2015 Trek Endurance/Race Bike: Domane Pictures

Trek's New Domane Models Include 6 Disc-equpped Bikes and 11 Rim Brake Bikes

"Disc brakes on the Domane make sense because there's a growing group of people who are using bikes like this for more off-road adventure riding on gravel roads or smoother bridleways, so there's a growing demand in the market for a disc brake road bike."

The Domane uses Trek's IsoSpeed coupler at the seat and top tube junctions to separate bumps and vibrations from the rider and create a suspension effect.

Trek Bicycle Superstore said this about the 2015 Domane 6.9:

"Trek's Domane was in secret development for three years. Then, they gave it to Fabian Cancellara to race on. It won. Trek considered every imaginable factor of frame construction to arrive at the perfect balance of speed, stability, and comfort. One ride and it's clear, they nailed it.

Made from Trek's 600-series OCLV carbon, this feathery light rocket boasts a huge bottom bracket and optimized tube shapes to maximize your pedal power. Your power is transferred through Shimano's Dura-Ace Di2 22-speed components, hydraulic disc brakes, fast Bontrager Affinity tubeless-ready wheels, and a carbon fork, post and bars to make this a purebred racing machine built for winning. And it has genius ideas like the IsoZone seat tube decoupler and IsoSpeed fork that make it comfortable and a dream to ride."

Trek Domane 6.9 Disc Long-Term Ride Review

Better than the standard Domane in every way

-Article and Photos from Cyclingnews.com

Road disc fans were rightfully excited about Trek's recent release of the new Domane Disc. After nearly two months of testing, however, we can now say that this latest version isn't just a standard Domane with disc brakes tacked on; it's better than the original in nearly every way.

If your ideal day in the saddle is several hours long across a variety of road surfaces and with lots of elevation changes, you'd have a tough time finding something better suited than this.

That the Domane Disc offers better braking performance than the standard Domane comes as no surprise, especially given Trek's decision to go with Shimano's superb (and highly refined) R785 hydraulic setup. As we've experienced in the past, there's fantastic power on tap with minimal hand effort along with a positive initial bite that's far from grabby or overly abrupt.

Even better, that power is exceptionally easy to control with excellent lever feel and no discernable fade even on long descents, plus the performance is unflappably consistent with rain, heat, and mud having minimal effect. We did experience a bit of noise when the rotors got hot along with a bit of lever rattle (more on that later) but otherwise, there's little to complain about.

Quite tellingly, at one point during testing we climbed back aboard another test bike with broken-in Mavic Exalith 2-treated wheels – arguably the benchmark for rim brake performance – and the difference was akin to driving a car with disc brakes versus drums.

Even so, it's the ancillary changes that go along with the move to disc brakes that have us so excited about the Domane Disc – namely, the switch to thru-axles at both ends and the increased tyre clearance.

The standard Domane with its quick-release dropouts is no slouch in terms of frame stiffness – and in fact, Trek confirmed that it's nearly on par with the edgier Madone for drivetrain efficiency and actually even better in terms of front-end stiffness. Not surprisingly, then, we couldn't detect any difference in rear-end stiffness as a result of the stouter connection.

We did, however, notice a slight boost in handling precision up front, particularly on bumpier surfaces such as crushed gravel and washboarded dirt roads. Moreover, the more precise fit of the thru-axles relative to open dropouts meant that we could repeatedly remove and reinstall both wheels without inducing any pad rub on the rotor.

Given the company's global market and various national safety guidelines, Trek officially can only officially approve the Domane Disc worldwide for use with tyres no wider than the included 25mm Bontrager treads. However, we found ample room for 30mm-wide Challenge Strada Bianca open tubulars and their effect on the bike's ride was revelatory.

As expected, the bigger tyres produced immense cornering grip along with improved drive and braking traction on looser country roads. While they of course added some weight, they also tempered the one major criticism we have on the otherwise excellent Domane platform: the disparate ride quality between the front and rear ends (and at an actual complete weight of just 7.52kg/16.58lb in stock form without pedals, it's a highly capable climber with some leeway on the scale).

