| Hydration details | THIRSTpac reservoir in the raised top tube, about 0.9 L according to road.cc. It has a quick-fill port, a cover to stop sloshing and a drinking straw that runs to the cockpit. Other reviews quote 26 oz and 30 oz. | Removable reservoir inside the frame, in the space a down tube would normally take: 1.4 L on sizes S to XL, 1.2 L on XS.

| Fit notes | According to road.cc, riser height and angle, extension width and length, armrest fore-aft and width, and basebar grip height are all adjustable. Cyclenews' reviewer still found the elbow rests and extensions too close together. | Arm-pad height is set by sliding the monoriser mast and the pads can be tilted. Slowtwitch reports dozens of pre-drilled pad mounting positions. |
| Aerodynamics | ||
| Manufacturer aero claims | 1.9% faster than the previous IA across -20° to 20° yaw, and 4% faster across -12.5° to 12.5°, the range Felt says riders spend about 90% of their time in | — |
| Travel, maintenance & warranty | ||

| Headset bearings | — | 40 x 52 x 7 mm, 45°x45° bearings (shared with the GS1 and NS1) |
| Derailleur hanger | — | Proprietary: Ventum rear derailleur hanger (same part as the 2020-2022 GS1) |
| Maintenance | — | The Di2 junction or SRAM Blipbox sits in the nose cone at the front of the cockpit. If externally clamped brake levers such as TRP HD-T910 are used, Ventum advises trimming 3 cm off each end of the basebar and fitting the alloy reinforcement inserts. |
| Proprietary parts | — | Hydration reservoir, aerobar system and seatpost are specific to the One Disc |
| Frame warranty | — | Limited lifetime warranty on frame, fork and seatpost for the original owner |
