Our review

Super bling and light but hyper expensive and still flexy.

It’s light and it’s flashy as hell, but with this stem you pay for the honour.


According to Ritchey their carbon wrap over alloy body is a “new frontier of material and manufacturing technology”. The same clamp design as the Syncros stem makes it flexy though especially in such a thinwall structure. A slanted rear slot with opposing bolts makes it suitable for the most delicate fork steerers while flip flop decals mean you can invert if for racer low bar position.


We’re slightly concerned about using carbon bars with the internally knurled face plate though. Ti bolts are designed to be used with Ritchey’s ‘Torqkey’ for those without a torque wrench.
