Summary
The Trek Procaliber is a cross-country bike that excels with its IsoSpeed decoupler, providing a more compliant ride, especially when seated. It's praised for its lightweight construction, efficient power transfer, and modern XC geometry, though some note limitations in steering precision and the effectiveness of IsoSpeed when standing. The bike is often compared to the Trek Superfly and BMC Teamelite for its performance in the cross-country category.
IsoSpeed decoupler for added comfort
Lightweight and efficient power transfer
Modern XC geometry
IsoSpeed benefits limited to seated riding
Poor steering precision in some models
Mixed opinions on tire performance
The Procaliber with its fancy IsoSpeed is a clever approach to providing comfort in the otherwise harsh world of racing hardtails.
It’ll also blur the lines between choosing a dually or hardtail, because when it comes down to it, if the terrain suits a hardtail nothing beats a carbon 29er when you’re really hammering on the pedals.
Unfortunately the killer looks and many clever details don’t make up for the poor steering precision of the Trek Procaliber 9.9 SL.

The Procaliber uses Trek’s Smart Wheel Size arrangement, meaning the …
IsoSpeed is successful in taking the sting out of the trail when seated.
Stunning frame construction.
Lightweight parts.
Not to be confused as a suspension bike, it's still a hardtail.

Impact-smoothing super-light racer, but needs fatter tyres and pedalling bounce can be irritating. Buy if you like your greyhound hardtail with a side order of comfort, and are prepared to make a kit tweak or two
Svelte, contemporary frame, isospeed pivot smooth buzz, rapid ride
Smoothing tech can be a double-edged sword, needs fatter treads to get the most from it

The Procaliber will give you all the efficiency and fun that you need

Jul 2015 · Trev Worsey
XC race bikes are traditionally an acquired taste, steep, uncompromising and brutally efficient. Any thoughts of comfort and fun are secondary to milking out every watt of energy from a rider who resembles nothing more than a huge set of lungs and set of shaved muscular legs. So imagine our surprise when we took to […]

Turning its focus on its cross-country racing bikes, Trek made some significant changes to its XC line. Most notable is the introduction of the Isospeed coupler in to the Procaliber hardtail line. - Mtbr.com
