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
