ASTM5 (build for severe abuse by heavy people) UST Mountain bike wheels. 30mm internal. Last wheels you will have to buy. Mavic doesn't make a stronger wheel, and still kept them at 1900g. 200g heavier than carbon with 5x the durability. Boost specs. Sram XD driver or shimano.
Impossible to find here, I ended up ordering them from France and not using these. Comes with large bladed extra ZICRAL spokes, etc. $1299 retail,
NEW, $875 for 29", $799 for 27.5.
USED 27.5" or 29" set, $595, perfect condition with XD or Microspline freehub driver.
If what you want is the toughest, most reliable wheel that you never have to tape, you have found them. No carbon wheel can hold a candle to these. And you will never need a warranty with these either, unlike carbon.
