Pro bike: Dan McConnell’s Trek Domane Koppenberg

Trek Factory Racing team bike of the world cup mountain biker

Dan McConnell might be ranked third in the world for cross-country mountain biking, but the Australian rider joined the Trek Factory Racing team at the 2015 Tour Down Under. It was his first WorldTour event, and although he insists mountain biking is his prime focus, we suspect he’ll accompany the team in more events to come.

Most of the Trek Factory Team would normally ride the Emonda or Madone road bikes, but Trek Australia told BikeRadar that the majority of the team rode the Domane at the Tour Down Under, because of Australia’s generally poorly surfaced roads.

The domane is unique for its isospeed seat tube ‘decoupler’, allowing the seat tube to pivot between the seat tube for compliance:

The Domane is best known for its seat tube that pivots within the top tube

However, this isn’t the usual upright and relaxed Domane endurance bike you’ll find at your local Trek dealer, but the recently released Domane Koppenberg. This special version combines the smooth riding IsoSpeed seat tube ‘decoupler’ with far racier geometry borrowed from the new Emonda range.

With a non-replaceable steel derailleur hanger and a limited size range of 56, 58 and 60 and 62cm, the Domane Koppenberg frameset is designed for the WorldTour team first, and consumer sales second.

We recently featured McConnell’s Trek Superfly FS 9.9 with prototype XTR Di2, which he rode at the 2014 mountain bike world championships. This Domane shares the same brand and colour, but it’s otherwise a very different beast.

Standing at 1.8m (5ft 11in), McConnell rides a slightly larger-than-expected 58cm frame size, with a relatively sensible 125mm length stem.

The di2 climber shifter pod offers rear shifting from the handlebar tops:

The Climber shifter pod is a common addition to many Trek Factory Racing bikes

As one of the first riders in the world to race Shimano’s XTR Di2, it’s not surprising that McConnell’s road bike features Shimano Dura-Ace Di2. Something that we’ve seen quite often among Trek Factory riders in the past, McConnell uses a Climbers shifter for rear derailleur shifting control while his hands remain on the handlebar tops.

Longer cranks are common in mountain biking to help with leverage. Here, McConnell keeps his bike fit as close to that of his mountain bike as possible with a 175mm SRM Shimano crankset.

Sitting in the frame’s left chainstay, a bontrager duotrap ant+ sensor reads wheel speed:

The Bontrager DuoTrap sensor usually offers both cadence and speed, although here it’s only used for the latter

SRM states that ultimate data accuracy requires a wheel-based speed sensor and so Trek Factory Racing use the Bontrager ANT+ DuoTrap that sits integrated within the left chainstay of the frame.

As a Trek-owned company, Bontrager joins Shimano as another major component sponsor of the Trek Factory Racing team. For 2015, the team will use some Bontrager components with ‘team-issue’ graphics that make the brand more obvious – the red stem and wheels are clear examples of this.

McConnell’s choice in wheels doesn’t waver from the rest of the team, with 50mm deep Bontrager Aeolus 5 DR3 carbon tubulars shod with 24mm width rubber from VeloFlex.

Same as his mountain bike, mcconnell uses a bontrager montrose pro saddle in a 138mm width:

Other than the 11-speed chain and Di2 wiring, perhaps the only component that’s the same as his mountain bike is the Bontrager Montrose Pro saddle in a middle width.

At 7.43kg (16.35lb) including a SRM head unit, the complete weight of McConnell’s ride is on the upper-end for WorldTour, with the extra weight coming from the Domane frame and SRM power meter.
