Finishes

The chameleon effect

Close detail of the VEGA-TT-24S frame in Chameleon Blue

Chameleon Blue

A metallic finish that shifts between deep teal and steel blue as the light moves across the frame. The principal colourway, and the one most of the photography is shot in.

Same carbon layup, same geometry, same build as the other two — the paint is the only difference.

Close detail of the VEGA-TT-24S frame in Arctic White

Arctic White

Flat white against the black carbon wheelset. The frame shapes read most clearly in this finish — you can see the aero sections in the down tube and fork legs.

Shows road grime faster than the other two. Worth knowing if the bike lives outdoors.

Close detail of the VEGA-TT-24S frame in Field Green

Field Green

A muted matte green, closer to olive than to a racing colour. The quietest of the three, and the one that looks least like a bike shop floor model.

Matte finishes mark more easily than gloss and are harder to polish out.

The bike

Built for one position,
held for a long time

Frame

Carbon frame and fork, BB86 press-fit. Chainstays are 400mm and bottom bracket drop is 75mm on every size — the rear end and pedalling height never move, only the front end grows.

LTWOO, not Shimano

ER9 is LTWOO's 12-speed mechanical road groupset. It is a large part of why this bike costs what it does rather than twice as much. We would rather you knew that now than found out later.

Cockpit

Base bar and extensions are a single integrated carbon unit. There is no separate stem, so reach is set by frame size and extension position — worth knowing before you choose a size.

The build

Closer in

Carbon disc rear wheel and rear derailleur
Front disc brake rotor and hub
Rear hub and cassette

Full carbon

Frame and fork are carbon fibre, as are the seatpost, the one-piece cockpit and both wheels. There is no aluminium in the frameset.

Disc brakes

LTWOO disc brakes front and rear, with rotors on both wheels. Two independent braking systems, which is what UK road use requires.

12-speed

LTWOO ER9 mechanical groupset with a 50/34T chainset, 170mm cranks and an 11–32T cassette. Enough range for a rolling course.

Rider height ranges are the manufacturer's guidance, not a fitting service. Reach and stack decide the fit, and the integrated cockpit limits how much reach can change after purchase.

The build

Part by part

Integrated cockpit

Base bar and extensions are one carbon unit. No separate stem, so reach is set by frame size.

Carbon disc rear

Permitted in triathlon and time trial events. Not permitted under UCI rules in mass-start road racing.

Before you order

Not sure between
two sizes?

Send us your height, inside leg and any current bike fit numbers. We would rather talk it through than process a return — the cockpit is one piece, so the size you choose is the size you ride.
