About Rival hubs

Hi there,

You can chek on my post on mtbr and you will see Front and Rear hubs.

Sorry for the "holy thread resurrection" but I thought I'd update this thread with info, for people who might come to it via search engines.

I have a set (KFS500C/KRS500C CARBON hubs) on the way right now. I learned my lesson with proprietary hubs from the past, though, and ordered an extra freehub body with the deal. I worked with the person who posted this auction...

http://cgi.ebay.com/Rival-KFS500C-K...Cycling_Parts_Accessories?hash=item41494c10ab

...and she was super helpful, even providing a photo of the freehub body separated from the hub to see the interface. There are other color options as well - mine are coming in solver and will be mated to a set of Mavic XM 719 silver rims. I'm still a rim brake guy, running Magura HS33's. The wheels will replace a set of XTR M952/Mavic 517's on my newly restored Proflex 956LE...yeah, it's old, but it rides very well and looks brand new!

More info to come...

Hello all,

Now that I have my hubs I just wanted to post a follow up...I must say that I'm very impressed with them so far. The flanges are perfectly true and even and all the machining touches I'd expect are there (nicely chamferred spoke holes, etc.).

The seller, Eva, even sent me an engineering diagram for the rear hub...she's just about the best eBay seller I've ever dealt with, and that's with the goods coming all the way from China.

Front:
There are two o-ringed end caps...these provide the interface to the fork drop-outs (mine are QR hubs front and back)...the axle itself is completely inside, the ends of which interface with recesses in the back of the end caps. With the end caps in place you essentially have the o-ring on the cap sealing out the elements, and the bearing is sealed, of course, too. Even with the bearing seal and o-rings the hub spins easily and is buttery smooth (and Pittsburghers know butter).

Rear:
This one I'm still figuring out, as I haven't had it all apart yet, but it appears that the axle has one fixed end (drive side) and is fed in from the drive side, through all the bearings, and then through the end cap on the non-drive side (which is locked in place by a 2mm Allen head grub screw). The freehub body sorta resembles the Easton type, where the body has one main piece, with at least one bearing inside to ride on the axle, and with 3 pawls at the base that fit inside the hub body. The pawls make a nice click...louder than my XTR M950 hubs, but not quite as loud as my Spinergy Xyclones. Extra freehub body was $25.

Mine are silver and appear to be clear anodized, as it doesn't appear to be bare alloy. I tried to twist the flanges in opposite directions to test whatever they used to mate the carbon middle tube and it didn't budge. The skewers are nice, though I'll probably replace them with a set of ControlTech skewers I have when it comes time to mount the finished wheels on the bike.

I'll be mating these hubs to a set of rim brake Mavic XM 719's (in silver), with Wheelsmith DB14 spokes and brass nipples, and will let you know my impression when I'm able to ride 'em.

Just FYI...

- Doug

The Rival's are made by Novatech, which is the high-end division of mega-hub maker Joy Tech.

I ended up going with the Novatech's- The front has been pretty bulletproof, the rear I blew the freewheel out of on Zippity Do Da after about 600 miles.

I'm 205, got almost 5000 OFF ROAD, hard core miles on my 07 anthem, and I am extremely hard on equipment, (3rd front triangle, 3rd rear triangle, 7th bearing set, etc...)so I would say if you're an average rider or 180 or less, these hubs would be fine- they're cheap, light, they look awesome, and for most riders would probably be ok.

I'd use them on a build for my wife in a heartbeat, but she likes the Hopes. I switched to a Hope rear after the blow out and haven't had a problem since.

Novatech replacement freehub bodies are widely available from many dealers, QBP stocks them as I recall. They're about $25 each.
