Hi guys,

I know that there is a specific forum, but I think that some of you might give me a good advice.

Most of the time, I ride downhill. But during the winter break I ride a lot on my trail Bike (Iron Horse MKIII).

I run Mavic 721 on Hope Pro II Hubs, which I ride on my dh rig too, but the seam a little bit to mutch on a Trailbike.

So i'm thinking to switch to Mavic 719 or DT Swiss 4.2.

Which one would be better for a downhiller on his trail Bike?

719s would be your best idea. very nice a durable rim. but still a good weight

Which 719 are you talking about ? Disc or Rim ? The profile on the rim version looks like a mini 721/521

Avoid the DTs...run a few searches and you'll see why. Apparently they're made from frozen butter. Just word of mouth, though.
I STRONGLY suggest any wheelset with a SunRingle MTX rim, and there are several setups. I'm now on the A.D.D. setup and LOVING IT! I also have an MTX based wheelset on my street rig and it's STILL surviving my hacked out 360 bunnyhop attempts. That's pretty good...

the mtx is a very hefty rim though. what do you weigh? there is no reason for you to be buying a DH duty rim on a trail bike unless you are really hard on your wheels or are very heavy. check out the syncros ds25. i'm actually running the ds23s on my light wheelset for trail riding, and even though the wheels have seen light downhilling and a bunch of drops, they have survived shockingly well. the ds25 is a beefier version made for aggressive trail riding, and with a good wheel build, they'll last a long time.

if your on a budget, i'd recommend the azonic outlaws. i've run them on both my DH bike (R9) and my trail bike (heckler) and they have mostly held up to the abuse i've thrown at them for 2 years now. they aren't too heavy either.

at the price you can get them for, they are pretty much a throw away set of wheels if you thrash them anyway...

Outlaws are heavier than MTXs!
But yeah, they MAY be overkill for a trail bike... unless you're an idiot like me and just can't avoid airing it somewhere over SOMETHING just cuz it's there...

Are you looking for a complete wheelset or just rims? Check out the rims from Syncros. I'm running the DS28's on my trail bike and ran them on my hardtail without fault. They also offer some fully built wheels.

Keep the 721s on the Hope's for the trail bike dude. The hope hubs are as light as they get and and the 721 are way more durable&not too much heavier than lets say 819 or 719 rims. Not worth the small weight savings in my opinion. Just put lighter trail tires on the wheelset you have now, that will save ya some real weight and get a badder dh wheelset like Hadley-823s and put your big tires on those!

But really I think the hope pro2 hubs + 721s is the best and lightest all around (dh-freeride-trail-dj) wheelset you can build!

I'm quite pleased with my DT Swiss Onyx/DT 5.1 combo on my "heavy duty" trailbike. Rims are holding up fine after plenty of abuse.

Thanx for your comments!

I only want to change the rims, the Hope Hubs will stay. The main reason is that i want to build a secound DH whellset for my Dh rig, so I would use the 721s there.

So maybe I will try the 719 Disc......................

721 and Hope is going to be tough to beat. Good middle of the road solution. What is Hadley weight penalty over Hope II ? Can't be much.

I just built up some Mavic EN-521's on Hope Pro II's for a buddy. Nice rim! 540g, 28mm wide. They are holding up pretty nicely so far with a 200lb agressive rider at the helm.

sun singletrack (590g, 31mm)
or
sun rhynolight XL (565g, 29mm)

you can score either of these rims for $20 from universalcycles.com

buy 3/$60 and have a spare laying around, ready to rim swap if something catastrophic happens.

Have you considered the DT EX 5.1 rim? If your choices were the Mavic 721 and DT 4.2, this rim is right in the middle. Some 500g and 28mm wide... good stuff.

