Choosing drivetrain and brakes for a 1x9 bike build often starts with a compatibility puzzle: shifters, derailleur, crankset, cassette, chain, and brake levers all need to work together. The MicroShift Advent 1x9, Complete Drivetrain, All Mechanical, with extra brake pad simplifies that by bundling the major components in one purchase at USD 160.00.
Quick verdict
This is a used microSHIFT Advent 1x9 groupset removed from a Marin Nicasio+ Gravel Bike. The package includes the groupset with a clutch, shifters, brakes, chain, crankset, rear cassette, and cables. Everything worked flawlessly when the parts were pulled. For someone building or maintaining a mechanical 9-speed gravel bike, this bundle removes much of the guesswork around matching drivetrain and brake parts.
Who it suits
The rider who wants one package to cover the main drivetrain and braking pieces will appreciate what is included here. Since the parts came off a gravel bike, the bundle fits a gravel-bike context. It is also a practical fit if you are comfortable with pre-owned components and want to complete a 1x9 build without separately selecting each part.
What stands out
MicroShift Advent 1x9, Complete Drivetrain, All Mechanical, with extra brake pad
The bundle covers the primary mechanical drivetrain and braking components: shifters, brakes, chain, crankset, rear cassette, and cables. The Advent 1x9 groupset includes a clutch, which is a meaningful detail for a gravel-oriented mechanical setup. All-mechanical operation means shifting and braking are handled without electronic actuation.
The strongest practical reason to choose this set is the completeness of the package. You are not sourcing shifters from one place and a cassette from another; the main pieces are together in one purchase. The main trade-off is condition: the components were removed from a Marin Nicasio+ Gravel Bike. If you are set on installing never-used parts, this set is not that.
Meaningful trade-offs
The main thing to weigh is that the parts came from another bike. Because they were pulled, they are pre-owned. The bundle is ultimately a used component set rather than a complete bicycle, so the buyer still brings the bike and remaining build pieces to the table.
Bottom line
For USD 160.00, the MicroShift Advent 1x9 Complete Drivetrain offers a single-package route to a mechanical gravel 1x9 drivetrain with brakes. If you are comfortable with used parts, it covers the key drivetrain and braking pieces. If you require brand-new components, this is not that bundle.
