilding the hub (bearings, freehub, etc) should be easy enough to do.
Replacing the hub is a major pain. Spokes not only need to be installed, but they need to be tensioned and the wheel trued. If the new hub is the same size, you might be able to re-use the spokes, otherwise, all new spokes too.

I'd probably replace the freehub body, then if it only lasts another year, consider a better hub.

Replacing the whole hub would ask for undoing all the spokes, then lacing the rim for a new hub. Not sure of the quality of your rim, spokes (and the hub). It might be cheaper to get a cheap wheel (LBS near me has cheap decent wheels for about 20 euros), or get a Shimano Deore (or better) hub, DT swiss spokes and a decent quality rim, lace it all and build (or have it done by a LBS) yourself a good quality wheel that will last long time.

If you can get contact info for the people that make the wheels/hubs, you can deal with them directly and bypass the shop.


https://statruwheels.com/Contact-Us.html try using that.

Freehubs are not greased, they are oiled. Oil is far more easily washed out by water. The fact of having rusted pawls says there was water in the freehub body. Allowing water to get in and also doing something about it isn't determined by the manufacturer, it is in complete control of the rider. Rust doesn't care about mileage, it's dependent on opportunity and time. Like the car driver who claims his rear ending the car in front is someone else's fault this problem is the rider's responsibility. Any warranty that's offered will be to keep the rider happy, not because of any implied contract. Andy.

If it were me I would buy a shimano hub and rebuild the wheel. I did that for a friend before she and her husband did a 2500 mile tour. The reality is that the shimano hubs are the best on the market.

And if there is on the road repairs needed, they, Shimano, will be what small shops can fix easiest, as they Dominate the Market.

Me, I'm dodging the whole warranty question. Just focusing on the problem.

Replace the freehub. While it's apart service the hub replacing bearings and greasing everything. Go ride.
