Quintana RooService Course
Quintana Roo's aero road bike, launched in January 2025 to replace the SRsix, which Quintana Roo says it beats by at least 3.6 W. It borrows tube shapes from the V-PRi triathlon bike, clears 36 mm tyres, uses a threaded T47A bottom bracket, UDH and a non-proprietary headset, and works with standard or one-piece internally routed cockpits. Every bike is built to order with the buyer's choice of groupset, wheels, cockpit and paint.

Our verdict
No overall score: there's no complete-bike price to rate
A versatile, built-to-order aero road bike for riders who want to pick every part: standard or one-piece cockpits, 36 mm tyre clearance, T47A, UDH and a lifetime warranty. There is no fixed MSRP or frame weight, only four sizes and an aero claim only against the SRsix.

Good to know
Fit
Rider heights are from Quintana Roo's size guide; the ranges overlap. The top tube is the virtual horizontal length and trail is given for a 28 mm tyre.
SourceRacing
Quintana Roo calls the Service Course UCI-legal. The frame is not on the UCI's list of approved framesets checked in October 2026 (only the QRL and SR-Series appear for the brand).
SourceHistory
Quintana Roo introduced the Service Course on 29 January 2025 in Chattanooga, Tennessee, as its fastest UCI-legal aero road bike. It replaced the SRsix, which the brand now calls its previous-generation aero road flagship.
SourceVersions
The configurator also offers Shimano 105 mechanical, SRAM Rival E1 2x and SRAM Force E1 2x kits (surcharges $1,110, $1,810 and $3,090), and wheels from DT Swiss (E 1800 Spline, ARC 1600 Dicut), HED (Vanquish V45, V62), ENVE (SES 4.5) and Zipp (454 NSW). In October 2026 the site listed the bike from $3,555 during a sale ($3,628 regular) for the cheapest configuration; at launch Quintana Roo quoted from $4,599 / €4,999.
