Somewhat DH worthy XC rims?

DHS · Jul 21, 2005

Sun MTX rims, Arrow FRX rims. i wouldn't go any lighter really. the new 823s are suppose to be really good.

"Any other suggestions?? Having lighter rims will force me to not be stupid and not try to run over things I should be riding around." - sounds like you wanna ride XC.

Good 'ole Mavic 521 (or whatever they are labeled now, 721?). They have always been good to me.

Mavic XM321's...........

wydopen · Jul 21, 2005

i have 3year old rynolytes on my slalom bike and that thing gets beaten and they still roll...they may have some flat spots but after that long it dosnt really matter

Check out the Sun SOS rims. Same profile as the SingleTrack rims, but 3mm narrower and lighter. They were originally only OEM on the 05 Spec. Enduro and now you can buy them aftermarket.

and soon you can get the SOS's in urban camo finish...nifty

XM321's (confusing w/D321, X3.1.. etc)
Mavic 519, 219 can both be had pretty cheap and hold up pretty well.

Check out universalcycles.com they have good deals sometimes.

I think XM321's are the old 219, 519.........i'm not sure though......if that's what your saying....

Biscuit · Jul 21, 2005

I get really confused with the whole non-sensical number switching.

I think the xm321's are a tubless version of the 219... I think.

The 519 is a "non-disk" rim, but it's light, welded (not pinned) and cheap if you can find 'em.

Cane Creek Duros?

I thought the FRX rims were still really heavy...or just as heavy as my Atomlab DHR rims.

Your thinking of the DHX rim which is coincidently still lighter than a Atomlab rim...

konahucker43 · Jul 21, 2005

the xm321's are the new 219. good rims and very light. they are not tubeless thou

Five · Jul 21, 2005

I've been pretty happy w/ my singletracks.

vitox · Jul 21, 2005

dt has a rim called the 6,1 that is lighter than most dh rims and totally dh-able, its pretty much a narrower 321

old 521 or whatever its called is also a good choice, syncros has a good looking rim line, for what youre after i think theres one called the ds28

i'm running xm321's on my big bike currently. after a couple months (whistler & northshore) the rear is getting polygonal, and the seam is opening up (its pinned, not welded) - the rim is pretty much done. the front is holding up fine, though. they are about as light as i'd risk for dh use (570g), and seem to do the trick if you're not heavy, or a basher. i'm going to use rhyno xl's on my next wheelset, however - they're about the same weight, with a welded seam.

i have a 219 on the front of my bike. i think its garbage.

JRogers · Jul 21, 2005

Rhyno XL works well, especially for the price.

For a light DH rim, however, I don't think anything beats the 521/721. Built right, that rim can be incredibly strong.

ioscope · Jul 22, 2005

Rhyno's are so skinny though, I say singletracks. Just use DB spokes. They really are just as strong, spokes never break in the middle. Flexier though.

for real?

decent suggestions above for standard rims that'll allow you to save a little weight.

however, think hard about your intended use and the overall weight of the tires / tube / rim (or sealant).

if you look at the 823 rims (new version, which appears to be stronger) plus the nipple adapters, you're looking at around 610 g, which at first glance isn't impressive compared to non-UST rims that are way wider.

but if you're only planning to run 2.4 or 2.5 tires (real width, not skinny maxxis widths :rolleyes:

) they you gotta decide between lighter tire casings plus heavy, pinch-resistant tubes, or heavier DH casings that some (not all) riders can use with light XC tubes.

Then compare that to a true UST tire like the 2.4 Specialized Enduro D2 Pro tubeless at 930 g, and consider the overall advantages: mounts really easily, any pump will work, overall lesss hassle than using Stan's and a non-UST tire, relatively burly (for a single-ply) sidewall, and since the bead is already self-sealing, you don't need much sealant in the tire sloshing around---just enough to handle punctures. I'm using the rubber-containing Sliime for tubeless you buy at motocross shops, cheap.

I wish the mavic 823 were wider and lighter :cool:

but just as strong...then it'd be a no-brainer. Still, as it is, it's a pretty good solution for a lot of riders. You just have to think about how wide you want your tire size to be, and whether you need the advantages of a truly wide rim.

OGRipper · Jul 22, 2005

321s have been holding up pretty good for me. I've heard the pinned joint can separate, so far no problem but one of the welded -21 series might be a better call.

I have these tires and I love them.

xy9ine · Jul 22, 2005

speaking of rhyno xl's... can anyone confirm the erd? i've seen it listed on a variety of sites as 544 and 548. which is correct?

xy9ine · Jul 23, 2005

the sun website actually conflicts itself - thus the confusion.

DROP · Jul 23, 2005

defenetly go ryhno lite they seem to hold up well and ive been using them for d on a hardtail.

h22ekhatch · Jul 24, 2005

I have a pair of F219's that I have been absolutely abusing for the last few years...they have held up well. They are a bit narrow tho, makes it hard to put on some of the bigger tires.

FWIW I weigh about 235 so I am not a lightweight rider

JTVW · Jul 25, 2005

what about WTB's rims? DH or dual duty FR?

dhtahoe · Jul 26, 2005

WTB Dual Duty. Just a copy of the old Mavic D-521. I have punished the same set at N* for three years.

dropmachine · Jul 26, 2005

Wouldn't it be cheaper, easier, and faster to just realize that bike is a pig, and always will be no matter what you hang off it?
