Trek Domane SLR

The new Trek Domane has an adjustable rear IsoSpeed, new front IsoSpeed and new IsoCore handlebars all in the name of versatility.

Today Trek has launched its new iteration of the Domane platform and it is significantly updated from the previous model. We’ve seen sneak peaks of the bike at Strade Bianche and the Tour of Flanders, where Trek rider Fabian Cancellara piloted it, but now the details are out. The new Trek Domane has an adjustable rear IsoSpeed, a new few IsoSpeed and new IsoCore handlebars all designed to make the bike more versatile.

Adjustable IsoSpeed decoupler

The new rear IsoSpeed decoupler is comprised of two separate seatubes, with a small slider in between. The slider can be moved up and down to alter the distance between the two tubes, and thus alter the amount of deflection. Moving the slider closer to the bottom bracket makes the bike more comfortable (for cobbled racing perhaps) and moving it higher up reduces the amount of flex (for riding on smooth tarmac roads).

The current Trek Domance has an average deflection of 3.75mm, but Trek claims the new one is capable of 4mm of deflection on it’s smoothest setting (tunable to 3.5mm and 3.15mm also) – a claimed increase of 14% over the original Domane. 

This should make the bike more versatile as when you’re riding on smooth roads at home (not London…) you can stiffen up the rear end of the bike and remove any unwanted ‘bounciness’.

New front IsoSpeed

The new Domane has an IsoSpeed system at the front end of the bike too to balance out the riding sensations. Trek claims the new front IsoSpeed adds between 5-9% increased deflection at the handlebars depending on the stem length. Trek claims it’s a 10% improvement over a traditional road bike by 'allowing the steerer tube to rotate independently from the head tube.' - whatever that means...

IsoCore handlebar

The average aluminium handle bar deflects approximately 4.25mm while riding over rough surfaces, and a carbon bar approximately 3.85mm. The new IsoCore handlebar only deflects by 3.25mm, so Trek claims it is stiffer under load will still isolating the rider from bumps in the road surface. 

How is this achieved?

‘Constructed with a continuous inner layer of a specialized thermoplastic elastomer encased in proprietary OCLV, the IsoCore handlebar improves damping of high-frequency vibration with a reduction of vibration by 20% over standard carbon handlebars.’

Increased tyre clearance

The new Domane has increased tyre clearance to align with the modern trend of regular riders running increased volume tyres. The rim-brake model now accepts 28mm tyres and the disc-brake model accepts 32mm tyres.

Flat mount disc brakes

The new Domane is available immediately with FlatMount disc brakes and is equipped with 12mm bolt-thru axles.
