Stans No Tubes ZTR 29-Inch 32 Hole Presta Valve Crest Rim (Black)
ZTR Crest is the best of both worlds. All the wall thickness and corresponding durability of a 355 with the next generation BST creating a wider rim cavity with shorter sidewalls. Fully tubless with addition of NoTube's 21mm or 25mm rim tape and valve stem.
