I'm sure it's not your rims that's the problem but the way they were built.

Nope, i'm a wheel builder myself...its the rims,they cant handle my weight combined with the rough terrain. 

[TheLegend]

a wheelbuilder should know what rims to use!?

I would suggest Mavic XM819 (Disc or V-brake option)

They are strong and you won't have to do a tubeless conversion on them...

i GOT some sweet rims your you, was keeping them for myself for the day I get some Disc's but that day has not come yet: They are lekka light at 350g per rim: http://www.sun-ringle.com/contentpages/mtb/rims/xc.php5 the Equilizers - R800 for both.

Are these rims made of paper? Perhaps you can be more specific and tell us what your weight and rough terrain does to the rims as they roll.  I don't understand how the rims cause the wheels to go out of true.

 

What brand of rims are these and what properties must the new rims have to prevent all these maladies?

What makes them so strong?

[GoLefty!!]

their weight...

[Johan Bornman]

their weight...

 

 

He he.....I'd love to see the converse of that.....in marketing speak

[GoLefty!!]

Ah the one where they talk about acheiving unsurpassed strength while making the rim disappear?

 

the ad did not make it past the ASA...

Hehe, well, ....mr spanner, i'm the wrong side of 85kg's and going at 60km/ hour at my last mtb race...trough pot holes..those wtb speediscs... they were not happy, not happy at all, the website state their weight...450 grams....light and weak...... I need the mavic's a bit heavier but alot stronger... double wall alloy ect...vs...single wall.... I must say the mavic website...is a must to look at...they point you towards the rigth rims for rough riding im going with ...a heavy set of mavic's

I don't know what a hub looks or reacts like that is "not happy." Surely you should be able to describe the syptoms a bit better?

 

You reported that the spokes need contant re-tensioning and then attributed the cause to lightweight rims ridden at very high speed over and through potholes. Something is amiss here. Lightweight rims (or any other rim for that matter) show other symptoms of failure than what you are describing.

 

A wheel ridden at 60kph into potholes fail by simple bending. You would have experienced a snakebite flat, a rim bead bent or entire rim deformed and spokes that are now several centimeters too long for the flat part of the rim. A simple retrue would not have fixed them.

 

I don't understand how a rim can be "a bit heavier" but "a lot stronger." Strength and weight is linear for similar shapes. It is either a bit heavier and a bit stronger or a lot heavier and a lot stronger.

 

But still, strength is just half the story. Durability is also pretty useful. I bet those Mavics you covet for their strength only have a single eyelet....oh dear.
