Have: Nitto Technomic forged quill stem, 90mm length, for 1" threaded fork and 25.4mm bar (though I've used other 25.4mm stems with bars that were ostensibly 26.0mm - YMMV). Stem is used in good condition, with staining below the min insertion mark.
Need: 90mm stem for oversized 31.8mm bars and 1" threadless steerer.
