Speeder Cycling SC-R55D

The Speeder Cycling SC-R55D is a carbon integrated road disc frameset that has generated significant discussion among forum users. Key attributes include a price of approximately $660 for the frameset plus shipping, frame weights ranging from 842g (unpainted size 535) to 930g (painted size 51), and material using Toray M40J T700/T800 carbon (with later mentions of T800/1100 and MJ40). It features BB86.5 press-fit bottom bracket (with T47 option later available), full internal cable routing, Di2 compatibility, flat mount disc brakes, UDH (Universal Derailleur Hanger), and max tire clearance of 700x32c (though users report fitting up to 34-35mm actual width, and one user fits 34c Vittoria Corsa with room to spare). The frame comes in sizes from 45cm to 57cm with integrated handlebar/stem options. Users generally praise the frame's quality, value, and performance, with long-term reviews (8,000-13,000 km) reporting minimal issues. Noted drawbacks include the BB86 bottom bracket, seatpost clamp design (slipping, hard to reach saddle bolt), and occasional communication delays with Speeder. Recent posts highlight progressive geometry (long reach, moderate stack) and the ability to achieve sub-7.4kg builds. The carbon layup has been updated to Toray M40J T800/T1100.
