CNC-machined from solid aluminium, the Terra Emblema is a 40mm reach super lightweight stem for 35mm clamp bars. With steel bolts, it weighs a claimed 110g. Swap those out for titanium ones and you knock the weight down to 99.3g.

Terra Bikes say the design focused on placing material at the points of maximum stress, and removing it from areas that experience less stress, allowing them to keep the weight as low as possible. Certified according to ISO 4210-5, the Emblema stem passed all the static lateral and frontal flexion tests it was subjected to.

  1. None Given on

    About a year ago I almost got a stem (ultra light) from another company. I hesitated based on the clamp style. Low and behold the internet has many stories about them becoming loose at bad times. Just the other day a friend of mine had the exact same stem come loose at a very bad time….to me, stems are just maybe not the best place to save weight (coming loose is part of the thin AL “straps” stretching over the 35mm radius and eventually closing flat on the stem face – becoming permanently loose)
