COVID-19 Important collection and delivery information
Where delivery times are stated as a month this is based on the latest information from the manufacturer. These dates should be treated as a guide and may be subject to change. Due to an increase in global demand for bicycles and the disruption in supply during the COVID-19 pandemic supply chains have become very strained. Lead times are based on factory and shipping schedules both of which can be disrupted by delays in component supply and shipping/port capacity.
Should you place a future order with us for a bicycle we will monitor the bike’s ETA and keep you informed of any changes.

Size Options & Purchase
Trek's Checkpoint is a gravel road bike designed with high-quality parts that will that hold up for long, rugged miles on pavement, dirt, and even the most treacherous gravel roads.
ALR models feature 300 Series Alpha Aluminium which is ruggedly reliable but superlight too. The ALR frame also features key pieces of tech such as; tapered head tube, press fit bottom bracket, flat-mount disc brakes, Stranglehold dropouts, 12 mm thru-axles, Control Freak cable duides, internal cable routing and a 3S chain keeper.
Checkpoint combines the speed and stability of a road bike with the rugged offroad capability of a cyclocross bike. It also comes ready to roll with a wealth of adventure-ready features, like adjustable Stranglehold dropouts, massive tyre clearance, and extra mounts that make it super versatile and easy to customise.
Geometry is comfortable for the long haul and rough roads, but aggressive enough to provide the speed and ride-feel most gravel riders are looking for. Compared to Trek's Boone cyclocross race bike, Checkpoint features a nearly identical reach, slightly taller stack, and lower bottom bracket height. Chainstay length and wheelbase are the same. The lower bottom bracket provides the additional stability at speed, while maintaining a tight wheelbase, long reach, and relatively low stack height keeps Checkpoint fast and manoeuvrable.
Stranglehold dropouts allow the rider to adjust the bike's geometry and gearing based on the requirements of the day's ride. For example, the longest setting makes the bike more stable for longer rides and bikepacking. The dropouts also allow for quick & easy conversion to singlespeed.
The stock 40mm tyres hit the sweet-spot for a lot of riders, but running other widths quickly changes Checkpoint's identity. The rider hitting crushed limestone trails to link pavement will love firm and fast-rolling 28mm slicks, while the dedicated dirt road explorer can go up to 45mm to tackle the ruttiest, rockiest routes.
Checkpoint is covered in mounts. Mounts on the seattube and downtube allow riders to fit three bottles in the main triangle, or position two bottles low while leaving room for a frame bag. There's also room for one more bottle under the down tube. Lowrider fork mounts will take a rack & bags. Rear rack mounts give more room for cargo, and hidden fender mounts keep the ride clean in even the worst weather.
The Trek Checkpoint is the bike to fulfil your imagination.
Note: This bike features Bontrager's Tubeless Ready rim system which enables a straightforward conversion to a full tubeless set up. To complete the conversion to tubeless you will need to fit additional parts. This include specific rims strips (W543622), valves (W429879) and, appropriate tubeless tyres and sealant.
IMPORTANT: This bicycle is supplied without pedals.

This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicycles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and responsibility on which size to purchase is yours.
