A gravel bike for riders taking their first steps off the tarmac, with a lightweight aluminium frame, a carbon fork and an 11-speed SRAM Apex drivetrain, plus room for wider tyres as their routes get rougher.
Overview
The Checkpoint ALR 4 is built on a 300 Series Alpha Aluminium frame with a tapered head tube and a full carbon fork. It aims to feel responsive on chunky gravel roads and smooth when you link them together on tarmac.
The build covers the essentials: a 1x11 SRAM Apex drivetrain with an 11-42 cassette, Tektro mechanical disc brakes with 160 mm CentreLock rotors, and tubeless-ready Bontrager Paradigm wheels with GR1 Team Issue 700x40 mm tyres. The frame also has integrated frame bag mounts, rack and mudguard mounts, and clearance for wider tyres.
In Matte Galatic Grey it is a sensible starting point for riders who want a capable gravel bike now and the option to add bags, racks and bigger tyres as their riding grows.
Why You'll Like It
Simple, dependable 1x11 gearing
SRAM Apex 11-speed shifting with an 11-42 cassette and a 40T crank gives you a usable spread of gears for gravel climbs and road cruising without a front derailleur.
Nimble, stable handling
The frame is set up for quick, responsive steering that still feels steady and in control on rougher descents.
Room to run wider tyres
Clearance for 700x45 mm or 27.5x2.1 inch tyres lets you fit meatier rubber for chunkier gravel and rougher terrain.
Tubeless-ready wheels
Paradigm rims and GR1 Team Issue tyres are tubeless-ready, so you can go tubeless with sealant for lower pressures and extra grip.
Mounts for carrying your gear
Integrated frame bag mounts plus rack and mudguard mounts make it straightforward to carry water, tools and luggage.
Who Is It For?
Riders who want to move beyond smooth roads: weekend explorers looking for unpaved lanes and farm roads outside the city, and commuters whose route mixes tarmac with rough patches. The disc brakes and wide-range gearing suit varied Indian road surfaces and monsoon riding.
It is also a good first gravel bike for someone coming from a road or hybrid bike, with a straightforward drivetrain and the mounts to grow into bikepacking or touring.
Good to Know
- Available in sizes 52, 54 and 56. Crank length (170 or 172.5 mm), handlebar width (40 or 42 cm), stem length and saddle width vary by size, so check the size chart before ordering.
- Choose pedals to suit your riding, from flat pedals to clipless. Trek's pedal guide is a helpful starting point.
- Wheels and tyres are tubeless-ready and use Presta valves, so a Presta-compatible pump head is needed for pressure checks.
- Mechanical disc brakes are easy to adjust by cable tension, and regular chain lubrication keeps the SRAM Apex drivetrain running smoothly.
