Whether you're starting with a bare frameset, replacing a drivetrain, or upgrading the bike you already love, Boulder Nordic & Cycle Sport can help plan and complete the project.
Modern bikes are increasingly integrated, and component compatibility can quickly get complicated. We'll help ensure the parts work together before the project starts, then professionally assemble, install, and adjust everything so the finished bike works as it should.
Complete Custom Bike Builds
Have a frameset and a vision? Bring us the project at any stage.
We can help with component selection, compatibility and complete assembly for road, gravel, mountain and other performance bikes.
| Custom Bike Build | $225 |
| Frame Swap / Bike Build | $300 |
Additional labor may apply for unusually complex internal routing, integrated cockpits, suspension setup, or other specialized work.
Drivetrain & Groupset Upgrades
Changing a drivetrain often involves more than swapping a derailleur. Cassette range, freehub compatibility, chainline, bottom bracket standards, crank compatibility, brake systems and electronic components all need to work together.
We can help plan and install complete mechanical or electronic drivetrain upgrades.
| Complete Drivetrain Installation | $125 |
| Groupset Installation | $225 |
| Hydraulic Groupset Installation | $300 |
Electronic Drivetrains & Power Meters
We install and configure electronic shifting systems, power meters, and other electronic components.
That can include component installation, firmware updates, pairing, configuration, and basic setup so the system is ready to ride when you leave the shop.
Wheels, Tires & Tubeless
Wheels and tires can dramatically change the way a bike rides.
We offer wheel builds, wheel installation, tubeless conversions, tire inserts, and help selecting wheels and tires appropriate for your bike and the way you ride.
| Wheel Build | $85 |
| Tubeless Conversion | $30 / wheel |
| Tire Insert Installation | $35 |
Cockpit & Fit-Related Upgrades
Handlebars, stems, saddles and controls affect both comfort and handling. Modern integrated cockpits can also make seemingly simple changes surprisingly complicated.
We can help evaluate compatibility and install new bars, stems, controls, saddles and related components.
Suspension Upgrades & Setup
We can install and set up forks, shocks and other suspension components for mountain bikes.
Proper setup matters as much as the component itself. We'll help establish an appropriate starting point for pressure, sag, and other available adjustments based on the rider and bike.
Bike Assembly
Bought a bike that arrived in a box? We can professionally assemble, inspect, and adjust it before you ride.
| Build Boxed / Shipped Bike or Prepare Bike for shipping (includes box) | $100 |
| Build New Bike From Box not purchased from BNCS | $150 |
| Boxed E-Bike Build | $200 |
Assembly pricing can vary based on the bike's complexity and the amount of assembly required.
Have a Project in Mind?
You don't need to arrive with a complete parts list.
Tell us what you're trying to accomplish, what bike you're starting with, and how you ride. We'll help work through the options, compatibility and scope of the project before ordering parts or beginning the work.
