The decision between a 2x double-chainring setup and a 1x single-ring drivetrain is one of the biggest for a gravel build. The Campagnolo Ekar 1x13 groupset leans fully into a single front chainring and a wide 13-speed cassette, promising a broad range without a front derailleur. But before you buy, you need to know what this groupset actually includes and what it doesn't.
Quick verdict
The Campagnolo Ekar Groupset 1 x 13 Speed Gravel Bike 172.5 mm 40T 9-42 Cassette is priced at USD 589.00 and is made up of original OEM parts, with an Italian origin and a condition described as new other. The crank arms are 172.5mm, the chainring is 40T, and the cassette spans 9-42 teeth. A chain is not included. So this is a thoughtfully arranged 1x13 gravel gruppo, but not a complete ready-to-ride package.
Who it suits
This groupset is for a gravel rider who wants the simplicity of one chainring and the wide range that a 9-42 cassette can offer. The 40T chainring combined with a cassette starting at 9 teeth can give a high enough top gear for many gravel roads, while the 42T low gear helps on climbs. It also suits someone who is comfortable sourcing a compatible chain separately, and who prefers a 172.5mm crank length.
What stands out
The standout detail is the 1 x 13 architecture. That's 13 rear speeds paired with a single 40T ring, and the 9-42 cassette is what makes the spread work. The 172.5mm cranks are a specific spec to note - this length is a common middle ground, not the longest or shortest option. The group is built around OEM parts, and the Italian origin adds a clear point of reference for anyone who values that detail, though the most practical detail is the missing chain.
The main trade-off
The biggest trade-off is obvious: the chain doesn't come with this groupset. That means the true cost of your build is the USD 589.00 for this group plus whatever you spend on a chain. The group comes complete as shown, so what's in the photos is the full extent of what you receive. Also, because it's a 1x groupset, you won't have a front derailleur or multiple chainrings - by design, you're committing to a single-ring setup.
Campagnolo Ekar Groupset 1 x 13 Speed Gravel Bike 172.5 mm 40T 9-42 Cassette
Choose this groupset if you want a wide 13-speed gravel range from a 40T chainring and a 9-42 cassette, and if you're ready to add a chain on your own. The limitation is that missing chain - you'll need to budget extra before you can ride.
Bottom line
If the 1x13 layout and a 9-42 cassette match your gravel riding, and you're okay with sourcing a chain, this Campagnolo Ekar groupset is a concrete option for your build. If you want a truly complete groupset with chain included, you'll need to look elsewhere or buy a chain separately.
