The Boardman AiR TT 9.2 is so well balanced and composed it’s almost boring. The fun comes when you see what this can do to your split times, while still leaving you fresh for the run.

+ Composed and balanced handling, and excellent aero efficiency

Its quiet character can disguise just how quick this bike is but the Boardman AiR TT 9.0 is a benchmark for fatigue-free long-distance speed and efficiency at an affordable price.

Read the full Boardman AiR TT 9.0 review

Cervelo P2 (2012)
£3,999.99
madison.co.uk

Cervelo’s bikes have topped the Kona bike count for years and many of the tallies on the Ironman bike sheet are built on the evergreen P2 frameset. While the P2 is now a little way behind the Canadian brand’s flagship bikes such as the Cervelo P5, its confident, user-friendly and naturally speedy ride mean its classic status remains very much intact.

Read the full Cervelo P2 review

Pros
+ Lightweight frame with good handing and a comfortable ride
+ Standard brakes, BB and fork allow a range of upgrade options

Cons
– Aerodynamics are good but lack the latest integrated component tweaks
– Decent rather than dramatic power delivery and steering precision

Cervelo P3C reviewCervelo P3C (2012)
£2,199.99 (frame and fork)
cervélo.co.uk, madison.co.uk

If there’s any bike that doesn’t need an introduction it’s Cervelo’s P3 Carbon. Officially the most successful aero bike ever built, it’s the choice of thousands of pros and privateers alike. Though it’s expensive and behind the aero curve, the P3C is still a blisteringly quick, accurate, surefooted, and insatiably predatory ride.

Read the full Cervelo P3C review

Pros
+ Outstanding propulsion transfer and locked-in ride position breed PBs
+ Impressively light, phenomenal handling and crisp controls

Cons
– Not as aero or comfortable as the best contemporary frames
– Cervelo’s uncompromising character comes at a price

Felt DA2Felt DA2 (2012)
£6,199
saddleback.co.uk, feltbicycles.com

This has long been one of our favourite bikes, with Felt’s multi-adjustable and impressively comfortable chassis always impressive. The DA2 comes with Di2 electronic shifting and is still a superbly comfortable bike, but frame and wheel flex are obvious in the handling if you’re a more muscular rider.

Read the full Felt DA2 review

Pros
+ Very comfortable, easily adjustable, aerodynamic chassis
+ Fully integrated Shimano Di2 shifting as standard

Cons
– Skinny tubes make it a frame of two halves when you start to push hard
– Wheels are fast, but less convincing when cornering and cranking

Felt B12Felt B12 
£2,099
feltbicycles.com

The B12 offers a wide fit range in a comprehensive Ironman-ready complete bike package and does the long-haul, low-stress job it’s designed to do well. It’s not the fastest or sharpest on more technical or rolling courses but the B12 is a ready-to-race long-distance specialist

Read the full Felt B12 review

Pros
+ Great frame fit, flattered with size-specific componentry
+ Smooth ride with noticeable wheel and frame speed-sustain

Cons
– Weight and frame/wheel flex dull dynamic performance

Giant Trinity Composite 2Giant Trinity Composite 2 
£1,899
giant-bicycles.com

Inspiring power delivery and a superb riding position make the Giant Trinity Composite 2 a top performer. It never struggled to keep pace on climbs, and often led the pack over the top of shallower grades that it could carry plenty of speed on to the bottom of. It’s an absolute bargain, too

Read the full Giant Trinity Composite 2 review

Pros
+ Super-upgradeable, high-performance frame
+ Reliable kit and sorted cockpit create a ready-to-race bargain

Cons
– Tiagra chainset and wheels create hefty overall weight
– Climb/novice-friendly ratios mean gears are gappy on the flat

The alloy Moda Mossa adds an even more affordable option to the British company’s Sharp and Interval TT bike line-up. The combination of light wheels and excellent rider position mean the component compromises are overcome to deliver a quick, upgrade-friendly starter bike for triathlon at a sensible price.

Pros
+ Aero position and low weight create an efficient ride

Pros
+ Lightweight, reasonably smooth and responsive aero frameset

£3,665

Testing Ridley’s Dean RS alongside some direct competitors proves its distinctive but seemingly very effective aerodynamics and its composed comfort and handling character.

Read the full Ridley Dean RS review

Pros
+ Impressively light and responsive, with power-friendly speed sustain
+ Excellent default ride position plus fatigue-reducing comfort

Cons
– Slab rim design means the T100 wheel option (Dean RS 1312A) is a ‘calm day only’ choice
