Wilier Supersonica SLR FAQs
Everything you need to know before ordering a Wilier Supersonica SLR through Tri Harder.
How much faster is the Supersonica SLR than Wilier's previous TT bike?
Wilier claims a 16% improvement in aerodynamic efficiency over the Turbine SLR, backed by wind tunnel testing at 50km/h.
Does the Supersonica SLR have integrated hydration?
Yes — the downtube shape transitions directly into an integrated 550ml water bottle, built into the frame’s aero profile rather than added afterwards.
Can the Supersonica SLR be set up with a front derailleur?
Yes — while it’s built around a 1x setup as standard, there’s a removable front derailleur mount for a 2x groupset if that suits your build better.
What's the claimed frame weight?
Wilier claims 1,450g for the frame and 550g for the fork.
Is the Supersonica SLR available as a complete build or frameset only?
Currently available as a frameset — every build is a custom spec conversation, giving full control over groupset, wheels and cockpit to match your position and budget.

What We Think Of The Wilier Supersonica SLR
The Supersonica SLR isn't a refresh — it's Wilier starting from a blank sheet with TT specialist Stefan Küng involved from day one. The integrated bottle, aero seatmast and fully internal cabling aren't gimmicks, they're the result of genuinely rethinking every tube on the bike. This is a frame for someone who's already serious about their TT position, not a first step into the discipline.
What we like
- Genuine ground-up redesign, developed with direct input from a WorldTour TT specialist rather than an incremental update
- Integrated 550ml bottle built into the downtube shape itself, not an aftermarket aero bottle bolted on
- Removable front derailleur mount means it's not locked into 1x — real flexibility for triathlon builds
Worth knowing
Best For
Serious TT and triathlon racers who want the most advanced aero platform available, rather than someone looking for a starter tri bike.
