When Trek announced their Emonda carbon road bike line, they backed up their “world’s lightest” claims with an impressive frame and fork and an even more impressive 10.25lb (4.6kg) complete bike. Now, they’re adding an alloy Emonda ALR option that’s also lightweight yet far more affordable.
To earn the Emonda badge, the frame uses their top-level 300-series Alpha Aluminum that’s been hydroformed into size specific tubes, then welded together using a no-see technique that produces smooth joints that use less material to save weight.
The process is called Invisible Weld Technology, which they say produces stronger, stiffer welds despite using less material. Video, pics and more details below…
Trek told us the unpainted frame is 1050g (56), and a painted fork is 358g w/240mm steerer.
Like the ultralight Emonda carbon models, the ALR uses their H2 race geometry, E2 tapered headtube (standard 1-1/8″ to 1-1/2″) and wide Pressfit BB 86.5, meaning this bike is made to go fast. Other frame details include a braze-on front derailleur mount (no need to add a clamp if you’re getting the frameset) and external cable routing.
We’ve requested a more technical description of the welding process (update as we get it), but the frame is only part of the story. The complete bikes come equipped with built-in extras like the a Blendr stem with integrated light/computer mount, and it has Duotrap S compatibility (their ANT+/Bluetooth 4.0 speed/cadence sensor, sold separately for about $60).
You also get a complete group, so the Emonda ALR 6 with Ultregra gets a full Ultegra group from chain to brakes to cassette and everything else. There are no mis-matched parts or down spec’d bits to cut costs. A full carbon fiber tapered fork completes the package.
The Emonda ALR will initially come in two builds, the “6” with full Ultegra, Bontrager Race tubeless ready wheels with R2 tires, and a Bontrager cockpit with alloy short reach/drop bar and carbon seatpost for $2,249.99. Our local Trek Bike Store says complete bike weight is claimed at 17.25lb (7.82kg).
The Emonda ALR 5 drops down to a full Shimano 105 group with non-series Bontrager tubeless ready alloy wheels, R1 tires and a full alloy Bontrager cockpit for $1,759.99. Claimed weight is 18.77lb (8.51kg), colors will be the gloss black/hi-viz yellow and blue shown here, plus a racing red coming soon.
The frameset shares the same paint scheme as the “6” and comes with an FSA sealed cartridge bearing headset for $989.99. The frames have a lifetime warranty carrying a 275lb rider weight limit.
Just for fun, here’s the companion lifestyle video.
All three models shown here are available now and should hit stores soon. Our sources tell us there’ll also be an Emonda ALR 5 with Tiagra, an ALR 8 with Dura-Ace mechanical and ALR 9 with Dura-Ace Di2 coming soon. That last model suggests they’ll have an electronic-only frame, too, since these first models only have external cable routing. At the very top, in terms of light weight anyway, will be the ALR 10 with a full SRAM Red group.
