Steve Stefko’s 2025 Trek Boone, an a la carte build weighing in at 18.6 lbs, setup for the Masters 40-45 National Championships.

Zipp Service Course SL stem (110mm) and Bontrager VR-C aluminum bars (42cm) with a Garmin 1040 stem mount.

The Boone's integrated chain keeper paired with the SRAM Red XPLR 1x drivetrain.

Detail of the IsoSpeed coupler, which provides rear-end compliance on rough courses.

SRAM Red XPLR 12-speed rear derailleur and Force XPLR 10-44t cassette.

SRAM Red XPLR AXS brake levers and shifters.

DT Swiss 350 front hub laced to a Reserve 42mm rim with a 160mm SRAM rotor.

Sad day- Something in the truck rubbed on the seat stay during transit to Nats. Steve sealed it with some heavy duty super glue/epoxy the evening he pulled into town.

Bontrager bottle cage mounted on the seat tube to keep the front triangle somewhat clear for shouldering.

Front SRAM Red XPLR hydraulic disc caliper and 160mm rotor.

Donnelly PDX 33 front tire measuring 36.8mm. Steve runs 27 psi for his 187 lb weight.

Side profile of the Ergon SR Allroad Core Pro Men saddle (size S/M).

Side view of the 110mm Zipp Service Course SL stem with a -6 degree rise.

Steve raced with Magnus in the SM Open category as Steve's elite racing career was wrapping up and Magnus' was just beginning.

Shimano XTR pedals provide the interface for the championship-winning effort.

SRAM Red XPLR 42t chainring and Red cranks.

Reserve 49mm rear wheel with a 24.8mm internal width.

Donnelly MXP 33 rear tire measuring 36.6mm at 28 psi for his 187 lb weight. Both tires are set up with 70ml of Orange Seal Endurance.

Probs oughta get a National Champion colorway for that sticker.
