A simple upgrade for bike braking systems, RTDHO Disc Brake Adapter allows larger rotor sizes for steadier control on demanding trails. Riders facing long descents or technical singletrack gain confidence from reduced fade and crisper modulation. Is the upgrade compatible with your frame and calipers, and will it suit your riding style?
⚡ At a Glance
- • Braking Performance: Enhanced control and better heat dissipation when using larger rotors
- • Best for: Mountain bikers, e-bike riders and gravel cyclists wanting stronger stopping power
- • Not ideal for: Frames without post or side mount fittings or incompatible calipers
Enables upgrading rotor sizes to improve braking consistency and reduce fade. Lightweight construction balances strength with minimal additional mass.
Reduced brake fade on long descents – thanks to larger rotor compatibility
Larger rotor sizes increase surface area and improve heat dissipation, which helps brakes maintain consistent friction under prolonged use. Compatibility with 140mm, 160mm, 180mm and 203mm rotor options allows choosing a size suited to riding intensity.
Stronger, more reliable stopping power on extended descents and technical trails. Riders gain steadier modulation and less drop in braking performance during sustained use.
Lightweight durability – with CNC-machined aluminium alloy construction
CNC machining produces accurate tolerances while using aluminium alloy keeps structural strength high but weight low compared with heavier metal alternatives. The chosen alloy resists corrosion and stands up to wet, muddy conditions.
A robust mount that endures off-road conditions without adding unnecessary mass to the bike. The durable finish helps maintain performance season after season.
Flexible front and rear installation – with post and side mount compatibility
Designed for both post-mount and side-mount setups, the adapter repositions the caliper to match larger rotor diameters. Included bolts and clear directional markings assist correct alignment during installation.
Swap rotor sizes between bikes or adapt braking setups for different terrain with minimal fuss. Quick alignment reduces installation time and helps ensure reliable caliper positioning.
