Aero MTB or Comfort Gravel.
Simple, bolt-on design that can be fitted to all 31.8mm handlebars within minutes. (NOTE: only needs 2.5~3Nm to tighten on the handlebars)
Allows for additional hand positions on long rides as well as creating an aero-tuck position should you wish to power along on the flats.
Sizing is similar to most popular GPS/Powermeter attachments and does not protrude excessively in any way.
Matte Carbon Finish.
