The Trek Checkpoint ALR 5 Gen 3 2027 tops the ALR range with SRAM Apex XPLR wireless 1x shifting, on the same proven aluminium platform.
WHO THIS BIKE SUITS
You want SRAM's wireless AXS shifting without paying for a carbon frame.
You want the simplicity of a 1x drivetrain — no front derailleur to think about.
You want the best the ALR platform offers.
IF YOU'RE LOOKING FOR SOMETHING DIFFERENT
If wireless shifting isn't a priority, the ALR 4 covers hydraulic brakes and a wide-range cassette for less. If you want IsoSpeed comfort and a carbon frame, look at the SL 5 AXS instead.
WHERE IT SITS IN THE RANGE
The ALR 5 is the top of the ALR range — same aluminium frame and carbon fork as the ALR 3 and 4, with SRAM Apex XPLR wireless 1x shifting as the standout upgrade.
Full Checkpoint range: ALR 3 — ALR 4 — SL 5 AXS — SL 6 AXS — SL 7 AXS.
HOW IT RIDES
The Checkpoint's Gravel Endurance geometry keeps you upright and comfortable over long days, with a wheelbase that feels stable and planted on loose surfaces. The ALR frame doesn't have the SL tier's IsoSpeed decoupler, but the carbon fork and generous 42mm tyre volume already take the edge off rough gravel — this is a genuinely capable, confidence-inspiring platform even at the top of the ALR range.
Shifting
SRAM Apex XPLR AXS removes cables entirely and gives a genuinely wide single-chainring range for gravel climbing — a real step up in shift feel over the ALR 4's mechanical/hydraulic-cable setup.
THE FINAL WORD
The Trek Checkpoint ALR 5 Gen 3 2027 is as far as the aluminium platform goes. Come in and we'll help you weigh this against stepping up to the carbon SL 5 AXS.
