Well ahead of the coming ‘cross season, the Trek Crockett has gotten a serious upgrade. Starting with a new aluminum tubeset borrowed from the Emonda ALR, the Crockett is still built to be a versatile race bike, but it has some interesting new features – like a T47 bottom bracket.
We’ve heard plenty of rumors lately that Trek was planning to add T47 bottom brackets to some new bikes, and this confirms it. The Crockett seems to be the first bike to use the new-ish standard which was originally pioneered by hand built framebuilding community. The threaded standard runs a bottom bracket shell that is almost the same internal diameter as PF30 BB shells, but uses 47x1mm threads to hold the cups in place rather than a press fit.
On Trek’s T47 BB, it uses an 86mm wide shell for plenty of frame stiffness, and it will work with most common cranksets provided you have the right bottom bracket or adapter.
Moving to a new tubeset similar to the Emonda ALR, the Crockett runs 300 Series Alpha Aluminum with Trek’s Invisible Weld Technology. The resulting frame comes in at a claimed 1325g for a painted 56cm frame.
Built with clearance for up to 700c x 38mm tires, the Crockett is still destined to be a race bike with Cross Race Geometry developed in part with Katie Compton and the the Telenet Fidea CX team.
However, to make sure the bike is as versatile as possible in the off season, it regains hidden fender mounts allowing you to run full coverage fenders for training or commuting.
The frame also features front and rear 12mm thru axles, flat mount disc brakes, and an integrated chain catcher for 1x drivetrains. Cable routing is internal with Trek’s Control Freak system, and the bike is now geared only – no more Stranglehold dropouts for single speed use.
Sold as the Crocket 4 ($1499, or Crocket 5 ($2299) complete, the frameset will also be available with the same OCLV carbon fork. Complete bikes include Bontrager Affinity TLR wheels with a 21mm internal width, flat mount brakes (mechanical 4, hydraulic 5), and a SRAM 1×11 drivetrain. Available now.
