TOSEEK Ultralight Alloy Stem — Adjustable Angle 31.8mm
⭐ Club Tested
Swapped one of these onto my hardtail to get the bars up a touch for longer rides and it made a noticeable difference to comfort without adding much weight. The angle adjustment gives you a bit of flexibility to fine-tune your position before committing to a shorter or longer length.
