Quintana RooService Course Tri
A drop-bar triathlon bike rather than a classic tri bike: Quintana Roo takes the frameset of its Service Course aero road bike and fits it with a normal road cockpit, so it stays legal for draft-legal sprint and Olympic-distance racing and road races. Clip-on extensions can be added to turn it into a non-drafting middle- or long-distance bike. The frame has a deep aero down tube, a narrow extended head tube, room for 36 mm tires, a T47A threaded bottom bracket and a UDH hanger. Builds range from mechanical Shimano 105 to SRAM Force AXS, all with hydraulic disc brakes.

Our verdict
No overall score: there's no complete-bike price to rate
For triathletes who race draft-legal sprint and Olympic events, or who want one bike for road racing and the odd 70.3 with clip-ons. It's a real aero road frame with wide tire clearance and a threaded BB from a moderate starting price, but it keeps road seat angles, offers no integrated hydration or storage in its specs and isn't on the UCI approved list.

Short wheelbase: tends to feel more agile in corners and less planted on long straights.

Short front centre: more weight on the front wheel, which can make the front feel lighter to steer.

Good to know
Fit
Quintana Roo describes the geometry as its most aggressive drop-bar race geometry, with a longer, lower position than its endurance-geometry Service Route Tri. Seat tube angles are 73.5-74.5°, a road-bike range rather than a tri-bike one.
SourceRacing
Quintana Roo's World Triathlon pro Blake Bullard races the Service Course Tri in draft-legal events.
SourceRacing
Quintana Roo calls the Service Course Tri frame UCI-legal and sells it for draft-legal racing, but the Service Course is not on the UCI's list of approved framesets (version 2026.10.02); the only Quintana Roo frames listed are the QRL and SR-Series road bikes.
SourceHistory
The Service Course frameset launched as an aero road bike in January 2025. Quintana Roo claimed it was at least 3.6 W faster than its predecessor, with 36 mm tire clearance, a T47A threaded bottom bracket and a UDH hanger, in sizes XS to L.
SourceVersions
Quintana Roo built the Service Course Tri for draft-legal triathlon, where aerobars and TT bikes aren't allowed: it keeps standard drop bars for those races and takes clip-on extensions for non-drafting events.
SourceVersions
The Service Course Tri uses the same frameset as Quintana Roo's Service Course aero road bike, with triathlon-specific saddles, gearing and a clip-on compatible cockpit. The road version's cockpits are not set up for clip-ons.
