The TSTRevo Carbon Time Trial Bike
Handsling has spent more than 12 months developing the TSTRevo, a dedicated carbon time trial bike with aerodynamically optimised tube profiles and a bespoke, fully adjustable carbon TT cockpit. The frame is UCI-approved, and its exceptional stiffness ensures rider power translates directly into speed – whether you’re targeting your club 10 mile TT or a long distance event.
We build each TSTRevo around your position through Remote Tailored Sizing – setting pad height/reach, extension length and saddle height – then assemble with your chosen groupset, wheels and finishing kit in the UK.
Your Fit. Your Spec. Your TSTRevo.

TSTRevo Features
The UCI-approved Handsling TSTRevo (pronounced "tester-evo") represents the cutting edge of modern time trial and triathlon engineering. Proven across national titles, regional time trials, and dominant triathlon bike legs, it is meticulously designed 100% in-house to slash drag, maximize power transfer, and dominate the race of truth.
Precision Frame Engineering
Manufactured using bladder-wrapped internal EPS moulds for superior material compaction, the frame maximizes structural integrity and delivers absolute tracking stiffness.
Bespoke & Highly Adjustable Cockpit
Includes a proprietary carbon base bar, forearm cups, and D-shaped extensions with extensive stack, reach, and lateral adjustments for a completely optimised aerodynamic fit.
Real-World Aerodynamic Tubing
Truncated aerofoil tube shapes and a short head tube dramatically minimize frontal surface area, allowing the frame to slice through the wind with maximum efficiency.
High-Performance BSA Bottom Bracket
Proven in testing as the most aerodynamic option, the stiff, narrow-section BSA shell ensures absolute power transfer through the rear stays without wasting a single watt.
Aggressive Race-Fit Geometry
A steep seat tube positions the rider directly over the bottom bracket for maximum pedaling leverage, while the ultra-stiff front end ensures stable tracking at high speeds.
Disc Brakes & 32mm Tyre Clearance
Powerful disc brakes provide elite all-weather stopping control, paired with generous 32mm tyre clearance for reduced rolling resistance and exceptional cornering grip.
"It's hands down a race machine, but with compliance and comfort. It's the perfect choice for any triathlete." Simon Davis, Team GB
A1ROevo - Ultegra Di2. Sound service. Beautfiul bike. Rip-roaring ride. You won't be disappointed...
Stiff, nimble and really quick, yet more than comfortable…..that frame is seriously top!
I was free wheeling when others where pedalling lol. It just cut through the air! Roll on next event!

TT bike vs triathlon bike – what’s the difference and which should I pick?
TT bike vs triathlon bike – what’s the difference and which should I pick?
A TT bike is built for cycling time trials under UCI rules: a pure aerodynamic bike frame, adjustable TT cockpit (pads/extensions), and typically no on-frame storage. A triathlon bike is geared more to long-course comfort and often integrates storage/hydration. We designed the TSTRevo so it can be set up for either TT or triathlon, making it a highly versatile choice to cover both disciplines.
What are the benefits of carbon time trial bikes vs aluminium?
What are the benefits of carbon time trial bikes vs aluminium?
Short answer: carbon gives you better stiffness-to-weight, and improved vibration damping – so it’s easier to hold a fast time trial position for longer.
- Aero shaping freedom: Carbon can be moulded into smoother, deeper profiles and cleaner junctions than most alloy designs – reducing drag on a dedicated aerodynamic bike frame.
- Stiffness-to-weight: Targeted carbon lay-ups add torsional stiffness at the head tube/BB without unnecessary mass, helping more of your effort become speed.
- Ride feel you can hold: Carbon damps road buzz better than alloy, making it easier to stay low on the pads and maintain pace.
- Integration & routing: Carbon construction supports tidy internal runs and integrated solutions that keep the airflow clean.
If outright aero efficiency and efficient power transfer are your goals, carbon TT bikes are the best choice. We’ll confirm the best route during Remote Tailored Sizing and UK-assemble the build to your spec.
What is the ideal time trial bike fit?
What is the ideal time trial bike fit?
There isn’t one “ideal” fit – there’s a sustainable aero position you can hold. Key principles: set pad stack/reach so you’re compact yet breathing freely; match extension length/tilt to keep the head steady; place the saddle so hip angle stays open for power. We determine this via Remote Tailored Sizing, then fine-tune on the adjustable cockpit (pads fore/aft & lateral, stack spacers, extension reach) before assembling in our Hampshire, UK factory.
Are TT bikes heavier than road bikes?
Are TT bikes heavier than road bikes?
Often slightly, yes. A TT bike may weigh more than a carbon road bike due to added carbon layup, the TT cockpit and deeper wheels, but it’s typically faster on flat/rolling courses because reduced aerodynamic drag outweighs small mass differences. For climbs or technical routes, wheel/tyre choices and fit can be tuned to balance handling and speed.
What’s the usual lead time for a custom TT bike build?
What’s the usual lead time for a custom TT bike build?
A Handsling custom time trial bike will typically take 4-6 weeks, depending on paint choice and component availability. If you have an event deadline, we’ll advise in-stock options and confirm a build slot before we start assembly.
Do you offer carbon TT framesets-only so I can move parts across?
Do you offer carbon TT framesets-only so I can move parts across?
Yes – TT frameset-only options are available (subject to current stock). We’ll check compatibility for your groupset, brakes, wheels and cockpit before you transfer parts.
Do you offer fittings in the UK?
Do you offer fittings in the UK?
Yes. Come to our Hampshire HQ or complete Remote Tailored Sizing online. We’ll set your TT position, agree frame size and cockpit set up then proceed to assembly. To arrange, email sales@handslingbikes.com or call 01420 612700.
