A stout aluminium frame with rack and mudguard mounts, a vibration-absorbing carbon fork, a 2x10 Shimano GRX drive train with lower gears for grinding up hills or through rough gravel, hydraulic disc brakes for all-condition stopping power and wide 700x40c gravel tyres for added stability and traction.
Bring it on, gravel! Checkpoint ALR 4 is a high-value gateway to a world of adventure. It's rugged, fast, comfortable and has an amazing amount of tech for its price. Though it's made to stand up to the rigours of gravel roads, the frame geometry and accessory mounts make it a great choice for road rides and commutes too.
- The Checkpoint ALR 4 introduces you to the exciting new frontier of gravel riding at a value that can't be matched
- This bike is exceedingly versatile and suited to a wide variety of riding styles, including gravel rides, bikepacking and daily commutes
- Mounts on the seat tube and both sides of the down tube make it easy to carry extra gear and water
- Massive tyre clearance means you can use tyres up to 45 c for extra traction and stability in any conditions
- The horizontal sliding dropout makes it easy to fine-tune your geometry or run singlespeed
At Bikeology, we pride ourselves on our aftersales service and the quality of the products we sell. If we can’t stand over a product or a service, then we simply don’t sell it.
Every bike we sell comes with a lifetime warranty on the frame. A lifetime warranty on the frame entitles you to a new frame should there be any failure caused by fatigue or defective manufacture. Should this unlikely failure happen, we will process your warranty claim and rebuild your bike from the ground up completely free of charge*.
All other parts fall under the manufacturers warranty, but rest assured, we will do everything we can to get your bike back running smooth as silk as soon as possible, after all, you put your confidence in Bikeology. Should a problem arise, well, now it’s our time to prove you made the right decision in Bikeology.
As part of our drive to make your cycling experience the best it can be, we offer two years FREE servicing with every bike we sell.
What does this actually mean?
ALL labour charges are waived for 2 years from the date of purchase. For example, if your bike needed a service and a new tyre, the typical cost would be €40 plus €16 for a basic tyre. With our two years FREE servicing, this would only cost €16. If your gears need an adjustment, no charge at all!!! Buckled a wheel? Don’t worry, no charge at all!!! Annual service, No Charge……you get the idea!!! ZERO Labour charges for two years**.
*Any new parts needed will be assessed on a case by case basis.
** Fork, Shock and Dropper seatposts not included.
Trek began in 1976, when a pair of determined guys set out to make the best bicycles the world had ever seen. Their vision was grounded in unswerving principles: the product would be of the highest quality craftsmanship and it would bring the joy of cycling to a broader audience.
It was this philosophy that brought Bikeology and Trek together. We know that a quality bike will bring joy and passion to people from all walks of life. With our partnership with Trek, we will continue to bring the joy of the bicycle to more and more people. Some will simply use the bicycle as a tool in their daily life, for others, the bicycle will become a passion that will define the course of their life.
Bikeology and Trek have one thing in common, we are driven by adventure, guided by our history, inspired by community, enchanted by the freedom of the open road and committed, always, to creating, using and providing the world’s greatest bicycles.
