Everything you need to know about Trek’s radically new, short-travel XC race bike, the Supercaliber

The Supercaliber is a best-of-all-worlds XC racing bike with a unique, structural suspension design and two water bottle mounts. Not quite a hardtail and not just a full suspension bike. Here’s the scoop…

The 2020 Trek Supercaliber cross country race bike.

Supercaliber delivers the light-weight and efficiency of a hardtail plus the control and traction of a full suspension bike. It’s the perfect solution for XC racers who want to hammer on climbs and sprints, and also keep speed through the rough stuff.



ISOSTRUT SUSPENSION DESIGN

The Supercaliber IsoStrut is a frame-integrated shock which was created in partnership with FOX suspension engineers. The system delivers 60mm of damped, tunable rear travel. IsoStrut is encased in a structural stanchion that prevents twisting, flex and deflection. This unique design gives the bike the exceptional pedaling efficiency and removes the need for excess suspension linkages – along with the weight and excess lateral motion that typically come with them.

Trek went through four years of development, prototyping and riding to perfect the IsoStrut technology. They settled on an air spring because of it’s wide tuning capabilities. They also wanted the damper to have a lockout system and damped control on the trail. The main pivot is shifted forward to optimize pedaling efficiency and bump performance. Lastly, the entire structure needed to be strong and reliable. The Isostrut system features fork-style bushings with wiper seals and a carbon fiber carriage. The bow shaped seatstays are pivotless. The early prototypes can be seen below.



BUILT TO RACE

Did we mention it has two water bottle mounts? No, okay, well now you know. The Supercaliber is available in four complete models with six sizes on offer. Each is equipped with an OCLV Mountain Carbon frame with Straight Shot down tube and Knock Block, a SRAM 1×12 drivetrain and Bontrager Kovee carbon wheels with Rapid Drive hub internals for almost instant stomp engagement.

‘This has been that dream bike that I always wanted, but never existed until now,’ said Trek Factory Racing’s Jolanda Neff. ‘I’ll be racing nothing else from now on.’

Trek Factory Racing XC has raced Supercaliber on the World Cup circuit this year and will continue to compete aboard the bike for the remainder of the season and into next.

The Bontrager Kovee MTB wheels are backed by the Bontrager Carbon Care Wheel Loyalty Programme meaning if they’re damaged within the first two years of ownership, Bontrager will replace or repair them for free. All Supercaliber models have a 100mm fork. Since this is a race bike Trek went for 29˝ wheels on all frame sizes along with room to carry two water bottles in the main triangle. The Supercaliber will be rolling into Trek retailers from today and is also available for customisation through Trek’s Project One program.

FAQ

What about riders who still want a true hardtail? Procaliber is still available in 9.6 and 9.7 models. Procaliber SL is still available as a frameset for riders who want to customize the ultra-light build of their dreams.

How do you set up the suspension? Much like any other shock. Use the Trek Suspension Calculator as a starting point for psi and rebound settings.  We’ve even made setting rebound easier by etching numbers on the dial so you always know what setting you’re on. Adjust psi for the correct sag measurement, then go ride, making further adjustments as necessary. Larger or more aggressive riders can use the included IsoStrut volume spacers to adjust the spring volume for a more progressive feel or better bottom-out resistance.

Is IsoStrut user serviceable? Yes. IsoStrut maintenance is much like any other shock. See service guide for details.

What is the max fork travel? 120mm, or 531mm axle-to-crown.

Is it compatible with cranks with 30mm spindles? Yes.

Are there ISCG mounts? Can I run a chain guide? There are no ISCG mounts because Supercaliber is a weight-conscious XC bike, and ISCG tabs make the frame heavier. We will offer an aftermarket chain guide (W584677) that clamps to the BB shell for riders who want additional chain retention security.

Is it compatible with 2x drivetrains? No.

What is the max tire size? 29×2.2”

Is it compatible with 27.5” or 27.5+ wheels and tires? No.

What is the max chainring size? 36-tooth.

When will new Supercaliber be available in Project One? Spring 2019

Why does the Small size have 29-inch wheels? What happened to Smart Wheel Size? We still believe Smart Wheel Size makes sense for most cross country hardtail riders where seated pedaling takes priority. Smaller 27.5” wheels are easier for shorter riders to handle, and they allow those riders to easily achieve an efficient position on the bike for producing power. However, most elite-level racers are willing to trade the benefits of more proportional wheels for the ultimate momentum-preserving speed of 29-inch wheels.