Trek's novel IsoSpeed seat cluster pivot is just as fantastic as on the standard Domane, turning standard pavement into glass and flattening even washboarded dirt roads into something that's far more tolerable. Combined with the well tuned carbon frame, the Domane Disc's rear end is exceptionally good at squelching vibration while also devouring bigger bumps – a trait no endurance bike from other companies has managed to achieve to this degree.

However, the front end rides notably rougher because there's no IsoSpeed-like mechanical device up there to even things out. The higher-volume tyres go a long way toward accomplishing that, and it's a pity Trek doesn't include them as stock equipment. If you're careful about which wide-profile tyres you choose, the bike actually even rolls across the road faster than before, even at substantially lower inflation pressures.

Otherwise, the standard Domane traits carry over, including the awesome stability at speed, surefooted cornering characteristics, and comfortable riding position. The front end can admittedly feel a bit floppy when moving more slowly, though, and tighter corners require a bit more conviction to rip through given the long wheelbase and slack angles.

We're willing to accept those quirks in trade for the incredibly confident high-speed manners, however, and even the super-tall front end can be largely tempered by swapping to a shorter headset cover and a more aggressively angled stem.

Frame: Progressive design, slick aesthetics

While the front triangle of the Domane Disc differs little from the standard OCLV 600-Series carbon Domane save for the altered internal cable routing setup, the rear end and fork are totally new.

Trek mounts the rear brake caliper to the chainstay so the seatstays now reach further rearward to make room before arcing back down to meet the dropouts. Those dropouts are also far meatier than before in order to make room for the bulkier thru-axle hardware and since there's no conventional rear brake mount required, the seatstays go bridge-free.

Otherwise, the standard Domane features carry over, such as the tapered 1 1/8-to-1 1/2in front end, the 90mm-wide BB90 bottom bracket shell with directly pressed-in bearings, an integrated chain catcher, keenly hidden mudguard mounts, and a pocket in the non-driveside chain stay for Bontrager's DuoTrap wireless speed and cadence sensor.

Up front, Trek retains the standard Domane's radically curved fork, which the maker claims offers more bump absorption than a more conventional setup (and we'd agree, at least to a point). As with the frame, the dropouts are substantially bigger than on the rim brake variant in order to accommodate the bulky convertible thru-axle dropouts although some of that visual mass is concealed by the integrated post mount brake caliper tabs.

Equipment: Fantastic Shimano hydraulic/Di2 group and solid Bontrager gear

Our top-end Domane Disc 6.9 model came loaded to the gills with premium equipment that included a Shimano Dura-Ace Di2 electronic transmission mated to R785 hydraulic levers and brake calipers, new Bontrager Affinity TLR Disc aluminium clincher wheels, and a variety of carbon and aluminium Bontrager finishing kit.

As we've noted on previous occasions, there's little negative that can be said about the unflappable Dura-Ace Di2 transmission – push the buttons and the chain moved across the various cogs and chainrings with remarkable speed and precision, all with but the slightest wiggle of your finger. And as we've already mentioned above, the associated R785 brakes are exactly what fans would want out of a high-end hydraulic road disc system.

Our complaints are fairly minor and limited to insufficient tactile feedback on the shift buttons and some persistent rattling from the levers on rough roads. We were able to eliminate most of the latter with a couple of tiny bits of thick tape applied just inside the lever body but we'd obviously prefer that Shimano iron out this bug from the factory.

Otherwise, we were already quite familiar with most of the excellent Bontrager finishing kit, such as the cushy Race X Lite IsoZone carbon bar, the reliably sturdy Race X Lite forged aluminium stem, and the light-yet-comfortable Paradigm RXL saddle.

We were pleasantly surprised, however, by the Affinity Elite TLR Disc wheelset. Though not especially light at just over 1,600g per set, the 17.5mm-wide (internal width) aluminium rims provide a reasonably spacious foundation for wider tyres and they've proven impressively solid with no truing required despite repeated bashing on less-than-ideal roads. Time will tell if the latest incarnation of Bontrager's house-brand hubs will hold up (the company has once again moved away from DT Swiss).

