Review: 2013 Trek Superfly 100

29er All Mountain Trail

What is it?

This a full suspension race bike from Trek and it is about a pound lighter than last year’s frame. Other changes are a 10mm reduction in travel to 100mm and the suspension was tuned for a firmer feel with a more progressive stroke. Trek engineers raised the bottom bracket 5 mm for more clearance and slackened the head angle by 1 degree to meet the demands for slacker head angles these days. Despite losing a pound, the frame is stiffer than the previous model, Trek claims. Prices for this test Superfly 100 Elite SL model is $5,570. A $9,030 Pro SL weighing in at 21.4-pound is available as well and it gives a glimpse to the Elite SL’s upgradeability.

We rode the Superfly 100 for about a three months on our local hill climbs, twisty trails and big descents. Below are our observations.


  • A full pound lighter than last year’s frame
  • It’s a full-on race bike with slightly less travel and a little higher bb than the previous generation
  • The spec is excellent from the components to the bars and saddle
  • It’s purpose-built for speed with no compromises
  • Dropper post compatible with internal top tube routing
  • Stiffness is excellent and better than previous generation
  • Delivers a good value for the level of frame and components in the XT package
  • The wheels are plenty stiff with one of the best tubeless systems available
  • The frame is a work of art and it is finished well with internal cable routing and down tube protection system
  • 23.85 lb actual weight for medium without pedals is very impressive

Impressive carbon fiber work for drop-in bearing for headset.

Chainstay protector is fully designed in with a little rubber tab on the bottom to minimize chainslap noise

    • Dan says:

      Which brand are you riding. I’m in the market for a new bike and feel $5900 (with tax) is expensive too. Any recommendations?

  • Dan says:

    2013 is made in Taiwan. 2012 1 pound heavier is made in USA. Trek continues to lay off workers without giving them a chance while raising the price of their bikes. Now that is a good deal!

    • jeff says:

      Don’t forget that it has less travel and a higher BB so basically there is nothing revolutionary about it… just less frame.

  • mtnbike1 says:

    Does the Superfly still have issues with cracked carbon frames? This was a real problem right during the Fisher buyout, when the only 29er carbon frames available were the Superfly and Santa Cruz Tallboy. Fortunately I went with the Tallboy at the time, but did love the speed of the Superfly.

    Just like other expensive sports: There will be two seasons for MTB racers, racing season and sponsorship finding season… 😀

  • roger says:

    There’s nothing wrong with your current bike setup. It’s the rider that’s need to loose the weight! Why is this bike made in Taiwan at pennies on the dollar cost more than my car again?

  • pmiddlebrook says:

    For that cash I can buy two bikes and produce different values and exceed the one goal of trek. Lost and confused and sales will validate that effort. A good re-buy on ebay. Trek maybe light but uncomfortable in xc racing and long trail riding which makes up 50% percent of the market.

  • Zachariah says:

    Look at the tiny head tube gusseting and thinner down tube. They turned what was one of Trek’s stiffest, carbon platforms into an understated, ugly noodle now. I’ll keep my flashy, uber-stiff, 110mm rear travel 2012 SF100 Pro that weighs a pound heavier any day.

    Note to Trek: Brace yourself for future warranty claims….

  • Jan Minnie says:

    I purchased my 1st superfly 100 in 2010. Warranty claim for another in 2011 and now again warranty claim in 2013. Just short of 2 years before the same problem broke the bike. Bootom swing arm pivot point carbon wears away enouph for back wheel to move 1cm either way left or right. Now I am told I am too heavy for the frame! BUT Trek advertises that there is no weight restriction on their frames. Can anyone suggest another manufacturer. My mates all have SCOTT bikes and they have different issues!!! any suggestions??

      D&2001 EPX Terra shark made in Austrailia. Mine has 7-8 k mi.and 8 years of slow to lean crashing’into trees and rock filled creeks, broken bones & torn muscles no carbon probs XTR BUILD $3k 23.5 lb.

  • Roger says:

    I have a Superfly 100, 2010. I read the Bike Rumor complaint about the lateral slop on the swing arm, echoed by Jan here. I checked it and confirmed the same problem – it’s kind of amazing. Mine hasn’t broken yet, but now I notice the rear end sloppiness if/when I ride it. Last year I got a Specialized carbon s-works epic 29er, and I only ride it now; it’s a great ride.
