Building on it’s IsoSpeed equipped predecessor’s comfort and the modern geometry of the short-travel Supercaliber, the all-new Trek Procaliber hardtail gets all the right updates. Modern geometry, cleaner cable routing, and improved steer-ability make it faster than ever.
What’s new about the 2021 Trek Procaliber?
The geometry’s the biggest change you’re likely to feel. Based almost exactly on the Supercaliber (which has 60mm of unique IsoStrut rear travel), the new Procaliber has:
- 68.75º headtube (0.75º slacker)
- 8mm longer reach across all sizes
- 432mm chainstays (3mm shorter)
- 72.75º seat tube (1.65º steeper)
Here’s the full geometry chart:
And all six sizes, from Small through XXL roll on 29″ wheels now, so all sizes roll faster. And it gets a shorter offset fork to increase trail for more stability.
The cable routing runs everything through full length tubes, all through the downtube, and only has what you need: Rear derailleur, rear brake, and dropper seatpost.
The Knock Block headset now allows for a wider 62º turning radius per side (up from 58º). So, those slow speed maneuvers and tight, twisty corners will be easier to negotiate. Not only does this protect the controls or fork crown from cracking into the top and down tubes during a wreck, Trek says it also keeps the cable from getting yanked too hard.
Theoretically, we’re thinking this means you could run slightly shorter hoses and cables for a cleaner (lighter) look without needing all the extra to accommodate excess bar spin.
There’s also more tire clearance, fitting up to 29×2.4″ treads inside the frame. And those tires com setup tubeless out of the box with TLR strips, valves and sealant.
As for the IsoSpeed decoupler, it carries over unchanged. It creates a pivot point between the seat tube and top tube, with flex designed into the seat tube. This gives the rider more compliance when seated without giving up any lateral rigidity.
It means you lose any of that bump-damping comfort when you stand up, but at least you’ll be able to power through the rougher stuff in a more efficient position than on a standard hardtail.
