Our verdict
No overall score: there's no complete-bike price to rate
A versatile aero frameset for riders who want to race road and short-course triathlon on one bike: a reversible seatpost, room for 35 mm tyres, mechanical or electronic groupsets and a standard stem. The design dates from 2018, Ceepo publishes no aero figures and it is sold only as a frameset.

Good to know
Fit
Geometry is from Ceepo's Mamba-R chart, which titles the bike 'aero all road'. The chart lists a 955 mm wheelbase for size L, shorter than size M (975.8 mm); it is left out here as a likely error. Seat tube angles in the chart don't fall steadily with size (76, 75, 75.7, 74.6, 74°) and are kept as published.
SourceIntegration
Shift wires and hoses are routed from the stem into the head tube; Ceepo supplies grommets for Shimano Di2, SRAM eTap (blank), mechanical cables and the rear brake exit, plus a Di2 battery adaptor.
SourceRacing
Ceepo highlights the Mamba-R's use by Team BIKE AID, including stage wins and Anton Schiffer's win at the 2024 German uphill national championship.
SourceHistory
The disc-brake Mamba-R was added to the UCI list of approved framesets on 16 July 2018.