Potential buyers should make note that the Domane Disc's front and rear thru-axle dimensions are shared with mountain bikes so you'll also be able to swap in many 29er wheels, too.

Bottom line: Awesome long-distance cruiser

All in all, we found the Domane Disc 6.9 to just one component away from being a wickedly capable platform for eating up long stretches of road – any road, as it turns out. We love it as is but upgrading to high-performance, higher-volume tyres makes the bike truly exceptional.

Five Ways To Stay Steady During Hard Accelerations

Get The Most Out Of Your Acceleration By Following Five Easy Tips

1. Firmly grip the handlebar drops slightly lower in the bend than normal (not quite halfway between the deepest part of the curve and the end of the bar).

2. Keep your elbows slightly bent to help you hold a straight line.

3. Pull evenly backward and down on the handlebar with every stroke.

4. Don't hold your breath -  a common mistake during sharp efforts, even among experienced riders.

5. Keep your head up - another frequent error in technique, because it feels natural for some reason to drop your chin

WORLDS Lightest Bike Frame from Trek - Brand New Emonda — Only 10.25 Pounds!

The Engineering Principle Was Simple — Cut Weight, Increase Stiffness

While the principle was simple, the process was anything but. 30 months of pro-rider feedback, strain gauges, accelerometers, and countless iterations of geometry and lay-up prototypes all contributed to the lightest production road bike available on the market.

To make this happen, Trek threw every piece of technology at the process: Finite Element Analysis, strain gauge instrumentation, and a custom-designed cornering computer model. Trek Factory Racing athletes and pro riders performed iteration after iteration of ride testing to determine the right carbon layup and ride characteristics for each Emonda frame size.

“We have the resources to build a complete bike system. Let’s use that advantage to look at every aspect of the bicycle and how each component interacts with all the others,” said Trek road product manager Ben Coates. “Once we covered the basic bike functions, we focused on every minute detail. Every decision was based on what was the overall lightest option for the system.”

Trek built up the SLR 10 with Tune Skyline tubular rims, MIG45/MAG150 hubs and Komm-Vor Plus saddle, a SRAM Red 22 group with ceramic bearings, a Cane Creek AER headset, Jagwire's new sectioned housing, Vittoria Crono CS 22c tubulars, and Bontrager XXX integrated bar/stem and Speed Stop direct-mount brakes.

For the shape of the XXX bar/stem, which has a 129mm drop and 93mm reach, Trek consulted a variety of riders from pros to everyday Joes, Coates said.

"We found that for the vast majority of riders, the variation in bar rotation is very small," he said. "A few guys, like Jens Voigt, have their bars really rotated. But for the most part, it is the lever position that dictates how the bar feels."

Now Trek has three road bikes: the Domane endurance bike, the Madone race bike and this new Émonda climbing machine. When BikeRadar asked for an apples-to-apples comparison on how the latter two compare, Coates declined to give specific numbers, but said they are quite similar in stiffness and compliance.

"In bench tests they are essentially the same," Coates said. "The Madone has a stiffer head tube, but it is not as stiff in the chain- and seatstays. The compliance numbers are virtually the same."

The rest of the bike breaks down like this:
  • Émonda SLR fork (280g), frame hardware (30.5g)
  • Bontrager XXX Integrated bar/stem (216g)
  • Bontrager SLR Ride Tuned Carbon seatmast cap and ears (119g)
  • Cane Creek AER upper headset assembly (18g)
  • FSA Super Light headset lower bearing (17.8g)
  • Bontrager Speed Stop brakes (232g)
  • Stock SRAM RED 22 drivetrain (1455g)
  • Bontrager ceramic BB bearings (62g)
  • Tune headset spacer (1.2g), Tune Komm-Vor Plus saddle (83g)
  • Tune wheelset (MIG45 front hub, MAG150 rear hub, Skyline carbon tubular rims, Sapim CX Ray Spokes (886g)
  • Tune Skyline U20 skewers (27g)
  • Tune Gum Gum expander plug and headset top cap (15g)
  • Vittoria Crono CS tubulars (360g)
  • Bontrager lightweight grip tape with bar end plugs (34g)
  • Jagwire Road Elite Link cables and housing (125g)
