Merida Time Warp Team
The Time Warp Team is possibly the only bike with a modular headtube. The upper section of the headtube is actually a removable and swappable piece that can be selected to reduce headset spacers. The downtube is narrow and has a subtle C-shapes swoop. The rear triangle has exceptionally deep tubes. The front caliper is external and the rear brake hides under the bottom bracket. Pro triathlete Matty White rides the Time Warp on the pro circuit in the States, so you could potentially see one of these, but they aren’t in shops.
