Build notesSold as a frameset kit (frame, fork, reversible seatpost, FSA SMR stem and headset, plus thru-axles, seat clamp and Di2 battery adaptor). The USD price is from the 'Mamba-R Frameset Kit' listing in Ceepo's own online shop (excluding VAT and duties); the same frameset is sold as the road Mamba-R. That listing names older colours (Glossy Blue, Hirro Fade, White, Chameleon, Pink) and a 30-53T chainring range, so confirm the current version with a dealer.Box contents per Ceepo's 2026 assembly guide: frame, fork, reversible seatpost, headset, FSA SMR stem, seat clamp and mini clamp, thru-axles, expander, Di2 battery adaptor and cable grommets.

Fit notesRoad geometry (seat angle 74-76 degrees depending on size); the reversible seatpost moves the saddle forward for a tri position. 2x chainrings from 50/34 to 54/40, 1x from 34T to 54T. FSA SMR stem 80 mm (XS, S), 90 mm (M), 100 mm (L) or 110 mm (XL). The SMR system allows up to 25 mm of stem spacers, using two-piece spacers that can be fitted or removed without re-cabling.The reversible seatpost changes the saddle position for road or triathlon use. Chainrings from 50/34 to 54/40 for 2x and 34T to 54T for 1x. Ceepo's assembly guide gives a maximum stack above the head tube of 25 mm of stem spacers plus the 10 mm bearing top cap and 18 mm cable cover spacer; the two-piece spacers can be removed without re-cabling.
