What Our Gearhead(R) Experts Are Saying:"The G SES 4. 5 is the wheel I'd spec for courses where fast gravel descents, loose climbs, technical singletrack are all mixed in. It's light enough that I don't notice it going up and noticeably aero on the fast sections."Why We Like ItThe G SES 4. 5 uses front and rear rim profiles shaped independently to smooth airflow at the 44-52mm tire widths gravel riders actually run. Wide Hookless Bead construction, carried into the G SES line from ENVE's mountain wheel program, dissipates impact energy at the bead to reduce pinch flats on rough terrain. The rims are hand-manufactured at ENVE's facility in Ogden, Utah.
