Overview

BuildE117 SRAM Force AXSMamba-R frameset
Build notes—Sold 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.
