Listen up hammerheads: today Trek announced an updated Top Fuel — their full suspension XC bike — and the Procaliber SL, a hardtail featuring their IsoSpeed decoupler.

Iso-what-so?

If you follow road cycling at all, you may be familiar with Trek’s IsoSpeed decoupler from their Domane line of bikes. Basically, the seat tube is decoupled from the rest of the frame, which allows for a small degree of movement. How much movement? According to Trek, the Procaliber SL gives the rider up to 11mm of vertical compliance.

That may not sound like very much, but anything that can reduce fatigue during a race is going to allow you to ride faster and longer. Trek claims that the Procaliber SL is a whopping 70% more vertically compliant than the existing Superfly hard tail.

For fans of the Superfly, worry not: Trek is keeping the Superfly in their line for riders who want the stiffest, lightest bike possible. A medium Procaliber SL frame is about 100g heavier than their uber-light Superfly SL. The trade off in weight for comfort is one that their riders are willing to make, according to Trek.

The Procaliber SL has also been updated to all the latest and greatest MTB tech with Boost spacing front and rear, Shimano Di2 compatibility, and even the option to run an internally-routed dropper post. The small size will be rolling on 27.5″ wheels while the medium and large sizes get 29″ hoops.

Available as a frame-only for $2,630 or three levels of complete bikes, the Procaliber SL 9.7 starts at $3,680 and the 9.9 maxes out at $8,400.

Top Fuel

The Top Fuel is taking over duties for the current Superfly FS. Highlights of the revamped bike include a revised suspension layout for better shock tuning, Boost spacing front and rear, Di2 compatibility, and the ability to run an internally-routed dropper.

As with the Procaliber SL, the Top Fuel gets 27.5″ wheels on the small frames, with larger frames getting 29er wheels. Frame weight including all hardware, paint, and shock is a claimed 1,900g!

The Top Fuel carbon frame set will set you back $3,470 and the remaining range starts at a more accessible $2,090 for a complete aluminum bike. From there you get numerous options all the way up to the $9,450 Top Fuel 9.9 SL.
