Gravel Geometry Lug Set, Sloping or Horizontal Top Tube Option

Description

This gravel geometry lug set was specified by Chris Bishop of Bishop Bikes with the intention of creating lugged gravel frames.

The DT-HT angle is steeper to allow for both a taller fork and also lower bottom bracket height. The set uses a 34.9 down tube for a more stable ride and also 31.7/28.6 tapered top and seat tubes. Top tube lugs are available with either the option for a horizontal or 5° sloping top tube. With some manipulation the 30 x 16 oval chain stay sockets will accommodate road straight or 'S' bend stays.
