I’ve written about my issues with them before on here, but in short over a 6 month period I had the first set of wheels which were plagued with the usual hub problems, a recurring freehub issue & a build quality issue surrounding spoke tensions & wheels going out of true.
These were replaced (after nearly a month with no wheels whilst Extra/Easton fannied around deciding what to do) with a new set, which promptly did the same, so they gave me my money back (after another month with no wheels).
I built a set of Flows on DT 240’s myself (first wheels i’ve built) after. 12 months later, including a month in the Alps, 2 Megavalanche’s & subbed numerous times for my DH bike I haven’t touched them once.
Even if I did, I could wander into any shop and buy off the shelf spokes & replace them myself, rather than farting around sending wheels off for spokes to be replaced if they break.
