Frames
| Material | 7020 T6 aircraft aluminum, TIG-welded |
|---|---|
| Weight | 1800-2100 g (depending on size) |
| Headset | 1 1/8″ Ahead (SHIS EC 34/28.6 – EC 34/30) |

V1 (2011)

First prototype, build from leftover tubing and random MTB parts. The top tube was way too short, so I had to make a Frankenstein seatpost to reach a comfortable position on the bike.
V2 (2011)
First small batch of 11 frames. Sizes XS-L, 26″ wheels only. Disc brake and canti brake mounts. CNC yoke and watercut dropouts. Very long top tubes. Known weaknesses: top tube, dropouts.
V3 (2012-2013)
Almost identical to V2, with some adjustments: CNC dropouts, slightly shorter top tubes. Addition of the XL size (700c wheels). Known weakness: top tube.
V4 (2014-2017)
S-bend chainstays instead of the previously used CNC yoke. Thicker top tubes. Known weakness: chainstays.
V5 (2018-2023)
Like V4, but with stronger chainstays.
700c frames (2014-2017)
Build for a limited time only…
V6 (2023)
| Material | 7020 T6 aircraft aluminum, TIG-welded |
|---|---|
| Weight | 1800-2100 g (depending on size) |
| Headset | 1 1/8″ Ahead (SHIS EC 34/28.6 – EC 34/30) |
| Bottom bracket | BSA/british thread, width: 73 mm |
| Seatpost | Ø 31.6 mm |
| Seatpost clamp | Ø 35 mm |
| Rear hub compatibility | 135 mm hub spacing, 10 mm axle, quick release |
| Wheel size | Depending on frame size, see geometry table |
| Dropouts | Sliding, 15mm travel (derailleur hanger or disc-brake dropouts available) |
| Brake mounts | Optional IS2000 disc brake (see above) |

V6.1 (2025)
Same as V6, with two differences:
- no possibility to mount a rear disc brake
- straight seat stays
