2011 Trek 'Gary Fisher' SuperFly 100 Elite 29er Mountain Bike

Related: mountain biking

For the 2011 Trek to the Summit of White Mountain Peak, Trek Bicycles sent us two of their top of the line mountain bikes, the Trek Top Fuel 9.9 SSL and the 29er Trek SuperFly 100 Elite. See the Trek Bikes web page.

Weighed with Shimano XTR pedals at 25.1 pounds, ready to ride.

Trek SuperFly 100 Elite 29er 2011 model
With SRAM X.0 2X10 drivetrain, Bontrager Scandium Race X Lite 29 wheels,
Fox RP23 with Race Tune Boost Valve, Bontrager carbon handlebar and seatpost.
Delivered without pedals, Shimano XTR Race pedals shown


See also the image gallery.


The SuperFly 100 Elite was standard setup as follows:

  • SRAM X.0 2X10 drivetrain with 39 X 26 front chainring gearing;
  • 11-36 rear cassette;
  • Bontrager Scandium Race X Lite 29 wheels;
  • Tubeless ready wheels and tires, but delivered with tubes;
  • Fox RP23 with Race Tune Boost Valve;
  • Bontrager carbon handlebar and seatpost;
  • Delivered without pedals, Shimano XTR Race pedals added.


After removing 102g of nanny-state reflectors and adding Shimano XTR Race pedals, and switching to a tubeless setup with Stan’s sealant, I weighed the SuperFly 100 Elite in at 25.1 pounds. Be careful removing the reflectors, as the carbon fiber scratches easily, as I discovered.

A pair of 29er inner tubes weight nearly a pound, and switching to the tubeless setup did indeed drop a full pound off the bike weight, from 26.1 pounds with tubes to 25.1 pounds tubeless.

Any realistic setup will need to add a spare tube (even with a tubeless setup), a pump and/or CO2 cartridge, patch kit, etc. That is likely to add a pound to the riding weight. Races might be able to dispense with that, but everyday use must be more practical.


See the 2011 Trek to the Summit of White Mountain Peak.

Gearing is a front 39 X 26 dual-ring setup with an 11-36 rear cassette. On very steep climbs (15% or steeper), even the 26 front X 36 rear was a bit low rpm, and I’m a strong rider. The large 29er wheels effectively cut that ratio down by a full gear over a 26er, since the 29er wheels are 1.1X different in rolling distance per wheel revolution.
