The Silver Hubs

[Ginz]

What do y'all think of the new Silver hubs?  Are they cartridge bearing'd?  It looks that way in the photo but I'm not certain.

I've been thinking of building up a rear mtb wheel for the Hunq using Shimano XT.  This would be better, I think.

[Chris Lampe 2]

I was wondering the same thing about the bearings.  A few years ago I had Rich build me a set of 700c wheels and he described the hubs as "no brand" but made by a Taiwanese company that he ID'd by two or three letters.  I'm betting they are from the same company as the Silver hubs.  Mine are definately cartridge bearing and you can see the seals of the cartridges.  So far, they have been flawless and still spin like a brand new set.

Novatec, probably.

Yup, looks very similar to these, but in the nicer silver color!

Good Luck!

Yeah I spent a lot of time looking at pictures of the hubs...They definitely look like cartridge hubs, since I don't see any cup and cone wrench flanges... :)

     FWIW .... If you look very closely at the distinct perpendicular markings on the freehub body of the Riv, it does not match either Novatec or KT . 

The Riv hub CS body appears alloy , please tell me it is not !

Really though, for any true info , you gotta call Riv as the website doesn't say much , and the truth is in the details .

[Christopher Murray]

Grant said they are made by KT. I believe this is in the Blug.

Cheers!
Chris

[jpp]

It says kt in discription on the website

[Roger]

Visually, the website picture of the rear hub seems identical to the hubs sold at last year's garage sale (except for the whimsical can't-spell-stuff-good new logo). The front is a different design.

[Evan Baird]

Are these the same hubs that Velocity sells on their road wheelsets?

[carne...@bellsouth.net]

Road hubs: QL-ZL7R look the closest - 6 pawls, etc. , just not enough holes in the flanges.
I have ordered a set of the Silver from Rivendell.

[Garth]

 David,  When you get them can you please post if the CS body is steel or aluminum ?

[J-Perp]

Aluminum according to Kevin.

[Jim Bronson]

Is this cr-mo freehub body interchangeable?

Keep the metal side up and the rubber side down!

[carne...@bellsouth.net]

This would be a 6 pawl: http://o-lite.com.tw/news.php?m=d&id=16&p=1
I called Riv and talked with Rich. I was mainly asking about the availability of the 130 end caps, but also asked if the body was steel or aluminum. He first said aluminum, but after checking said steel.
David

[Garth]

    I'll take Rich's word for it as he actually handles them .  Thank you David for asking ! 

[Rich Lesnik]

Another interesting characteristic of the rear hub is the location of the pawls. Unlike "most" freehubs, which have the pawls on the freehub body, these hubs have the pawls (6 sets of 2ea) located in the hub body, with the ratchet ring on the freehub body. So the "moving parts" move less -- great design. As for the steel-or-alloy freehub body, my money's on steel. I'll check it with a magnet when I'm back there on Thursday. Oh, and yes, definitely cartridge bearings. 4 in the rear hub.

[Rich Lesnik]

Well, bad on me! We checked the freehub body at Riv today, and, while the spacer and bearings are indeed steel, the freehub body itself is alloy. Sorry. Still a great hub, though.

[Ginz]

So, does anyone think they can wear out the alloy freehub body? :)

[Bill Lindsay]

The prevailing worry is your cassette cogs will dig into the splines and make it difficult to remove your cassette down the line.  It's a pretty common thing for riders like us to just say "enough, I'm never buying an alloy cassette body again".  It's one of the reasons many of us think Deore XT from the late 90's early 00's were so great.  So many of them that they are really cheap.  Still made in Japan so they were good quality.  Steel axles and steel driveshells so your gears come off easy, no matter what you do.  The only acceptable lightweight alternative for many is Ti (white industries, Dura Ace).  

If Rich says they are nice then I trust they are nice, but many in this group will hear alloy drive shell and will steer clear.  It's a fact. I'd probably give them a shot, but if Riv had asked me to spec their Silver rear hub, I would have advised a steel driveshell for this reason.  One less thing to have to talk about.  The gram savings mean nothing in the context of a Rivendell.  Maybe this particular alloy driveshell is "just as rugged", or close enough, but maybe it's not.  Steel would not have been less rugged, and would have been heavier.  The handwringers will wring hands more over alloy than they would have over the heavier weight.  

[Jim Bronson]

Question is, can a steel replacement be obtained?  A prior post pointed out a 6 pawl cro-mo freehub from the same manufacturer, is it a direct fit?

I had never heard of an alloy cassette body before.  I was completely surprised to read that the Silver hubs have this.  I didn't know that this was a thing that hub manufacturers would do.  Considering the cogs are steel, and all the motive force propelling the bicycle forward is transmitted through the driveshell, aluminum does seem an unlikely choice.  I would have thought it would be way too much stress for aluminum.  It would seem a no-brainer for Riv to have spec'd the best of all possible bike materials, i.e., steel for the job.  I wonder what their reasoning was.     

