This new generation of hubs flanges for Straight Pull spokes set new benchmarks in every aspect. Weight is really extraordinary: from only 89 grams and 183 grams for the front to the rear. The internal mechanism presents axles with variable geometry, a new Bearing Preload System with a stainless steel grub screw locking. The broached titanium ring has now 56 tooth (was 28) on which simultaneously act 4 pawls with triple-engagement tooth profile. The doubling of the point of engagement halves the pedal lag time and allows a faster acceleration response. There are versions for quick release or thru axle and compatible with the RockShox RS-1 fork. The freewheel can be optioned for Shimano, SRAM XD or Campagnolo drivetrains. Available are also models with enlarged spacing like Boost 110 and 148 and for Lefty 2.0.
