Cantilever/V-Brakes used on Disc Rims

I recently upgraded my wheelset to some nice Rhyno Lite XL w/ XT hubs. I had a choice of getting one that was recently built and one that they could build and have ready in a day or two. I chose the one that was already built so I could take it home and have fun with it.

Problem is the sales guy told me that the built one is a disc rim but could do well with centilevers or v-brakes. Is this true?


I still got the option to return.
I'm running cantilevers and want to upgrade to v-brakes.
Thx.

The Sun rims such as the Rhyno and Mammoth were designed to go both ways. Usually if it has faces you can do it, but do keep in mind rim brakes will eventually erode the face if used in mud or the like(not a real big concern on them though) Mainly cosmetic. The disc-only rims are typically round or shaped in some way as to not have contact faces. The Sun DS-2 that I now run are like that.

Good durable chioce to get the Rhynos. The will last ya.

I'd get clarification. Did he say it's a "disc rim" or "disc wheel"? A wheel = rim+spokes+hub.

If you have a disc wheel, then it must have a disc hub. It could have either a "rim brake" or "disc" rim. it doesn't matter.

A "disc rim" implies it cannot be used with rim brakes (ie cantilevers or V). "Disc rims" may not have the proper wear surface (shape, contour, material) or structural integrity required for a "rim brake" rim.

I guess the confusion lies with the term "disc rim". To put it another way, a "rim brake" rim can be used on any wheel. A "disc" rim can only be used with disc brakes wheels.

I have a set of Rhyno Lites and they're great, strong rims. Mine are for rim brakes. I am not sure if there is a a disc specific version of the Rhyno Lites. You might want to check Sun's web page, or call the peddler and just make sure you're on the same page.

Judging from Sun-Ringle's website, the construction of the Rhyno Lite XL rims are built for rim brakes.
In fact, as I understand it, Rhyno Lite XL and the Single Track are equivalent in sun's lineup/trim except for the Single Track is made specifically for Disc brakes.

Also, the XT hubs are disc and that's where the confusion laid, as you suggested.
I believe you have the same Rhyno Lite XL rims as I do and it seems that you have success in using v-brakes. I guess I'll go with V-brakes. I'm eyeing a set of Avid Arch Rivals and Avid Speed Dial 7 levers for $90 minus shipping. Is there a better deal out there?

Mechanical disc brakes look cool but I think they require a tremendous amt of maintenance, right?

No, mech discs don't require any more maintenance than any other brakes. Since I've had mine I've done exactly zero maintenance other than turning the pad adjusters a click or two every couple of weeks. I don't call that high maintenance. Also, cleaning the disc off to stop squealing is easier than cleaning the whole stupid rim. 10 minutes in the rain with discs and you'll never regret the upgrade.

Right, I'd say hydraulic brakes require more maint. Seems that I have to bleed mine everytime I get new pads (3 months). I've seriously thought about going back to mechanicals. I wore a friction hole in my rear brake line earlier this year while hauling @$$ DH. It was scary to say the least. Luckily there was a creek nearby to wash all the brake fluid off me & my bike's frame.... (Hayes uses DOT fluid which will eat off the paint in a hurry)

Wasn't too lucky for anything IN the creek.

DOT fluid is some NASTY stuff

I used to use mechs but the Formulas(bleck) were maint hogs. The Avids and Hayes units improved highly.

I disagree about hydros taking more maint. The maint is far less but it is more bothersome. I use a set of Shimano 525(Deore) hydros and love them. I'll never go back to cables. I miss the centering dial that mechanicals have, but they are simple as can be and they use mineral oil, which is really easy to get. So far I've only had to bleed them once (2 3mm bolts)out of a full season and that was because I got the pad-antisqueak gel a little too heavy(my bad). Pad changes are merely a cotter pin.

I'm pretty happy with my BB7's so far... They came on my bike... Obviously I wouldn't mind having some Juicy 7's, but they're a bit spendy for someone who does very little off road riding.
