RidleyTriton Fast
Ridley's first bike made purely for triathlon, launched in October 2025 and developed with 70.3 world champion Jelle Geens. It borrows aero know-how from the Noah Fast road bike and pairs a geometry that sits the rider further forward over the bottom bracket, with a longer reach and taller head tube, with a fork whose rake can be switched between three settings. Water is carried in an internal frame reservoir with a drinking tube, food and tools go in modular packs on the frame, and the Monoriser cockpit adjusts in height, reach and angle and comes off with two bolts for travel. It is sold through Ridley's Elite Series configurator with custom paint, as a frameset or with SRAM groupsets.

Our verdict
Overall
out of 100, average of 7 categories
A long-course tri bike for riders who want an internal reservoir, frame storage and a genuinely adjustable cockpit at mid-market money, backed by a transferable lifetime warranty. The trade-off is a Ridley-only basebar, riser and seatpost, and the two upper builds come only as 1x13.

Good to know
Design
Flip chips in the fork set the rake to 45, 50 or 55 mm. Ridley says the shortest rake gives the most stable, slowest steering and the longest the quickest.
SourceAerodynamics
Ridley chose 1x13 drivetrains with aero chainrings for the top two builds to drop the front derailleur and cut drag.
SourceFit
Ridley lists only the 4ZA basebar for the frame, saying it was designed with that bar for aero integration. Extensions mount to the Monoriser Wing.
SourceCompatibility
The 34 mm clearance refers to the tyre's actual measured width, not the size printed on it. In 1x the frame takes chainrings up to 70T; in 2x it takes up to 62/42T.
SourceRacing
Jelle Geens rode the Triton Fast to defend his Ironman 70.3 world title in Marbella in November 2025. British pro Rebecca Anderbury also raced one there.
SourceHistory
Ridley calls the Triton Fast its first bike designed purely for triathlon. It was announced in October 2025, and Jelle Geens worked with Ridley's engineers during development and served as its first test rider.
SourceVersions
At launch Bici.PRO reported four configurations from €3,999 to €8,699. Ridley's Belgian site now lists €3,999 (frameset), €5,999 (Rival AXS 2x12), €8,999 (Force XPLR 1x13) and €10,999 (Red XPLR 1x13).
SourceVersions
In its Triton Fast vs Dean Fast comparison (November 2025), Ridley says an important difference is that the Dean Fast complies with UCI rules (8:1 tube ratios, compensation triangles) for riders who race under them, so the Triton Fast is not a UCI-legal frame. It is also absent from the UCI list of approved framesets.
