“DT EX500
Mavic 521
ZTR Flow”
Stans Arch EX are as wide as the Mavics, but about 140-150g lighter for a pair of rims?
What forks do you have on the meta?
What tyres (and size) do you typically run?
If you’ve a really ‘burly’ setup then the wider (but heavier) flows might complement it better?
“Mavic 717s”
Eh? No. Really narrow, fairly easy* to ding the rims, 4mm wider Stans Arch EX are the same weight as XC717 discs
*though it depends how much you try riding up steps and stuff
I have one on the back of my XC HT though, and is fine on there though
“What about the mavic 321 has the strength but also light “
OP already suggested the lighter (less heavy) 521
321 isn’t light, claimed is 570g no? And IIRC that isn’t a real world weight either, excludes something, might be the rim eyelets, so will be over 600g? Same width Stans Arch EX will be over 200g lighter
“I think the new EX version is a further 25g ligher or something”
Yep, and 2mm wider internally, plus IIRC the different ‘bead technology’ means the tyre will sit wider for the same rim width
“i have the Ex5.1D .. they are a real PITA get tyres mounted”
My brother tells me this about his. They’re harder than mavics yes, but I wouldn’t say they were that bad on the whole. Maybe if you tried a few year old (but never used) bontrager TLR or something, but then they’re a real PITA even on mavics
“i want strength at back and lightness at front basically”
Yeh but .. Id want stiffness/tracking and width at the front (crests are supposed to be much flexier than arch/archEX/flow’s) and the rear I’d be less concerned about
I’ve think I’ve decided on ArchEX, just need to justify spending the money when my (too narrow) XM719s aren’t at all broken