For winter riding, I prefer these since the wideness of the rim increases the tire width a bit. Most studded winter tires come in ridiculous 2.1 XC sizes. Does Austria get snow in the winter anymore? :shocked:

find some second hand crossmax xls you should be able to pick them up cheap enough there bomb proof and weigh feck all. I've seen Ben Ried running the front one on his dh bike at some of the irish races and i know he uses them on his 7point. I use them on my enduro and find them great.

yeah i was going to suggest the havoc AM wheelset, which you can usually find new for around 400 bucks on ebay.

but he says he wants to use his hope hubs, in which case i'd recommend dt 5.1 rims and 14/15 spokes.

my hope pro II hub / 32 H dt 5.1 / 14/15 spokes / brass nips weighs exactly 883 g; the easton havoc AM front wheel weighs...883 g.

the inner rim width on the havocs is 22.5 mm, just 0.5 mm wider than the dt 5.1.

i wouldn't say my havoc ams are stiffer than my 32H wheels, but they are pretty stiff and have held up well to my 195 lbs. good AM wheelset for sure.

Hi,

we get towns of snow every year, except last year was complete s***.

I did not hear to many good things about the 5.1 Rim....

Schade.... Southern Finland (Helsinki area) had about 1 week of proper winter, too.

The EX5.1/Hope bulb set I built two seasons ago are still holding up fine. I was able to get the build down to 1.9kg using alloy nipples and triple butted spokes. So far they haven't needed any major truing.

So how does this option allow him to keep his hope pro II hubs on his trailbike? :plthumbsdown:

it doesn't but if he wants something seriously lighter and just as strong i reckon its his best bet. I just switched out my dt440/5.1 wheels for crossmax xls and have gone tubeless. It made a fairly noticeable difference to my bike. I run Pro IIs and 721s on my dh bike and unless he's wrecked every set of wheels he's had in the past its probably over kill for a trail bike. All i was doing was making a suggestion of an alternative that wouldn't cost a fortune. As you can pick up crossmax xls used for about the same price as a pair of rims, spokes and wheel building.

I got a pair of minty Crossmax XLs not too long ago for 300$ shipped. Great wheels, light and surprisingly (to me!) pretty damn strong. I run them tubeless and I save tons of weight on my hardtail in comparison to when I have my king-x721 wheelset. On the other hand, I don't feel as confident on them as I do with my King wheelset. I think Ive gotten used to the 72 engagement point standart......

I say get some single tracks.. sorry if anyone disagrees but i'm just a huge fan of sun's rims for some reason. I definitely dont think i would put mtx's on a trail bike though. they weigh a little more, i want to say about 60g more a wheel.., but they would be a little overkill for a trail bike

I agree on the lighter rather than stronger thing. I think most trail rims or even xc rims would work well. XM719s would be just fine. A trail bike, unless you're really sending it, puts a lot less stress on parts. I race dh at a middle level (expert), go pretty fast on trail rides, ride pretty rocky terrain and run xm819s on my trailbike. I haven't had any problems in the few years I've been using those rims. I've done a few stupid things with them (raced slalom, did some lift-served dh, cased some big jumps) but they've held up fine.

I'd rather have a nice set of new rims on hubs I like w/ 32 spokes that don't weigh much more than the xmax xl's, but that's me...

Depending on the riding the OP is doing, Singletracks or other ~600g rims are probably overkill. I've had good luck so far with my Sun SoS rims which look like narrower versions of the Singletrack and are closer to 500 g. If you prefer Mavic, then get the rims that compare to the xl's for a similar weight as the xmax's. And save the money on getting the wheels built and do it yourself. It's not that difficult...

The combination works so well, that Hope even sells it as a factory wheelset. I've only seen this sold in Europe, though. Strange.

You can buy them online via www.chainreactioncycles.com for very little cash. I bought a set, cost NZD650 including postage, arrived in 9 days. The only issue was they sent the wrong axle adapters but that was a packaging problem at Hope. I contacted Hope and they send out the correct ones straight away. :thumb:

I've had a couple of rides on them, but they are fast and light. Coming off a set of XMax XL's I am very impressed so far.
