A two-bolt titanium stem from 5DEV's Custom Shop in San Diego. The one-piece clamp slides onto a riser bar without the fuss of a four-bolt faceplate, and the short 32 mm length puts the bar right over the headset to make the most of a modern slack head angle.
Highlights
- Machined titanium, raw finish
- 35 mm bar clamp; black 31.8 mm aluminium shims included
- 32, 40 or 48 mm length, 37 mm stack
- 133 g at 32 mm with hardware (5DEV figure)
- Made in San Diego, California
The two-bolt clamp
5DEV calls the design VRTS (Variable Radius Geometry). Instead of a removable faceplate, the bar sits in a one-piece clamp closed by two bolts, and 5DEV says it goes on a riser bar without scratches and more easily than a four-bolt stem. Each stem is machined by a trained technician in 5DEV's Custom Shop.
Options
| Length | Notes |
|---|---|
| 32mm | Shortest option; 5DEV says it slams the bar over the headset. 133 g with hardware. |
| 40mm | Middle length. Weight not published. |

All three have the 35 mm clamp, 37 mm stack and raw titanium finish.
Compatibility & fit
Bar: 35 mm clamp. The black 31.8 mm aluminium shims in the box let you run a 31.8 mm bar.
Steerer and rise: 5DEV doesn't publish the steerer clamp size or the rise, so ask us to confirm fit for your fork before ordering.
Fitting: 5DEV's instructions call for anti-seize on the bolts, never titanium bolts, tightening evenly and a torque of 5 Nm. The Tune Cycles workshop can fit the stem and set your bar and headset preload as a separate workshop service.
5DEV backs its products with a limited 5-year warranty from the date of manufacture, against defects in materials and workmanship. If 5DEV confirms a defect, it replaces the affected part with a comparable model. Talk to us before replacing anything: 5DEV voids the warranty if a part from another maker is fitted in place of the 5DEV component.
This is in addition to your rights under the Australian Consumer Law. Keep your proof of purchase.
For warranty support, return the product to Tune Cycles and we'll manage the claim with 5DEV's Australian distributor.
