2015 Trek Madone Review with Pictures - BUMSTEADS BICYCLES

Trek Madone Range Has Been Stripped Down to Just Five Bikes for Model Year 2015.

We’ve covered the Madone is detail previously, most recently when we shot Jens Voigt’s 7-Series machine for the 2014 Tour de France, and last year when we reviewed the now-defunct Madone 5.2.

Madone 7-Series

The 7-Series frame remains the same for 2015, so there’s the aero-profiled truncated Kammtail tube profiles, BB90 bottom bracket (which also features on the Emonda) and direct mount brakes, with the rear brake hidden from the wind behind the BB.

The Madone 7.9, dressed in Shimano Dura-Ace Di2 and Bontrager Aeolus 3 wheels, is the top-of-the-range model, and it’s also available as a WSD option. Otherwise there’s the Madone 7.7,  with mechanical Shimano Dura-Ace and Bontrager Race X Lite Tubeless Ready wheels. UK prices for the 2015 Madone 7-Series bike are to be confirmed.

Madone 2-Series

Leap down to the Madone 2-Series range and there are two aluminium bikes: the Madone 2.5 and the Madone 2.1.  But why, if the Madone is now Trek’s high-end-only, out-and-out aero race bike, keep the alloy line-up?

“We still needed a nicely-specced, nicely-engineered alloy road bike that was still higher end than the 1-Series bike,” says Garrison. “Rather than create an entirely new platform, we kept the Madone 2-Series. It’s a really nice bike which got a facelift last year – it rides a lot better than you think it will. It’s pretty light and while it’s certainly not as aero as the 7-Series, it’s still got a lot of the KVF tube shaping. If it ain’t broke, don’t fix it.”

Of the two 2-Series bikes, the Madone 2.5 comes with a mix of Shimano Ultegra/105 components, Bontrager Race Tubeless Ready wheels and Bontrager finishing kit, while the entry-level Madone 2.1 uses mostly Shimano 105 components.

While not part of the Madone range, Trek’s 1-Series aluminium bikes remain in the 2015 line-up, with three bikes – the 1.1, 1.2 and 1.5. Like the Madone 2-Series, the 1-Series received a facelift last year, with a new hydroformed frame introduced, so the chassis remains the same, but the colors have been updated.

Pre-Tour de France Release: 2015 Trek Emonda SLR 10

Lightest Road Bike Ever (10.25 lbs!)— Only From Trek

In order to achieve this feat, Trek used every form of technology available. Finite Element Analysis, strain gauge instrumentation, and a custom designed cornering computer model all contributed to the lightest production road bike available on the market.

“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 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.

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)

2015 Trek Fuel EX 27.5 (Available Now!) — Remedy 29 Carbon Scheduled to Debut Next Year

2015 Trek Mountain Bikes with RE:ACTIV Technology

Trek partnered with Penske Racing shocks to improve the dampers found in the Dual Rate Control Valve (DRCV) shocks found on its Fuel, Lush, and Remedy bikes. Penske Racing has a long history building shocks for some of the most demanding motorsports, including F1, NASCAR, and World Touring car racing as well as other disciplines such as ATV and motocross.

The new technology is dubbed Re:aktiv. At the heart of the system is a new damper stack that allows faster low-speed-compression reaction time while providing a firmer platform for pedaling. The new shocks will retain the DRCV air spring, and will continue to be produced by Fox Racing Shocks. The DRCV shock has two air chambers. On smaller bumps or smooth terrain, the shock uses only the primary chamber. Larger hits that force the shock shaft to travel halfway through its stroke open an auxiliary chamber that increases the overall air volume. Trek claims the DRCV offers the lively feel of a shock with a smaller air spring, but provides the plush bump absorption of a larger air spring. Combining that technology with a firmer platform to pedal against, it says, will result in a bike that will perform just as well whether you’re pedaling over rough terrain or letting the suspension (and gravity) do the work on a descent.

Jose Gonzalez, Trek’s director of suspension design, explained that the new damper optimizes the suspension by keeping the shock at the sag point (previous-generation shocks tended to sit closer to the mid-point of the stroke). The benefits of this are twofold: It holds the bike closer to the true geometry of each model and allows the damper to react quicker and return to its optimum position sooner. As a result, the bikes pedal more crisply in all three shock modes, Climb, Trail, and Descend.

Trek also linked up with Push industries to supply air volume reducers for its DRCV shocks and forks. The parts are available directly from Push and allow riders to tune the suspension to their liking by altering the factory air spring rate. These small spacers are available in multiple sizes so you can make incremental changes in a fork’s or shock’s air spring rate.


New Remedy 29 Carbon with Boost 148

The Remedy 29 gets a makeover for next year with the addition of carbon-frame offerings. Most of the bike remains unchanged, with geometry and spec carrying over from the current models. The biggest change is at the tail of the bike, with the introduction of Boost 148. Trek increased stiffness laterally in the wheels by partnering with SRAM to offer a hub that is 6mm wider at the axle ends and pushes the hub flanges out by 3mm each. Trek claims this will create better triangulation and even out spoke tension, and that the 29-inch wheels will ride closer in stiffness to their smaller counterparts. The Boost 148 design adds clearance to the frame for tires as large as 2.3 inches, while also keeping chainstays short and chainline in check for proper shifting performance. For riders using a single-ring drivetrain—the system will work with a double setup too—SRAM developed a spider that keeps the centerline of the ring in proper alignment with the cassette so shifting performance is unaffected. Trek and SRAM designated the system as “open source,” so the design is available to any manufacturer.
