Domane now available with disc brakes and bolt-thru axles

Trek have launched a disc-equipped version of the Domane, available at two price points and both borrowing bolt-thru axle technology from their mountain bikes. The Domane 4.0 will cost £1,600 and the Domane 6.9 £6,000, and both will be available this month. 

We speculated on the launch of the Domane Disc earlier this year as Keith Bontrager told us he believed Trek would almost certainly launch a disc-equipped road bike in the near future. His prediction has come true, with Trek taking the obvious decision to use their endurance model, the Domane, rather than the racier Madone, for their first disc-equipped road bike. They've already launched a cyclocross bike with disc brakes this year, the Boone CX.

There’s been much debate about wheel axle design on disc-equipped road bikes, and Trek have opted to move away from traditional 9mm quick release axles and adopt bolt-thru technology from their mountain bike range. Called Closed Convert dropouts, they have a 15mm front axle and a 142x12mm rear axle. They can be easily converted to a traditional quick release axle for increased wheel compatibility.

New axles means new wheels, and they’ve developed a new Bontrager Affinity Elite Disc wheelset with bolt-thru hubs. The rims are tubeless-ready - Bontrager have been doing tubeless for a while already. The wheels use interchangeable axle end caps so they can be used on any bike with just a simple change of the end caps required. The wheels have a claimed weight of 1,655g.

An exciting upside of the switch to disc brakes is that Trek says both will happily take wider tyres (though they don’t say how wide) and mudguards, because the removal of the caliper opens up more clearance.

Trek will offer the Domane 6.9 costing £6,000 and the Domane 4.0 at £1,600. Both bikes will be available this month. 

“The response we’ve seen from riders about the Domane has been unprecedented and adding a disc brake option further opens the door for riders to expand how and where this bike is ridden,” says Trek Road Bike Brand Manager Michael Mayer.

£6k for the 6.9 apparently.

I'll have to get saving then!

For £6,000 they couldn't be bothered to route the front cable through the fork?

Zip ties? *Really*?

Maybe they had their reasons? I'm not a fan of internal cable/hose routing anyway so it doesn't look so bad to me

Agreed. Looks terrible.

Looks cracking to me (bar the shitty front cabling). Wonder if they'll still do the 4 series frame-set on Project One ?

Cannot recommend discs and wide rims enough; I recorded my second fastest ever descent down from Christmas Common last night.. in biblical rain with water sheeting across the road. The truly gifted may not need discs, but for the rest of us they make a very noticeable difference!

Drooling over this.  105

Funnily enough, was just talking to the owner of my LBS last night and he said Trek were about to launch a disc-equipped Domane, couple of models to start but then the full range will be disc-equipped. He reckons they're going for more "durable", UK-road suited bikes with the Domane, whereas the Madone will be a faster and lighter bike.

Be interesting to see what the 4-series bike is like, more my price point, sadly.

That looks ace. Apart from the disc brakes and bolt-through axles.

I'm so stoked to see a nice satin black bike with black glossy graphics - I'm utterly fatigued by seeing all these stylistically-bereft brightly coloured shiny bikes out there so it's good to see someone doing something original.

Zip ties are a big NO NO. On a £6,000 bike... Come on. It reminds me when Specialized use to slap on the Di2 battery with zip ties from the water bottle mount when that first launched. Stop rushing things to market and do them properly.

Actually zip ties seem to be more common these days. Check out Cannondale's cross bikes. Their high end model Super x Hi Mod Disc Black inc. has zip ties... Doesn't bother me at all, and a lot easier to work on opposed to internal routing

Internally routing a road bike front brake hydraulic line is difficult. It has to come out of the back of the shifter, into the handle bar, through the stem, into the steerer tube, down the fork and out just above the caliper. All of those parts then become specific to that bike, moving the stem and bleeding becomes a right pain and uses a longer line. Doing it like the Dogma-K where it goes into the top of the fork (where the cable tie post goes) and out at the caliper just looks half done as it doesn't remove the cable clutter from the front end.

My MTB has little black C-clips which hold the brake lines in place, not as cheap as a cable tie and probably not as secure, but re-usable so you can remove the line temporarily while cleaning.

So you can either spend £1600 or £6000. No choices in between?

Odd.

I was interested until I found out the £1,600 bike has 9 speed sora.....

And echoing the above poster, dodgy, no models in-between, how much would 10 speed tiagra or 105 be?

I think once the new 105 hydro brake/mech shifter comes out, we'll see a mid priced 5 series bike.

I'd quite like to see Cancellara faffing about trying to get the bolt thru axle sorted in a hurry after a wheel swap in a hailstorm.

You've never used a bolt-thru axle then?

Bolt through may be the best engineering solution but I've been using disc brakes with regular old qr axles on my MTBs for over 10 years and never once had a wheel move or pop out. Still, makes sense for the 99% of cyclists who don't have to fret about losing 5 seconds changing a wheel.

Axles are a necessity when equipping wheels with disc brakes. They position the wheel back so that the disc falls exactly between the callipers of the hydraulic brake. With QR, this can be tricky, especially in a hail storm.

Actually this Domane Disk sets the first step towards the next revolution in road cycling. Larger diameter wheels, now that advances in materials and technique have made wheels stiff enough. A slightly larger, broad rimmed wheel would make such bicycles ultra performant on rougher surfaces. MTB's made the step and 26 inch wheels have disappeared from new models in favour of 27.5 and 29 inch. (with the exception of Specialized). The whole transition took less than 2 years, thanks to the massive improvements brought about by the new formats, without ANY downside.

Let the pro peloton get stuck in the past and the rest of us forge forward. Eventually, the pros will catch up, after all that is what they are good at.

Except it seems to be missing eyelets for guards, so you couldn't attach a decent set. Shame, this would make a great winter bike. Any word on whether they're planning this in the range?

You'll find axles are a necessity on any wheel. As for through-axle wheel changes, 5 seconds lost for a racer could spell disaster.

Discs are nice for commuters or wet weather bikes but for performance bikes they don't make sense.

They're the ones where you unscrew the axle bolt, slide the axle out, put it on the floor, swap wheels, reach out for the axle about to roll down the hillside, slide it back through the frame and hub, try to get the end cap back on without cross threading, then realise the neutral support wheels use hubs a different diameter axle to your frame anyway, if I'm right?  3

If it rides as good as it looks and I've had a few Treks with the new 105 I'd be putting that high on my list

I don't know if this is meant to be sarcastic, text isn't good at portraying piss-taking. If it is fine, if it isn't you really have bought the marketing crap hook line and sinker!

From the photos of the 6.9 i've seen, it looks like the 'vanishing' mudguard mounts are still there. Have a butchers here

in pictures 14 and 18. I'd be slightly surprised if they'd removed them from the 4 series certainly, not so the 6 series, but looks like you might be in luck.

'Performance' meaning 'followed by service car'?

I can see some genuine issues with the use of discs in regulated racing but I'm glad that, for a change, manufacturers have realised that the UCI is a complete irrelevance to most riders.

Besides, I'm pretty sure you could engineer around the front QR issue with either a cowled dropout and close fitting lever/cap - a bit like a thru axle but with a slot or just face the dropout forward so braking pulls the wheel into the slot. Easy.

The insane thing in my eyes, if you want an aggressive disk equipped road bike from Trek, buy the boone and fit slicks.

The head tube on a Domane is in my opinion far too long.
