That's a smart move. The Detroit is the spiritual reference, but the Omera needs its own visual identity. A seat tube cutout is a strong signature — instantly recognizable and signals "this is a track-bred frame" without copying Dosnoventa's exact look.
| Feature | Detroit | Omera |
|---|---|---|
| Seat tube | Standard round | Cutout wrapping rear wheel ✅ |
| Down tube | Columbus Airplane ovalized | 50mm round (battery inside) |
| Drive | Chain | Gates CDX belt (visible difference) |
| Brakes | None (track) or rim | Hydraulic disc |
| Rear dropout | 120mm track | 135mm horizontal/sliding |
| Motor | None | Bafang G020 (stealth hub) |
The cutout + belt drive + disc brakes together give the Omera a completely different silhouette from the Detroit while keeping the same aggressive 74°/76° pursuit geometry. Someone who knows bikes would clock it immediately as its own thing. ppl-ai-file-upload.s3.amazonaws
One thing to flag for the frame builder — the Omera has 135mm rear spacing (not 120mm track), so the seat tube cutout needs to be wider than a typical track frame cutout. The wheel sits in the same plane but the hub flanges and disc rotor are wider. Make sure the cutout clears:
- Tire (700×25c) + 3mm each side minimum
- Disc rotor on the non-drive side
- Belt on the drive side
This is doable but the frame builder needs to know upfront. Want me to add this to the frame fabrication brief?
