Had a good look at this rather nice titanium stem at the Taipei Cycle Show. It’s part of Control Tech’s TiMania range which includes flat bars and seat post (31.6 and 27.2mm). Notice any welds? Thought not. This is the first monocoque Ti stem (that I know of). It’s 138gm for a 120mm version which is light enough and has offset steerer bolts to help stop over-tightening. Nicest production stem I’ve seen in some time. Would look nice on my bike too.
