BOX HOLLOW STEM
Hollow stems are CNC-machined from the highest quality 6061-T6 aluminum. They feature a
skeletal design that keeps the weight extremely low, while maintaining a high level of strength.
The most unique feature of the stems is the mid-bolt wedge mounting system. By removing the
rear pinch bolts and moving the mounting bolts to the middle of the stem, we reduced the weight
and overall bulk, as well as eliminated a significant hazard to the rider’s knees.

Crupi I-Beam stems are CNC
machined and a spin off of
our very popular groove stem
from the mid 90’s but with
many revisions making it a
very workable stem! And it is
lighter than ever!!
HOLLOW MINI STEMS
Mini Hollow stems are cold forged from the highest quali-
ty 6061-T6 aluminum. They also feature an open skeletal
design and single mid-bolt wedge mounting system,
making them among the lightest weight mini stems on
the market. A 40-millimeter extension stem weighs just
132 grams grams/4.6 ounces. The Mini Hollow stems
have a single-bolt wedge clamp, meaning there is no
rear-facing pinch bolts to injure the rider’s knees.
