Currently running XM819 on CK hubs (20mm front / fun bolt rear) on my 5 Spot, and would like to drop some weight – I like to run tubeless. What would you guys recommend?

Hope Hoops with Flows are the way I went and am very happy. The XM819 I used to swear by but they are narrower, heavier and not as ding resistant as the flows.

I’m not always a Hope fan but have always liked their hubs and the Hoops are a bargain.

Crossmax ST

Depends how heavy you are? you could get away with arch ex or even crests on hope hubs!

American classic wheelset fantastic tubeless lightweight,strong, and there are a few places where you may be able to buy for around £400 (retail at £500)

Hmm, I was going to recommend Traverse ELs, they’d be ideal for you, but can’t find anyone that sells them any more.

Stans Arch EX FTW. I’m totally impressed with my 14 month old builds. Nobby nic and hans dampf on mine. Light fast and grippy. What more do you want ?

Got Pro2’s with Flow EX rims. Lightest, stiffest and strongest wheelset I’ve ever owned… can’t fault them!

That’s pretty hefty- downhill-capable wheels. Light for what they are but not what the OP’s after I think.

Clee cycles has am classics at £419-00 a set

I liked my pro 2 evo on arch ex for AM duties

Rebuild the Hubs onto XM719’s lighter as you don’t need the silly double nipple things. Went tubeless with yellow tape only here. Also nice and tough.

Thanks for all your thoughts, was thinking I’d aim for something wider than 19mm too to give better shape to my Hans Dampfs.

mavic rims are too narrow. arch EX FTW

Got arch ex on stans 3.30 hubs
Thought they would be a bit to light but have been very impressed

😆 sweeping generalisation…

Current stuff comes up about the same on my EX721’s, XM719’s and compare fine to other wheels round, the 25 & 29mm rims are obviously wider….

What weight are the current wheels roughly?

Have you considered Light Bicycle Carbon Rims?

I’m very impressed with the pair I’ve built up onto some Hope Evo hubs. Less than 1500g for the pair (laced with DT Revolutions and alloy nipples).

Keep your CK hubs?

sweeping generalisation…

not sweeping, as it’s true

I’ve had 29mm mavics 🙂 they were nice and wide.. They are measured in the same place according to the tech docs too

Flows on Pro2’s are not going to be any lighter than his current set up. Both my pairs came in at around 1880g with valves and yellow tape while my 819/Pro2’s were 2005g including valves, and I think King hubs are slightly heavier than the Hopes aren’t they?

The 2012 Easton Havens on CRC are probably worth a gamble at £360, they are full UST. Earlier hubs had sealing issues and problems with the pre-load adjuster backing off but I understand this has been addressed on the 2012 version (and if not there’s a free upgrade available). I like my 29er version a lot. If your budget is slightly higher it might be worth looking at the new Syntace wheels. For 600 Euros you get a nice wide 30mm rim and wheel weights of around 1500-1600g. I’m quite tempted to try one of their 29er offerings.

2nd the Light Bicycles carbons.Build them onto your Cks with some D-lights and bontrager rim strips.OOsh.

Syntace wheels are lovely but if you want front and rear then its about 950 euros, Spank do so e quite interesting rims if you want something different from the usual Stans offerings.

To the chaps recommending carbon rims and building a wheel yourself. How tricky is it to build a with the carbon rims? Suitable for a first timer wheel build or practice on something old first?

I picked up a new pair of American classic all mountains for £350 at 1600g.

Saving for spank evo oozys at £370 and 1650g

It’s no more or less difficult than building with alloy rims. And I third the light-bicycle carbon rims. I have them built on DT 240s hubs and I’m rather pleased with their performance.

I’ve had 29mm mavics they were nice and wide..

says all mountain, not DH

+1 for Crossmax STs. I’m running a set on my own 5 Spot for exactly the described useage, running Hans Dampfs and they are spot on. Light, stiff, strong. Only downside is that Mavic rims aren’t very wide but they support the HDs just fine and mavic rims and way more ding proof than most of the competition so you win out on durability there. Proper UST compatible too.

I can’t see why you would want to (or why people are recommending that you) replace the Chris King hubs.

Get them rebuilt onto Stan’s ZTR Arch EX rims which are tubeless compatible, wider and lighter than the Mavic XM819.

another vote for Crossmax ST. I replaced a set of hope hoops (pro2evo on crest) with ST’s.

I find the ST’s better in everyway. They are faster, stronger, engage quicker and tubeless just works.

Only downside as robinlaidlaw mentioned above is the rim width, but they are fine for my trail bike with 2.35 minions.

I would replace the rims with Arch EX.

I picked up a new pair of American classic all mountains for £350 at 1600g.

where abouts did you get these from?

What messiah and Rorschach said, get your hubs rebuilt with light bicycle carbon rims
