RS7 105 Mechanical
Carbon road + aero platform, fitted and supported by Mox.
There is a large gap between a normal road bike and a dedicated triathlon bike. For riders shopping below dedicated-tri-bike territory, the RS7 is where we usually start: the lowest-cost complete race-ready platform we currently recommend.
Mechanical
Shimano 105 mechanical shifting at the levers. The lower-cost way into the RS7.

Shimano 105 Mechanical, Angel Wing White
Why the RS7
A complete, race-ready platform
Carbon platform
A carbon frame that rides like a proper road bike, so it earns its place on group rides and long training days, not just race day.
Carbon wheels
Carbon wheels come stock, so the build starts race-ready instead of needing a wheel upgrade first.
Built-in power meter
A dual-sided Branta power meter crankset (52-36T) comes stock, with ANT+ and Bluetooth through the X-LAB app. You can train and pace by power from the first ride.

Built by Mox
The RS7, built around you
Mox custom build. Not included with the stock bike.
The stock cockpit comes off so we can fit a separate stem and road bar that accept clip-on aerobars and set reach around your position.
Photographed: the Mox-built RS7 Di2. Fit, sizes, and parts are set for each rider.

Fitting
Choosing your size
The cockpit gets built around your position. Ideally we establish it before finalizing cockpit dimensions; if you already own the bike, we can fit and refine the system afterward. The fitting shapes:
- • Saddle position
- • Stack
- • Reach
- • Cockpit dimensions
- • Pad position
- • Extension position
Geometry
RS7 Geometry & Sizing
Stack and reach decide where the bars and aero extensions can sit. We read them against your fit to choose the size, stem, and spacers before the bike is built.
