Top Fuel

The Trek Top Fuel, with 100mm of travel,full-suspension-29ers-wed-tell-our-friends-buy>full suspension bike. The most obvious difference between the two bikes is a switch from a top swing link to a rocker link with floating shock mount. The new design compresses the shock from both the top and the bottom, granting Trek’s engineers more control of the suspension tuning.With a carbon frame weight of 1,900 grams, the Trek Top Fuel is about 50 grams heavier than the Superfly SL, but it’s also stiffer;Like the Procaliber, the Top Fuel uses 27.5-inch wheels for the smallest frame size and 29-inch wheels for the rest. With the 29-inch wheels comes replaces the Superfly FS as the company’s lightest  on the front and rear. The Top Fuel also uses the Control Freak cable system described above and is dropper post-compatible.

Top Fuel 8 用家評語

From: Vince 23

Pros: Not a professional although this bike definitely is. Boosted my confidence 10 fold. This bike along with my tubeless tires gave me a new perspective on trail riding . 

ConsSo far I haven’t had any complaints…

Recommendation: Gave a whole new level of confidence. I love this bike!!!! Worth every penny….


From: TheWVPedaler

Pros: Fast, climbs well, descends like a train on rails, great control, versatile, clean lines, great geometry…

Cons: Will add when I find one!

Recommendation: I have had many bikes and this one takes the cake! I am a better more confident rider on this bike! Id rather hammer out a climb than drop off the side but I am more comfortable now with this bike. Improving on my times on every descent I attack.

Now that we got that out of the way; as soon as Trek dropped the news about the new and improved Top Fuel I had the blinders on. I loved everything I was reading about this bike! The styling was great, the reviews that were out so far were awesome, not to mention the promo videos from Trek. I would say that everyday I was doing more and more research on the bike and with every passing day I wanted it more and more. I was a little skeptical of the Boost setup but I also read all there is out there on it and I was digging that as well. I love the 29er wheels and getting a stronger wheel with widening the hub to allow for a steeper spoke angle to strengthen the wheel impressed me even more!

TREK 2017 MADONE 9.2 技術介紹

IsoSpeed Decoupler

Trek engineers designed a decoupler that allows the seat tube to rotate independently from the top-tube-to-seatstay junction, increasing vertical compliance to twice that of our nearest competitor, without compromising pedaling efficiency. Result: you can ride harder, longer.



Advanced aerospace materials and weight-saving, performance-enhancing technology give 600 Series OCLV the best balance of frame weight/stiffness in the industry.


H2 is the optimal fit to put most riders, including many of our Pro Team athletes, in the right position for power and performance.

KVF tube shape

We’ve optimized our revolutionary KVF tube shape to complement Madone’s ultimate integration, creating a lightweight and super-aerodynamic frame that outclasses every competitor.

KVF Fork

Our slippery fork features KVF aero legs to minimize drag, while the unique molded carbon dropouts reduce weight. The new fork also increases lateral stiffness for ultra-precise handling.

Areo Bar/Stem Combo

Madone’s new bar/stem combo is fully integrated into the frame and features the sleekest, lowest-drag profile ever developed.


Micro-adject Seatmast

The all-new micro-adjust seatmast is lightweight, strong, super aerodynamic, and easy to use. Even a millimeter change in geometry can alter your speed. Dial in your fastest, lowest-profile position ever with the all-new seatmast.


Articulating Vector Wings enclose the leading cables and front brake caliper in a protective shell.


The new direct-mount Madone brakes are seamlessly and beautifully integrated into the frame to cut drag, increase speed, save weight, and add to Madone’s sleek aesthetic.

Invisible cable routing

The brake and shift cables of the most aerodynamic bike are routed through the frame for the ultimate in sleek, aerodynamic performance.

Who is this type of bike suited too? Racers, crit riders, short course triathletes.

MADONE 9.2 Standout-features︰

Aggressive geometry, aero tube profiles, deep section wheels.

Aggressive geometry

The main priority of aerodynamic bikes is to reduce drag and be as slippery as possible in the wind. 85% of resistance a rider needs to overcome is from themselves, so it makes sense to reduce a riders frontal profile as much as possible. As a result, the headtube on aero bikes is short creating a lower frontal profile and having less resistance to overcome. As a general rule the headtube on a medium sized aero bike will be under 140mm, opposed to an endurance bike which will be over 160mm.


Tube profiles of aero bikes push the limits of the UCI regulations of a 3:1 profile, which means for every centimetre they are deep, they can only be three centimetres in length. The goal of an aero bike’s tube profiles is to minimize drag and be as slippery in the wind as possible. To do this tube profiles are long, thick and shaped with a tapered leading edge and sculpted tail. In some instances the ‘tail’ of the tube is cut off which mimics a sculpted tail in varying wind positions.

Integration is a key component of aero bikes. Sometimes it can be hard to know where the brakes of an aero bike are because they are hidden. Many aero bikes will have the rear brake hidden out of the wind underneath the bottom bracket area or hidden with ingenious creations like Trek’s ‘vector wings’. It’s also common to see ‘cut-outs’ on the seat stays, seat tube or fork to seamlessly integrate the brake to the bike.

deep section wheels

The final piece of the aerodynamic puzzle is deep section wheels. Aero bikes will always be paired with deep section wheels to further reduce drag and enhance aerodynamics. Typically these wheels will be at least 40mm deep, sometimes up to 80mm. The downside of running deep profile wheels is the additional weight and potentially difficult handling in windy conditions.

Traditionally road bikes came with a 53T large chain ring and a 39T small chain ring on the front crankset. There has been a steady movement for most bikes towards a ‘mid-compact’ crankset which has a 52T large chain ring paired with a 36T small chain ring or a ‘compact’ set up with a 50T large chain ring and a 34T small chain ring. The smaller ratios create easy-pedaling gears, perfect for slower speeds or climbing. As aero bikes weren’t intended for either of those two things, they often have a traditional 53/39 crankset to cater for high speeds on flat roads. The rear cassette ratio complements the need for speed. An 11-25 cassette is typically used to provide smooth shifting and smaller jumps between gears.

“The new Madone is one of the most comfortable and integrated road bikes on the market, but the fully hidden cables are sure to be a headache in the long run”

Aero road racer with ISO Speed decoupler

You want a race bike that won’t leave your body beaten and battered at the end of the day

Trek’s new Madone is awesome, and a bike I’ve really enjoyed riding over the past few months. The IsoSpeed decoupler is truly an amazing piece of technology, and we’re stoked to see it being adopted in the American outfit’s stable of racing bikes (fingers crossed the Emonda is next). Essentially having two seat tubes, there’s a small weight penalty but we’d say it’s worth every gram for the affect it has on ride quality.
