Checkpoint ALR Frame Set | Trek Bikes (INE)

Overview

You believe there's nothing better than a day spent exploring. You want to build up a single durable, ultra-versatile gravel bike that's ready for any off-road adventure, bike-packing tours and all-around utility.

A sturdy aluminium frame with a progressive geometry that's stable at speed and efficient when you're grinding up a climb, hidden cables that won't interfere with bags, rack and mudguard mounts and integrated frame bag mounts, a carbon fork and a cartridge-bearing headset. Built for 12 mm thru axles, flat-mount disc brakes and a T47 bottom bracket.

Build your gravel bike exactly the way you want. The Checkpoint ALR Frame Set gives you a solid head start on your dream build with a lightweight frame, carbon fork and gravel-specific details like extra mounts for endless customisation options.

All-new progressive geometry is quick and nimble yet keeps you stable and in control on fast, choppy descents
Massive tyre clearance means you can use tyres up to 45 c for extra traction and stability in any conditions
Integrated frame bag mounts and rack and mudguard mounts make it easy to carry gear and water
Internal cable routing keeps things smooth, quiet and clean

'Trek's new Checkpoint SLR 9 eTap is an excellent gravel race bike, built with features and geometry that calm rough surfaces without the handling feeling vague or sluggish. After two months on it, I can say that the bike we named the 2021 VeloNews Bike of the Year has only got better.

'Overall, the new Checkpoint is a wonderful gravel bike. It’s faster, handles better and is more suited to the needs of today’s gravel rider.'

"As with other bikes with similarly long front ends, the revamped Checkpoint is easier and more confidence-inspiring to ride off-road on even moderately steep or loose terrain than before."

"Trek has revamped its Checkpoint line-up, with the updated gravel bike coming in not one but three different flavours, catering for the needs of go-fast racers, rough-and-ready adventurers and riders looking for a versatile N+1."

Checkpoint ALR 5

Features

For quick, nimble handling that still keeps you stable and in control on rougher descents.

Lots of clearance means you can run meatier tyres (700x45 mm or 27.5x2.1") for tackling chunkier gravel and terrain.

Integrated frame bag and mudguard mounts make it easy to carry gear and water.

Trek’s premium-grade aluminium is hydroformed into size-specific tubes that provide the perfect balance of stiffness and weight.
