Brand Overview & History
DT Swiss is synonymous with Ratchet freehub hubs (240/180/350), dependable wheel systems, and constant aero co‑development with Swiss Side. In June 2025, DT launched Gen‑3 ARC aero wheels: wider (22 mm internal), deeper (55/65/85 mm), and (counter‑trend) more V‑shaped to reduce drag and stabilise steering — tailored around Continental AERO 111 tyre pairings. Lines split into ARC 1100 (180 hubs) and ARC 1400 (240 hubs).
On hubs, DT introduced 240 Ratchet DEG (2024) with 90‑tooth ratchets for 4° engagement, trading some weight for snappier pick‑up and easy service — sitting alongside Ratchet EXP 36T (standard 240/180). The flagship 240 page reiterates EXP improvements (bearing spacing, tool‑free service).
Rider feedbacksentimentreviews
Praises
Reliability, serviceability, and balanced aero handling. The ARC 2025 update is well‑received for integrating wider tyres without sacrificing stability; ERC 1100 remains a favourite for endurance road. DEG hubs satisfy riders seeking faster engagement while keeping DT’s field‑serviceable ethos.
Concerns
Some forum chatter notes that, at 22 mm IW, ARC isn’t as ultra‑wide as certain rivals (24–25 mm IW), and net weights can still be ~1,48–1,59 kg for the 55s. There was also an ARC recall for specific batches (test units unaffected), which riders should check by code.
Overall
DT remains a set‑and‑forget choice with a more modern aero stance and continued hub support.

Professional Industry Reviews
Cycling Weekly describe ARC 2025 wheels as wider, lighter (per depth), and more aero, with 55/65/85 mm options; the V‑shift counters the wider frontal area, aiming for better crosswind manners
GRAN FONDO’s test of ARC 1100 55 reports 1,483 g tested with stability gains, while also flagging DT’s recall notice and code checker.
Where DT-Swiss wins?
DT’s pitch is consistent handling + serviceable hubs. IW (22 mm) is now the conservative middle ground.
On hubs, DEG gives near‑Hydra engagement without leaving DT’s ratchet simplicity.
Brisbane Cyclist Perspective
If you want hassle‑free speed with easy parts support, DT remains a top pick: ERC 1100 for rougher roads and crosswinds; ARC 55/65 if you chase watt‑saving on long, flat runs.
On MTB, 240 DEG gives lively pick‑up for punchy climbs without sacrificing DT’s service ethos.
