First Look: Trek Emonda SLR Disc

RELATED: How to Watch the Tour de France

For 2018, Trek built on their philosophy of lightweight-for-all with two new models: the SL, a price-conscious model based on the current (2017) Émonda SLR and built with 500series OCLV carbon that supersedes the current introductory S models; and a brand-new-from-the-ground up SLR that shaves weight and offers incredible ride characteristics for any bike, let alone one so light. Both variants will be available in rim or disc models. 


The SLR is Trek’s flagship offering in the line. It will be available in H1, Trek’s longer, lower, race oriented fit, and H2, with a slightly shorter reach than the H1 and a taller head tube. Both bikes will be constructed of Trek’s proprietary 700 OCLV carbon. Weights for both frames are a claimed 640 grams (Rim, H1, size: 56cm) and 665g (Disc, H1, size: 56cm).  For comparison, the previous Émonda was 690g.  

All the proprietary tech of the current Émonda is retained, including the E2 head tube (which maximizes strength without adding weight) BB90, a ride-tuned seatmast and Duo Trap speed/cadence sensors in the left chainstay. The rim version relies on Bontrager Speedstop Pro brakes directly mounted to the frame in traditional fork seat stay positions.
The only difference between the disc and rim frames is co-molded dropouts with aluminum inserts, to carry the disc-mount style calipers and to capture the thru axles. Rear spacing is 142×12 while the fork sees a 12mm thru axle.

The Émonda will be available in both men’s and women’s models with the only difference being touch points and paint schemes. Riders who want a truly custom bike can take advantage of Trek’s Project 1 program to pick their own paint job and component spec. The SL model with H2 geometry is available in 44-62cm frames.  SLR with H1 runs  50-62cm.

Trek’s aim was to craft a purpose-built all-around road bike with a simple goal: Improve ride quality and make the lightest lighter. It also needed to hold up, with no rider weight limit and a lifetime warranty.  

To that end, they used computer modeling to identify ideal tube shapes. As OCLV continues to evolve, the carbon fiber pieces are getting smaller and more optimized, which allows Trek to focus on ever-smaller areas of the frame and continue to pare down weight. Trek claims they made hundreds of working model frames before they arrived at the final product.