[carne...@bellsouth.net]

My hubs arrived yesterday. They look at least as good "in person" as in the photos. The alloy vs steel question has already been answered. I plan to take the recommended precautions, but that is not a deal-breaker for me. I hope that issue does not make them go away. As others have said, if Rivendell sells them I am willing to use them.
I could not resist dismantling them part way before passing them on to the wheel builder. One thing I learned is that you need at least one 10 mm. hex wrench in addition to the two fives.
David

[Ginz]

Have any folks been riding their new Silver hubs?  Any thoughts?

I'm considering one for a rear, heavy duty touring and trail wheel.

[Lungimsam]

Wonder how they compare in weight and functionality to the Deore hubs

[George Schick]

Anyone know if these were ever offered in 130mm rear spacing?  I see at least one remark in this thread about checking with Riv "about the availability of 130 end caps."  Are they available?

[carne...@bellsouth.net]

Rich said I would receive an email when/if the 130 end caps were available. None yet. He also said he felt it would be no problem if I squeezed them into my 130 spaced Riv Road. Was easier than I expected. I have had my new wheels with these hubs for about a week with limited riding opportunities, maybe 20 miles so far, so not much to report. Thought I would pull the cassette and check the hub body around the end of the year. I did remove the body and put a ring of Phil grease on the pawls. I don't hear as well as I once did, but to my ears they are virtually silent.

Hi, does anyone know the answer to Jim's question, below, re: replacing the alloy freehub body with a cro-mo one on Silver hubs? I removed my cassette last night with great difficulty to discover rather large grooves in the splines cut by the cassette. Grateful for any advice.

[Jeremy Till]

I've been researching the possibility of getting a cromo freehub body for Silver hubs and haven't actually come up with a solution but do have a couple of leads: 

1. After some sleuthing I have come to believe that the Silver hubs were manufactured by KT, a Taiwanese company that manufacturers hubs for a number of other brands, and whose website used to show a cromoly replacement freehub with the same mechanism as the Silver ones.  I emailed them about the possibility of getting one in the U.S. and was directed to HiFi wheels, a boutique wheel builder in Portland whom I assume is a North American agent for KT.  They don't list the freehub bodies on their website, and they never responded to my email inquiry.  You may have better luck--let us know if you do!  

http://ridehifi.com/

 

2. I have recently discovered that the SRAM S40/60/80 wheels seem to have used a KT hub with the same freehub mechanism, and that there is a replacement freehub body out there that looks like the Silver one and is listed as being steel: 

https://www.benscycle.com/sram-s406080-910-speed-freehub-body-and-seal/freehub_body_sram_freehub_bodies_8116_fw4553/product

(It's listed in the QBP catalog and thus is available from a number of vendors, this is just the first one that showed the material).  Buying this was going to be my next attempt (haven't do so yet), but I will say that I have no idea if it is actually going to work on a Silver hub and if it is indeed steel. If you buy one, let us know how it works out!

[Bill Lindsay]

I looked at that Ben's Cycle listing for a SRAM freehub.  I'd bet a dollar that IF it's really gold in color, like that picture, that it is not in fact steel.  I don't know of a way to make steel be that color.  That's a picture of an aluminum freehub body.  If the item you are actually buying looks alot different from the photo, then maybe it's steel.  They might be referring to the drivering itself, with the ratchet splines, which most certainly is steel.

[Montgomery Engel]

I think that’s probably right. I contacted Rivendell and they do not have and did not know of any cromo replacements. I think there are more alloy freehub bodies out there that are compatible, but I think I’m just going to ride this freehub into the ground, i.e., until I can’t get the cassettes off or I have to rebuild the wheel and then decide whether to chance it with another alloy body or get another hub. I sort of doubt KT is going to be making a cromo replacement.

It seems to me this is an engineering error. The softer alloy splines are the same depth as the harder cromo splines in the Shimamo compatible bodies. It strikes me that they should have increased their depth to compensate for the weaker metal. Instead, no surprise, it seems like their answer was to use pricier, interlocking cassettes that are probably less likely to cut the splines, but I’d so much rather have a bulletproof but heavier freehub body and keep using reasonably priced cassettes that I think probably wear at similar rates to the cheap ones!

Thanks for the thoughts on this.

Some aluminum freehubs put a small steel strip on the load bearing part of the gear mating profile. Seems like a good idea.

Eric

[Jim Bronson]

Rich just sold 4 Silver hubs with the steel freehub body on a first come first serve basis.

I am one of the lucky recipients :)

Next time the wheel is rebuilt on my Road Standard (which happens every 2-3 years as I destroy rims with some regularity) it will be with a Silver hub!
