Upcoming events

The new Trek Domane

Trek has announced an update to its popular endurance range, revealing new Domane SLR and SL models that boast greater versatility, integration and improved aerodynamics.

Wind tunnel-tested tubing will, according to Trek, save riders a minute per hour. The sculpted front end of the bike certainly looks lifted straight from the Madone and the new straight fork is said to help the bike cut through the air more efficiently. New integrated cable routing should also help save more watts. Oh, and yes it’s disc brake only.

Trek Domane: adjustable IsoSpeed

As you might expect, Trek’s front and rear IsoSpeed makes a return on the new SLR and SL models, but the former is also endowed with the adjustable top-tube IsoSpeed technology that was launched with the Madone last summer.

The slider now sits underneath the top tube and the gives a claimed 27 per cent increase in compliance as well as allowing riders to fine-tune compliance to match the terrain.

Trek Domane: the most versatile Domane yet

While the Trek Domane of yesteryear was content to exist as a performance road and cobble bike, the new model sets its sights on an even rougher terrain – gravel. The takeaway message from the updated range is that Trek has prioritised versatility, continuing the push towards ‘one bike to rule them all’: the Domane is now a bike capable of ripping on the road and flying off-road at just a change of the tyres.

Enormous tyre clearance and hidden fender mount

While the new Domane will come equipped with already sizeable 32mm Bontrager R-series tyre, the bike now has the space to swallow a whopping 38mm tyre as standard, or a 35mm when fenders are fitted. The guards can be attached to the new hidden rack mounts on both the front and rear of the bike and there’s also an integrated light mount on the underside of the saddle.

Hidden Haribo

However, in what I’m going to term next-step versatility, the new Domane also has a hidden down tube compartment beneath the bottle cage. It’s almost a direct copy of Specialized’s SWAT box on the brand’s mountain bike range, but it’s the first time I’ve ever seen a road frame using such technology. It might be as simple as just having a hole in the frame to store your tools but in my opinion anything that removes weight from your jersey is a great idea. A BITS tool roll will also be available to keep the inside of your frame protected.

The other side of the trap door….

Following hot on the heels of the gender-neutral Specialized Roubaix, it’s interesting to see Trek become another brand to eschew female-specific geometry with its new bike. The Domane now exists as a unisex platform available from a size 44 with a greater number of colours available. Trek’s ‘Endurance Fit’ is used across the models as standard but a H1.5 fit option is available from Project One, Trek’s high-end customisation tool.


Trek Domane: first ride

Trek Domane

With a decent mix of climbs and descents – both on and off road – Trek’s test loop in the wooded hills of Galzignano Terme in Padua was sure to provide a decent shakedown for the new bike.

As I’ve found with previous Trek models, I felt quite stretched out on the bike, like the top tube is long or the seat quite laid back – but it was nothing a bit of fiddling couldn’t fix.

The first 10km of the loop covered close to 400m of climbing and the Domane handled it without missing a beat. Despite the IsoSpeed flexing away there’s no discernible loss of forward momentum and the bike responded very well to rider input.

On the fast and steep gravel roads the bike felt comfortable, although there were several punctures among the group and a rattling down-tube storage unit needed tightening (I used the multitool hidden in there).

For a long-term test I’d swap out the Bontrager R3 tyres for something a bit wider and more substantial, but off the back of the initial rides I will be excited to stuff that down tube full of Jelly Babies and see where this bike can take me.

As with a lot of recent ‘endurance’ bikes, it’s interesting to see how far they bite into ‘adventure’ bike territory. Take the new Specialized Roubaix as an example, there’s no doubt that’ll chomp into the Diverges remit and I suspect the Domane might well do the same to the Trek Checkpoint.
