XXS (480)
Engineered to slice through air. Built to win against the clock.
The Winspace TT5 is a UCI-compliant time trial frameset designed for riders who race against the clock at every level — from local club events to national championships. Dressed in the 2026 MMM Team Edition livery, it combines Toray T800/T700 carbon construction with a suite of purpose-built aero features: a patented closed thru-axle fork, fully adjustable aerobars, sliding saddle rail, and an ultra-slim aero seatpost. Six sizes from XXS to XL ensure a precise fit.
UCI Compliant — Race it straight out of the box. Every dimension of the TT5 meets UCI regulations for sanctioned events. Race at local time trials, national championships, or UCI-level events without modification.
What makes this worth it
Patented Closed Thru-Axle Fork
A fully enclosed thru-axle fork design streamlines the front end, eliminating exposed surfaces that create drag. Cleaner airflow, higher speed for the same effort.
Fully Adjustable Aerobars
Height, reach and extension angle all adjust independently. Dial in your most efficient TT position and fine-tune it as your fitness or race demands evolve.
Ultra-Slim Aero Seatpost
A razor-thin 400mm seatpost minimises frontal area and smooths airflow at the rear. The slimmest profile Winspace offers — maximum aero gain behind the saddle.
Sliding Saddle Rail
Millimetre-perfect saddle positioning for maximum power output and aerodynamics. The sliding rail mechanism lets you find exactly the right fore-aft position for your body and event.
T47-68mm External BB
Outboard T47 threading — the same proven standard used in the Winspace G3 and G5 road frames. Maximum stiffness and power transfer, with broad crankset compatibility.
Ultra-Short Chainstay
410mm across all six sizes delivers snappy acceleration and direct power transfer. In time trialling, every watt counts — the TT5 wastes none of them.
