Sea Otter 2011: Marzocchi ultralight Corsa 29 cross-country fork

Sneak preview of 80/100mm travel fork due out in September

Marzocchi offered up a sneak preview at the Sea Otter Classic of their new Corsa 29, an ultralight, 80/100mm-travel cross-country fork aimed at the 29er crowd that is set to be released this coming September. 

Target weight is just 1,590g (3.5lb) – the same as RockShox's new SID 29 – largely thanks to a new one-piece carbon fiber steerer and crown.  The 32mm-diameter aluminum legs are nickel-plated to reduce friction and the cast magnesium lower legs will be offered with 15mm thru-axle dropouts exclusively.  Marzocchi plan to fill the structure with an air spring on one side and its TST Micro damper on the other with adjustable rebound, compression, and blowoff threshold.  An optional remote lockout lever is also likely to appear this fall.

Projected retail price for the Corsa 29 is a premium US$1,000 but Marzocchi also plan on releasing a second version with steel upper legs for a much more attainable US$599.  This version will of course be heavier – though probably not by a huge amount – but the steel stanchions should also boost stiffness, too.

James started as a roadie in 1990 with his high school team but switched to dirt in 1994 and has enjoyed both ever since. Anything that comes through his hands is bound to be taken apart, and those hands still sometimes smell like fork oil even though he retired from shop life in 2007. He prefers manual over automatic, fizzy over still, and the right way over the easy way.
  • Discipline: Mountain, road, cyclocross
  • Preferred Terrain: Up in the Colorado high-country where the singletrack is still single, the dirt is still brown, and the aspens are in full bloom. Also, those perfect stretches of pavement where the road snakes across the mountainside like an artist's paintbrush.
  • Beer of Choice: Mexican Coke
  • Location: Boulder, Colorado, USA
