Need new rims - can use vbrakes with disc wheelset?

[zerpy]

I just messed up my rear wheel, screwed up the spokes with the chain. I think it will be OK for riding with for a while, but the wheel has a definate wobble to it and the spokes where my chain dug in are kinked. Since the stock wheels that came with the bike are real cheapies, I suppose it isn't worth while to have them rebuilt, maybe I'm wrong. But...

At some point I would like to upgrade to disc brakes. I'm thinking next spring. So, if I buy a set of wheels I'd like to be able to use my vbrakes on them now and then put the disc's on them. I've seen some wheels with shimano, lx or xt disc hubs and sun rhyno lite rims at a pretty decent price (~$100) and they probably kick butt over the stock stuff that came with my bike. Does anyone know if I would be able to use the rim brakes on those rims?

I know that I should really have mavic whatever rims and chris king hubs, of course! :crazy2: I don't know if these are going to stand up to intermediate loop very well but I can't justify 500 bucks + for wheels...

:)

thanks

Yes, the rynolites can be used with either disc or rim brakes. Of course the wheels will have to be rebuilt when you switch from rim to disc.

Might wanna also check out the 2004 Mavic Crossland wheelsets coming out soon.......they are a kick butt nice priced $250 or so set of wheels that are a disc hub built on a rim brake rim. So they can be used for either tyoe of braking systems....they are also able to be used for both tubed and tubeless tire systems. I got me a set coming for my "everyday" wheelset....lemme know if ya wanna check em out. Id strongly consider them.

If I got them with disc hubs, then why would I need to rebuild them?

Hey Douglas...

Well, if you normally keep them on your bike, then mabye next time we get a chance to ride together I can check them out!

That is a lot more than I was planning on spending for wheels - I probably don't need anything like that. But, it all depends on when I'm going to need to do something.

Thanks

What the?!?!?!

It says "Bike Guru" next to my name... someone's going to get me for false advertising...:)

Just because I ask a large volume of stupid questions doesn't make me a bike guru!!

Right, I misspoke.

$250 for a quality set of wheels is not that much by wheel standards... You could spend a whole lot more.

Of course I could spend a lot more, but I could have bought a $4000 bike too (if I had the moolah anyway:crazy2: )

So I guess that begs the question, what kind of benefit would I gleem from spending 250 on wheels vs 150? Is there going to be a lot less rotation mass that I'm really going to feel a benefit? How about durability? I'm worried about durability going down as the weight goes down as well. With my current cheapie stock wheels I did about a 3 foot drop onto concrete (very hard landing too as I didn't know it was coming nor how to 'do it' properly) and my wheels were fine. I remember trashing wheels on my BMX when I was a kid doing stuff like that.

So, anyway - this is good discussion. Getting me thinkin'! :) But what will I gain and especially at my riding level (out of shape newbie) what is really worth while?

[zerpy]

So here's another question? Has anyone ever damamged a wheel by "stopping too hard" with disc brakes?

With rim brakes, the spokes aren't being loaded with the same forces as disc brakes. With disc, you are essentially stopping the hub, where the inertia from your mass is applied to the rims via friction. All that strain has to be beared by the spokes and the rims where the spokes attach.

With rim brakes you still have your effective mass pushing against the hubs which push against the spokes, but the mechanism there isn't much different than gravity when you are sitting there, just a different direction.

I'm not a mechanical engineer so I won't even attempt the analysis, it just seems there is more strain there with disc brakes. Which might not be a bad reason to go with better stuff if there has ever been a proven case where that is necessary...

A lot of the benifit to a more expensive wheelset is weight. You also get better hub bearings, stronger rim, and better/stronger spokes. You'll also get a better built wheelset as well.

I would say for a normal hub/spoke/rim combo wheelset, you may wanna go with say a 36 hole Deore disc hub with Rhyno Lites and build with DT Swiss 14/15g in a 3x pattern. That way you get a strong as an OX wheelset that can be used for both braking systems when you decide to change.

Well, that's not all that far off from what I've been looking at. Yes, I do want light, but at some point you get this diminishing returns that may not be worth while for a rider like me.

I guess we'll just see what I can afford when I am ready to get them...

thanks for the help!

36 hole might be overkill though, I ride 32 Rynolite on my hard tail and I haven't had any problem. I guess I can't really speak to any issues of using the wheel for both rim and disc brakes, that's why my initial comment was that you would have to rebuild the wheel.

And yes I have popped spokes braking on a crappy wheel with disc brakes. I also did it climbing steep hills in the granny gear, too much torque. Just part of the joy of being a Clydesdale I guess (good gear helps though).
